fWotD Episode 3277: Bombing of Obersalzberg Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles. The featured article for Saturday, 25 April 2026, is Bombing of Obersalzberg. The bombing of Obersalzberg was an air raid carried out by the Royal Air Force's Bomber Command on 25 April 1945 during the last days of World War II in Europe. The operation targeted Obersalzberg, a complex of residences and bunkers in Bavaria which had been built for Adolf Hitler and other key members of Nazi Germany's leadership. Many buildings in the complex were destroyed, though Hitler's residence and the bunker network were only slightly damaged. Two Allied bombers were shot down with the loss of four airmen, and 31 Germans were killed. Historians have identified several motives for the attack on Obersalzberg. These include supporting Allied ground forces, demonstrating the effectiveness of the British heavy bomber force, convincing die-hard Germans that the war was lost and obscuring the memory of pre-war appeasement policies. The attack was conducted by a large force of 359 heavy bombers in an attempt to destroy the bunkers located below Obersalzberg, from which the Allies feared that senior members of the German government would command an Alpine Fortress. After difficulties locating and marking the targets were overcome, the bombers attacked in two waves. The approximately 3,000 people at Obersalzberg sheltered in bunkers, and the nearby town of Berchtesgaden was undamaged. Hitler was in Berlin at the time of the attack and Hermann Göring, the only senior Nazi at Obersalzberg, survived. While the raid on Obersalzberg was celebrated at the time, it is little remembered today. Most of the Allied personnel involved in the operation took satisfaction from attacking Hitler's residence, and it received extensive media coverage. As the Alpine Fortress proved to be a myth, most post-war histories made little mention of the operation. This recording reflects the Wikipedia text as of 01:14 UTC on Saturday, 25 April 2026.

fWotD Episode 3276: Ornithoprion Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles. The featured article for Friday, 24 April 2026, is Ornithoprion. Ornithoprion is an extinct genus of cartilaginous fish. The only species, O. hertwigi, lived during the Moscovian stage of the Pennsylvanian subperiod, which spanned from 315 to 307 million years ago. Its fossils are preserved in black shales from what is now the Midwestern United States. The study of Ornithoprion was performed primarily via x-ray imaging, and at the time of its discovery it represented one of the best known holocephalans of the Paleozoic era. The classification of the genus has been the subject of debate due to its unique anatomy, and it is now placed in the order Eugeneodontiformes and the family Caseodontidae. Ornithoprion's genus name, which may be translated from Greek as 'bird saw', was inspired by the animal's vaguely bird-like skull and the saw-like appearance of the teeth in the lower jaw, while the specific name honors German zoologist Oscar Hertwig. Ornithoprion had a unique projection of its lower jaw termed the mandibular rostrum, which was covered by a beak of fused bony scales and the function of which in life is not known. It inhabited shallow, seasonal marine and brackish water environments, alongside a variety of other cartilaginous fishes. The rounded shape of Ornithoprion's teeth suggests that it hunted hard-shelled invertebrates, and bite marks and damage to some of its fossils indicate that it was in turn fed on by other carnivores. Ornithoprion was small relative to other members of its order, with a cranium length of up to 10 cm (3.9 in) and an estimated body length of up to approximately 91 cm (36 in).

fWotD Episode 3275: Beyoncé Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles. The featured article for Thursday, 23 April 2026, is Beyoncé. Beyoncé Giselle Knowles-Carter ( bee-ON-say; born September 4, 1981) is an American singer, songwriter, actress, and businesswoman. Known for her vocal ability, artistic reinventions, and live performances, she is widely regarded as one of the most culturally significant figures of the 21st century. Credited with shaping popular music, Beyoncé is often deemed one of the greatest entertainers of all time. Beyoncé rose to fame in the late 1990s as the lead singer of Destiny's Child, one of the best-selling girl groups of all time. Her debut solo album, Dangerously in Love (2003), became one of the best-selling albums of the 21st century. After Destiny's Child disbanded in 2005, Beyoncé released the funk-imbued B'Day (2006) and starred in the drama film Dreamgirls (2006). Her marriage to rapper Jay-Z and portrayal of Etta James in the biopic Cadillac Records (2008) influenced her pop-oriented double album I Am... Sasha Fierce (2008). Through the 2000s, Beyoncé garnered the US Billboard Hot 100 number-one singles "Crazy in Love", "Baby Boy", "Check on It", "Irreplaceable", and "Single Ladies (Put a Ring on It)". After forming the management company Parkwood Entertainment, Beyoncé embraced traditional R&B and soul on 4 (2011). The electronic-influenced Beyoncé (2013) popularized surprise and visual albums, inspiring the setting of Friday as Global Release Day, while the eclectic Lemonade (2016) sparked sociopolitical discourse and was the best-selling album of 2016. Her ongoing trilogy project—consisting of the queer-inspired dance album Renaissance (2022) and the Americana-rooted country record Cowboy Carter (2024)—has highlighted the overlooked contributions of Black pioneers to American musical and cultural history, spawning the respective US number-one singles "Break My Soul" and "Texas Hold 'Em". Beyoncé is one of the best-selling music artists of all time, with estimated sales of over 200 million records. She is the most RIAA-certified female artist and the only woman whose first eight studio albums each debuted atop the US Billboard 200. One of the most-awarded artists in popular music, she is the recipient of a record 35 Grammy Awards, a Primetime Emmy Award, and a Peabody Award. Beyoncé is the most-awarded artist of the BET Awards (36), MTV Video Music Awards (30), NAACP Image Awards (32), and Soul Train Music Awards (25). The first woman to headline an all-stadium tour, she is the highest-grossing Black live music artist of all time.

fWotD Episode 3274: Nihilism Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles. The featured article for Wednesday, 22 April 2026, is Nihilism. Nihilism is a family of philosophical views that question the existence of any objectively meaningful purpose, moral value, truth, or knowledge. Nihilistic views span several branches of philosophy, including ethics, value theory, epistemology, and metaphysics. Nihilism is also described as a broad cultural phenomenon or historical movement that pervades modernity in the Western world. Existential nihilism asserts that life has no objective meaning or purpose. The idea that all individual and societal values are ultimately pointless has been associated with various responses. They range from general indifference and existential crises to transformative reinterpretations of established ideals and a creative embrace of personal meaning-making. Moral nihilism, a related view, denies the objective existence of morality, arguing that moral evaluations and practices rest on misguided assumptions without any foundation in external reality. In epistemology or the theory of knowledge, nihilism challenges knowledge and truth. According to relativism, knowledge, truth, or meaning are relative to the perspectives of specific individuals or cultural contexts. This implies there is no independent framework to assess which opinion is ultimately correct. Skeptical interpretations go further by denying the existence of knowledge or truth altogether. In metaphysics, one form of nihilism states the universe could have been empty without any objects. This view holds that there is no fundamental reason for why something exists rather than nothing. Mereological nihilism asserts there are only simple objects, like elementary particles, but no composite objects, like tables. Cosmological nihilism is the view that reality is unintelligible and indifferent to human understanding. Other nihilist positions include political, semantic, logical, and therapeutic nihilism. Some aspects of nihilism have their roots in ancient philosophy in the form of challenges to established beliefs, values, and practices. However, nihilism is primarily associated with modernity, emerging in the 18th and 19th centuries, particularly in Germany and Russia through the works of Friedrich Heinrich Jacobi and Ivan Turgenev. It took center stage in the thought of Friedrich Nietzsche, who understood nihilism as a pervasive cultural trend in which people lose the traditional values and ideals guiding their lives as a result of secularization. In the 20th century, nihilist themes were explored by Dadaism, existentialism, and postmodern philosophy. This recording reflects the Wikipedia text as of 01:01 UTC on Wednesday, 22 April 2026.

fWotD Episode 3273: Sinestro Corps War Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles. The featured article for Tuesday, 21 April 2026, is Sinestro Corps War. "Sinestro Corps War" is an American comic book crossover event published by DC Comics in its Green Lantern and Green Lantern Corps titles. Written by Geoff Johns and Dave Gibbons and drawn by Ivan Reis, Patrick Gleason, and Ethan Van Sciver, the 11-part saga was originally published between June and December 2007. In addition to the main storyline, four supplemental "Tales of the Sinestro Corps" one-shot specials and a Blue Beetle tie-in issue were concurrently released. The story centers on the Green Lanterns of Earth—Hal Jordan, Kyle Rayner, John Stewart and Guy Gardner—and the rest of the Green Lantern Corps as they fight an interstellar war against the Sinestro Corps, an army led by the former Green Lantern Sinestro who are armed with yellow power rings and seek a universe ruled through fear. A 1986 Alan Moore "Tales of the Green Lantern Corps" story was the thematic basis of the storyline. Many characters were changed, killed off, or re-introduced as a result of the event. Critical and fan reception to "Sinestro Corps War" was highly positive. Many reviewers ranked it among the top comic books of the year, and the storyline's first issue garnered a 2008 Eisner Award nomination for Best Penciller/Inker or Penciller/Inker Team. The storyline was also a financial success, and several issues underwent multiple printings. "Sinestro Corps War" is the second part of a trilogy in the Green Lantern storyline, preceded by the 2005 miniseries Green Lantern: Rebirth. The conclusion of "Sinestro Corps War" sets up the third and final part of the trilogy, Blackest Night, which was published in 2009.

fWotD Episode 3272: Sci-Fi Dine-In Theater Restaurant Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles. The featured article for Monday, 20 April 2026, is Sci-Fi Dine-In Theater Restaurant. The Sci-Fi Dine-In Theater Restaurant is a theme restaurant at Disney's Hollywood Studios, one of the four main theme parks at Walt Disney World. Established in May 1991, the restaurant is modeled after a 1950s drive-in theater. Walt Disney Imagineering designed the booths to resemble convertibles of the period, and some servers act as carhops while wearing roller skates. While eating, guests watch a large projection screen displaying clips of 1950s and 1960s films such as Frankenstein Meets the Space Monster, Plan 9 from Outer Space, and Attack of the 50 Foot Woman. The restaurant serves traditional cuisine of the United States. Popcorn functions as a complimentary hors d'oeuvre. Initially, the menu listed items with themed names, such as "Tossed in Space" (garden salad), "The Cheesecake that Ate New York", and "Attack of the Killer Club Sandwich", but these playful names were later altered so that they now describe the dishes in a more standard and straightforward manner. In 1991, the Sci-Fi Dine-In opened along with nineteen other new Walt Disney World attractions marking the complex's twentieth anniversary. By the following year, the Sci-Fi Dine-In was serving upwards of 2,200 people daily during peak periods, making it the park's most popular restaurant. Thai movie theater operator EGV Entertainment opened the EGV Drive-in Cafe in Bangkok in 2003, in a very similar style to the Sci-Fi Dine-In. The Sci-Fi Dine-In has received mixed reviews. USA Today's list of the best restaurants in American amusement parks ranks the Sci-Fi Dine-In fifteenth, but many reviewers rate it more highly for its atmosphere than for its cuisine. Ed Bumgardner of the Winston-Salem Journal wrote that the food is more expensive than it is worth, specifically calling the restaurant's roast beef sandwich both delicious and a ripoff. In their book Vegetarian Walt Disney World and Greater Orlando, Susan Shumaker and Than Saffel call the Sci-Fi Dine-In "the wackiest dining experience in any Disney park".

fWotD Episode 3271: 1986 World Snooker Championship Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles. The featured article for Sunday, 19 April 2026, is 1986 World Snooker Championship. The 1986 World Snooker Championship (also referred to as the 1986 Embassy World Snooker Championship for the purposes of sponsorship) was a professional snooker tournament that took place between 19 April and 5 May 1986 at the Crucible Theatre in Sheffield, England. It was the sixth and final ranking event of the 1985–86 snooker season and the 1986 edition of the World Snooker Championship, first held in 1927. The total prize fund was £350,000 with £70,000 awarded to the winner. The event was sponsored by cigarette manufacturer Embassy. The defending champion was Dennis Taylor, who had won his first world title by defeating Steve Davis 18–17 in the 1985 World Snooker Championship final. In defence of his title, Taylor lost in the first round 6–10 to qualifier Mike Hallett. World number 16, Joe Johnson, defeated Davis 18–12 in the final to win his sole ranking event. Prior to the competition, the bookmakers' odds for a Johnson victory were 150/1. There were 20 century breaks compiled in total during the tournament, the highest of which was a 134 made by Davis in the opening frame of his quarter-final win.

fWotD Episode 3270: Tropical Storm Henri (2003) Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles. The featured article for Saturday, 18 April 2026, is Tropical Storm Henri (2003). Tropical Storm Henri was a moderate tropical storm that struck Florida during the 2003 Atlantic hurricane season. The eighth storm of the season, Henri was one of six tropical cyclones to hit the United States in the year. Henri formed from a tropical wave in the Gulf of Mexico on September 3. Moving generally to the east, it strengthened to reach peak winds of 60 mph (97 km/h) two days later. Henri encountered unfavorable conditions, and it weakened before making landfall on western Florida near Clearwater as a tropical depression. Although Henri degenerated into a remnant low on September 8, the weather system persisted off the east coast of the United States for a few days before moving back ashore over North Carolina. The system brought heavy rainfall across parts of the Mid-Atlantic before dissipating on September 17. Henri caused little damage as a tropical cyclone. In Florida, it dropped heavy rainfall, though damage was limited to minor flooding damage. In Delaware and Pennsylvania, damage was greater, where heavy rainfall damaged hundreds of houses and businesses. The resulting floods in Delaware were described as a 1 in 500 year event. The total damage by Henri along its path amounted to $19.6 million (2003 USD), but no deaths were reported. This recording reflects the Wikipedia text as of 00:40 UTC on Saturday, 18 April 2026.

fWotD Episode 3269: Bridge Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles. The featured article for Friday, 17 April 2026, is Bridge. A bridge is a structure designed to span an obstacle, such as a river or railroad, allowing vehicles, pedestrians, and other loads to pass across. Most bridges consist of a flat deck, supported by beams, arches, or cables. These structures rest on a foundation that is carefully designed to transfer the weight of the bridge to the subsoil without settling. Bridges can be constructed in a wide variety of forms, determined by the location, intended purpose, and available construction technologies. Simple bridge structures include beam bridges made from logs, and suspension bridges made of ropes or vines. The Romans and ancient Chinese built major arch bridges of timber, stone, and brick. During the Renaissance, advances in science and engineering led to wider bridge spans and more elegant designs. Concrete was perfected in the early 19th century, and arch bridges are now built primarily of concrete or steel. With the Industrial Revolution came mass-produced steel, which enabled the creation of more complex forms – including truss and cantilever bridges – that permitted bridges to cross wide rivers or deep valleys. The longest spans use suspension or cable-stayed designs, both of which rely on high-strength steel cables to support the deck. Over time, the maximum achievable span of bridges has steadily increased, reaching 2 kilometers (1.2 miles) in 2022. Other bridge forms include multi-span viaducts, which can cross wide valleys; trestles, a common design for carrying heavy trains; and movable bridges including drawbridges and swing bridges. The design of a bridge must satisfy many requirements, namely connecting to a transportation network, providing adequate clearances, and safely transporting its users. A bridge must be strong enough to support its own weight as well as the weight of the traffic passing over it. It must also tolerate violent, unpredictable stresses imposed by the environment, including winds, floods, and earthquakes. To meet all these goals, bridge engineers typically use limit state design processes and the finite element method. Many bridges are admired for their beauty, and some spectacular bridges serve as iconic landmarks that provide a sense of pride and identity for the local community. In art and literature, bridges are frequently used as metaphors to represent connection or transition. Bridges can create beneficial impacts on a community, including shorter transport times and increased gross domestic product; and also negative effects such as increased pollution and contributions to global warming.

fWotD Episode 3268: Nynetjer Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles. The featured article for Thursday, 16 April 2026, is Nynetjer. Nynetjer (also known as Ninetjer and Banetjer) was the third pharaoh of the Second Dynasty of Egypt during the Early Dynastic Period, prior to the Old Kingdom period. The dates for his reign are uncertain; Egyptologists have proposed that it took place at some point between the late 29th and the early 27th century BC for 35 to 49 years, and most probably lasted around 40 years. Archaeologically, Nynetjer is the best-attested king of the early Second Dynasty and he is also recorded on several king lists dating to the Old Kingdom and the later Ramesside and Ptolemaic periods. There is strong evidence that he succeeded Raneb on the throne. The events at the end of his reign and the identity of his successor are much less clear. Both historical sources and archaeological evidence point to some breakdown or partition of the state along both religious and political lines, most probably seeing concurrent rulers reigning over Upper and Lower Egypt until the country was reunited by Khasekhemwy at the end of the dynasty. Most of the events recorded for Nynetjer's reign on the Palermo Stone, the Old Kingdom royal annals, are regular religious festivals and censuses undertaken for taxation purposes. The probable locations for these events indicate that royal activity was largely confined to the capital Memphis and its vicinity in Lower Egypt, with the possible exception of a military campaign in Nubia. The administrative structure of the state continued on its First Dynasty (c. 3150 – 3000 BC) basis but became more sophisticated, with the earliest evidence for the administrative partition of Egypt into nomes, a regional management system, dating to Nynetjer's reign. Nynetjer had a large gallery tomb dug for himself in Saqqara, now beneath parts of both Djoser's and Unas's pyramid complexes. His tomb comprises a maze of over 150 rooms, some of which are arranged to model a royal palace. Although it was disturbed during Egypt's later periods, the tomb when excavated still housed some of the original funerary equipment of the king. This included hundreds of jars that once held wine, beer and jujube fruits. Excavations have also produced numerous stone tools, some of which seem to have been used in a ritual feast for Nynetjer's burial. The subterranean tomb was probably built with associated superstructures, but these have not survived as they were levelled and overbuilt by subsequent pharaohs.

fWotD Episode 3267: Coeliac disease Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles. The featured article for Wednesday, 15 April 2026, is Coeliac disease. Coeliac disease (Commonwealth English) or celiac disease (American English) is a chronic autoimmune disease, mainly affecting the small intestine. It is caused by an abnormal immune system response to gluten, found in wheat and other grains such as barley and rye. Coeliac disease causes a wide range of symptoms and complications that can affect multiple organs outside the gastrointestinal tract. The classic form of the disease can affect any age group, but is usually diagnosed in early childhood and causes symptoms of malabsorption such as weight loss, diarrhoea, and stunted growth. Non-classic coeliac disease is more commonly seen in adults, characterised by vague abdominal symptoms and complications in organs outside the gastrointestinal tract, such as bone disease, anaemia, and other consequences of nutritional deficiencies. In people with a genetic predisposition to the condition, eating gluten causes inflammation in the small intestine, damaging its lining and leading to malabsorption. The development of coeliac disease is believed to be influenced by other environmental factors, such as infections. Diagnosis is based on symptoms, blood tests, and biopsies of the small intestine. For people who have already cut out gluten, gluten may need to be reintroduced before testing to ensure an accurate diagnosis. The diagnosis is often complicated by the diverse symptoms, overlap with other disorders, and lack of awareness, leading to a delay in diagnosis. Current research indicates that there is not enough evidence to advocate for mass screening for coeliac disease in those without symptoms. The only treatment for coeliac disease is a lifelong gluten-free diet (GFD). A GFD involves removing all food and drink that contains wheat, rye, barley and gluten derivatives. Symptoms can improve within days of adopting a GFD, and the diet can improve quality of life, prevent further complications, and normalise some effects of the disease such as stunted growth. Approximately 1 in 200 to 1 in 50 people have coeliac disease. Diagnoses of coeliac disease have increased recently due to increased awareness and availability of blood testing. The disease is still thought to be underdiagnosed, with a significant number of people with the condition remaining undiagnosed and untreated. The disease usually develops before age 10; it is slightly more common in women than in men. This recording reflects the Wikipedia text as of 01:16 UTC on Wednesday, 15 April 2026.

fWotD Episode 3266: Flow (video game) Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles. The featured article for Tuesday, 14 April 2026, is Flow (video game). Flow (stylized as flOw) is an indie video game created by Jenova Chen and Nicholas Clark. Originally released as a free Flash game in 2006 to accompany Chen's master's thesis, it was reworked into a 2007 PlayStation 3 game by his development studio, Thatgamecompany, with assistance from Santa Monica Studio. SuperVillain Studios developed a PlayStation Portable version of the game in 2008, and PlayStation 4 and PlayStation Vita versions in 2013. In Flow, the player navigates a series of two-dimensional planes with an aquatic microorganism that evolves by consuming other microorganisms. The game's design is based on Chen's research into dynamic difficulty adjustment at the University of Southern California's Interactive Media Division, and on psychologist Mihaly Csikszentmihalyi's theoretical concept of mental immersion or flow. The Flash version of Flow received 100,000 downloads within its first two weeks of release, and had been played over 3.5 million times by 2008. Its PlayStation 3 re-release was the most downloaded game on the PlayStation Network in 2007 and won the Best Downloadable Game award at the 2008 Game Developers Choice Awards. It was nominated for awards by the Academy of Interactive Arts & Sciences and the British Academy of Film and Television Arts. Reviewers praised Flow's visual and audio appeal, but noted the simplicity of its gameplay; several considered it to be more of an art piece than a game.

fWotD Episode 3265: Yuan Shikai coinage Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles. The featured article for Monday, 13 April 2026, is Yuan Shikai coinage. Beginning in 1914, silver coinage featuring a portrait of the Chinese president and military leader Yuan Shikai was minted across the Republic of China to replace the previous imperial coinage and various foreign silver coins in circulation in China. The most prominent and numerous of these coins, the Yuan Shikai dollar (also known as the "fatman dollar" by collectors, from Chinese 袁大头; yuán dàtóu; 'big head Yuan Shikai [dollars]'), remained in production long after Yuan's death in 1916. Designed by Tianjin Mint engraver Luigi Giorgi, the coin features a profile bust of Yuan wearing a military uniform on the obverse, with a wreath of grain and the denomination of one yuan on the reverse. The dollar coins were regularly produced by various mints across China from 1914 to 1928, with a total production run exceeding a billion coins. Until 1920, all coins were dated Republican Year 3 (1914 CE) regardless of their actual year of production. Some mints produced coins featuring various three new dates during the 1920s, but these only incidentally coincided with their production date, with certain dates being usable as mint marks. After the 1926–1928 Northern Expedition, the incipient Nationalist government halted production of the coins in favor of the memento dollar. However, regional circulation and production of the coins continued, with poorer-quality examples produced in Gansu and Communist-held areas during the 1930s. Production was curtailed by the abandonment of the silver standard in 1935, but returned in response to hyperinflation during the Chinese Civil War, including a large run of coins at Canton in 1949. The People's Republic once again produced the coin in the mid-1950s for circulation in newly annexed Tibet and rural regions of southwestern China. In total, around 1.1 billion Yuan Shikai dollars were produced from 1914 and 1954, not including local issues produced by warlords or revolutionaries.

fWotD Episode 3264: Henry Darger Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles. The featured article for Sunday, 12 April 2026, is Henry Darger. Henry Joseph Darger Jr. ( DAR-ghər; April 12, 1892 – April 13, 1973) was an American janitor and hospital worker who became known after his death for his immense body of art and literature. Darger was raised by his disabled father in Chicago. Frequently in fights, he was put into a charity home as his father's health declined, and in 1904 was sent to a children's asylum in Lincoln, Illinois, officially due to his masturbation. He began making escape attempts after his father's death in 1908, and in 1910 was able to escape, walking much of the way to Chicago. As an adult he did menial jobs for several hospitals, interrupted by a brief stint in the U. S. Army during World War I. He spent much of his life in poverty and in later life was a recluse in his apartment. A devout Catholic, Darger attended Mass multiple times each day and collected religious memorabilia. Retiring in 1963 due to chronic pain, he was moved into a charity nursing home in late 1972, shortly before his death. During this move, his landlords Kiyoko and Nathan Lerner discovered his artwork and writings, which he had kept secret over decades of work. From around the early 1910s to the late 1930s, Darger wrote the 15,145-page novel In the Realms of the Unreal, centered on a rebellion of child slaves on a fantastical planet. The chief protagonists are the Vivian Girls, who fight to free the children from the enslaving Glandelinians. Inspired by the American Civil War and martyrdom stories, it features lengthy, gruesome descriptions of battles, many ending with the mass killing of rebel children. Between 1912 and 1925, Darger produced collages, often only loosely correlated to the book. Later he made these with watercolors and traced figures taken from popular sources such as magazines and children's books. These paintings grew more elaborate over time, with some of his largest works exceeding 10 feet (3 m) in length. Little girls, often in combat, are a primary focus; for unknown reasons, they are frequently depicted naked and exclusively with male genitalia. Other writings by Darger include a roughly 8,000-page unfinished sequel to In the Realms of the Unreal entitled Further Adventures of the Vivian Girls in Chicago, a decade-long daily weather journal, and The History of My Life—consisting of a 206-page autobiography followed by several thousand pages about the destruction caused by a fictional Illinois tornado. Darger made no efforts to publish his work, and it was unknown to others until shortly before his death. He is frequently associated with the outsider art movement, which encompasses the work of self-taught creators outside the mainstream art community who frequently produce very singular and unusual work. His art was popularized by his former landlords and is now featured in many museum collections, with the largest at the American Folk Art Museum in New York City and the Intuit Art Museum in Chicago. Initial critical analysis of him and his work took a psychoanalytical approach, often focused on his many depictions of nude and brutalized children. Scholars have hypothesized several different psychological conditions Darger may have suffered from. Theories from earlier scholars that he was a pedophile or murderer have been discredited.

fWotD Episode 3263: Relief of Douglas MacArthur Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles. The featured article for Saturday, 11 April 2026, is Relief of Douglas MacArthur. On 11 April 1951, U. S. president Harry S. Truman relieved General of the Army Douglas MacArthur of his commands after MacArthur made public statements that contradicted the administration's policies. MacArthur was a popular hero of World War II who was then commander of United Nations Command forces fighting in the Korean War, and his relief remains a controversial topic in the field of civil–military relations. MacArthur led the Allied forces in the Southwest Pacific during World War II, and after the war was in charge of the occupation of Japan. In the latter role, MacArthur was able to accumulate considerable power over the civil administration of Japan. Eventually, he gained a level of political experience that was unprecedented and yet to be repeated by anyone else actively serving as a flag officer in the U. S. military. After North Korea invaded South Korea in June 1950, starting the Korean War, MacArthur was designated commander of the United Nations forces defending South Korea. He conceived and executed the amphibious assault at Inchon on 15 September 1950, but when he followed up his victory with a full-scale invasion of North Korea, China inflicted a series of defeats, compelling him to withdraw from North Korea. By April 1951, the military situation had stabilized, but MacArthur publicly criticized the administration's policies, leading Truman to have MacArthur relieved of his command. An apolitical military is an American tradition. The principle of civilian control of the military was also ingrained. Civilian control was an issue considering the constitutional division of powers between the president as commander-in-chief, and Congress with its power to raise armies, maintain a navy, and declare war. This was also an era when the rising complexity of military technology led to the creation of a professional military, and American forces were employed overseas in large numbers. The Armed Services Committee and the Foreign Relations Committee of the U. S. Senate held a joint inquiry into the military situation and the circumstances surrounding MacArthur's relief, and concluded that "the removal of General MacArthur was within the constitutional powers of the President but the circumstances were a shock to national pride". In having MacArthur relieved for failing to "respect the authority of the President" by privately communicating with Congress, Truman upheld the president's role as preeminent.

fWotD Episode 3262: Ojos del Salado Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles. The featured article for Friday, 10 April 2026, is Ojos del Salado. Nevado Ojos del Salado is a dormant complex volcano in the Andes on the Argentina–Chile border. It is the highest volcano on Earth and the highest peak in Chile. The upper reaches of Ojos del Salado consist of several overlapping lava domes, lava flows and volcanic craters, with sparse ice cover. The complex extends over an area of 70–160 square kilometres (27–62 mi2) and its highest summit reaches an altitude of 6,893 metres (22,615 ft) above sea level. Numerous other volcanoes rise around Ojos del Salado. Being close to the Arid Diagonal of South America, the mountain has extremely dry conditions, which prevent the formation of substantial glaciers and a permanent snow cover. Despite the arid climate, there is a permanent crater lake about 100 m (330 ft) in diameter at an elevation of 6,480–6,500 metres (21,260–21,330 ft) within the summit crater and east of the main summit. This is the highest lake of any kind in the world. Owing to its altitude and the desiccated climate, the mountain lacks vegetation. Ojos del Salado was volcanically active during the Pleistocene and Holocene, during which it mainly produced lava flows. Activity was in two phases and a depression or caldera formed in the course of its growth. The volcano was also impacted by eruptions of its neighbour to the west, Nevado Tres Cruces. The last eruption occurred around 750 CE; steam emissions observed in November 1993 may have constituted another eruptive event. An international highway between Argentina and Chile crosses north of the mountain. Ojos del Salado can be ascended from both countries; the first ascent was made in 1937 by Jan Alfred Szczepański and Justyn Wojsznis, members of a Polish expedition in the Andes. During the middle of the 20th century there was a debate on whether Ojos del Salado or Aconcagua was the highest mountain in South America, which was eventually resolved in favour of Aconcagua.

fWotD Episode 3261: Constantine (son of Theophilos) Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles. The featured article for Thursday, 9 April 2026, is Constantine (son of Theophilos). Constantine (Greek: Κωνσταντῖνος, romanized: Kōnstantīnos, 820s or 830s – before 836) was an infant prince of the Amorian dynasty who briefly ruled as co-emperor of the Byzantine Empire sometime in the 830s, alongside his father Theophilos. Most information about Constantine's short life and titular reign is unclear, although it is known that he was born sometime in the 820s or 830s and was installed as co-emperor soon after his birth. He died sometime before 836, possibly after falling into a palace cistern. This recording reflects the Wikipedia text as of 00:53 UTC on Thursday, 9 April 2026.

fWotD Episode 3260: Yugoslav submarine Mališan Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles. The featured article for Wednesday, 8 April 2026, is Yugoslav submarine Mališan. Mališan (pennant number: P-901) was a CB-class midget submarine that served in the Yugoslav Navy (Serbo-Croatian: Jugoslavenska ratna mornarica; JRM) from 1953 to 1957. Laid down in 1943 by the Caproni company in Milan as CB-20, she was ordered by the Italian Regia Marina (Royal Navy) during World War II for harbour defence and anti-submarine warfare tasks, but she was incomplete at the time of the Italian surrender in September 1943. The unfinished boat was captured by the Germans and completed by March 1944. Her main armament consisted of two 450-millimetre (17.7 in) external torpedo tubes located on the sides of the hull, and she had a crew of four. Handed over to the navy of the Italian Social Republic – a wartime German puppet state – she was captured by Yugoslav ground forces in the port of Pola at the end of the war. Repaired, she was commissioned by the JRM and used to train submariners as well as patrol boat crews in anti-submarine warfare. Following her brief Yugoslav service she was donated to the Technical Museum in Zagreb in 1959 as a museum ship. The submarine had been on display for almost 50 years before undergoing an extensive internal and external restoration beginning in 2008 with collaboration among the museum, the Maritime Institute, the University of Zagreb and private contractors. The restored submarine was put on public display in April 2010. The decision to revert to its original Italian paint scheme and designation as part of the restoration has been criticised.

fWotD Episode 3259: Interstate 205 (Oregon–Washington) Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles. The featured article for Tuesday, 7 April 2026, is Interstate 205 (Oregon–Washington). Interstate 205 (I-205) is an auxiliary Interstate Highway in the Portland metropolitan area of Oregon and Washington, United States. The north–south freeway serves as a bypass route of I-5 along the east side of Portland, Oregon, and Vancouver, Washington. It intersects several major highways and serves Portland International Airport. The freeway is 37 miles (60 km) long and connects to I-5 at both of its termini: to the south in Tualatin, Oregon, and to the north in Salmon Creek, Washington. I-205 is named the Veterans Memorial Highway and East Portland Freeway No. 64 in Oregon (see Oregon highways and routes). From Oregon City to Vancouver, the corridor is paralleled by a multi-use bicycle and pedestrian trail, as well as portions of the MAX Light Rail system between Clackamas and northeastern Portland. A freeway to serve as an eastern bypass of Portland and Vancouver was conceived in a 1943 plan for the area, and in the 1950s was included in the federal government's preliminary plans for the Interstate Highway System. In 1958, I-205 was assigned as the designation for the eastern bypass; the Oregon state government initially planned it to travel east through Lake Oswego and close to inner neighborhoods of Portland, but protests from several communities led to the route of I-205 being moved further east and south into other areas of Clackamas County. Construction began in 1967 with work on the Abernethy Bridge over the Willamette River, which opened in 1970. By 1972, I-205 was extended west to Tualatin and north to Gladstone, but the Portland section was delayed by opposition from local governments. A six-lane design was chosen as a compromise, which allowed for the freeway to reach Portland in 1977. The Glenn L. Jackson Memorial Bridge, spanning the Columbia River between Portland and Vancouver, opened on December 15, 1982. The bridge connected to the Washington section of I-205, which had been completed in two stages between 1975 and 1976. The remaining 6.6 miles (10.6 km) in Portland opened on March 8, 1983, and two years later, additional ramps were constructed to connect with I-84.

fWotD Episode 3258: Duffield Memorial Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles. The featured article for Monday, 6 April 2026, is Duffield Memorial. The Duffield Memorial is a gravesite monument located in the churchyard of the Church of St Mary in Great Baddow, Essex, England. Designed by Herbert Maryon and installed in 1912, it originally commemorated Marianne Duffield and William Ward Duffield, who died in 1910 and 1912, respectively. A second plaque was added to commemorate their son, William Bartleet Duffield, who died in 1918. In 2022, Historic England designated the work a Grade II listed building, noting it as an unusual example of both Art Nouveau metalwork and churchyard memorial. The memorial is made of riveted sections of bronze sheet metal and comprises edging and a vertical cross. The edging follows the rectangular perimeter of the grave plot, with short pillars at each corner. Within the plot sits the Celtic wheel cross, decorated in relief with leaflike motifs. A curved shaft connects it to the foot, which, like the four-sided base upon which it is mounted, has curved and splayed sides. The plaques commemorating the Duffields are riveted to the base; a medallion, now lost, was once riveted to the centre of the cross. This recording reflects the Wikipedia text as of 00:57 UTC on Monday, 6 April 2026. For the full current version of the article, see Duffield Memorial on Wikipedia.
