Major Arteburn Riddle was an American businessperson who owned several casinos in the Las Vegas area. Riddle was born in Louisville, Kentucky. At the age of 11, he moved with his family to Indianapolis. There, he eventually started working in his father's trucking and manufacturing businesses. By 1936, he was involved in an Indianapolis-area nightclub with illegal gambling, which was linked to mobster Al Capone and his Chicago Outfit. In 1940, he became involved with another gambling club in Moline, Illinois. Around this time, he was romantically linked to mob figure Virginia Hill. Riddle moved to Chicago in the 1940s. Riddle made a fortune in the 1930s and 1940s with an oil and gas drilling company in Texas. He also owned a trucking company in Evansville, Indiana from 1937 to 1954. Riddle started his Las Vegascasino career in 1956, when he took over the Dunes. Riddle and his co-investors substantially expanded the hotel using loans from the mob-influenced Teamsterspension fund. He was also noted for booking the first topless showgirl revue in Las Vegas, Minsky's Follies, into the casino. He opened the Silver Nugget casino in North Las Vegas in 1964. Around 1975, he took over the Riata Club and reopened it as the Silver City Casino. In 1977, he took over operation of the Thunderbirdhotel casino and renamed it as the Silver Bird. In 1978, he opened the casino at the Holiday International, under a lease from the hotel. In 1963, Riddle wrote The Weekend Gambler's Handbook, a book of advice for casino gamblers. It became popular, despite containing some advice that was based on superstition rather than mathematics. Riddle's son, Charles, died of suicide in 1966 at the age of 18. Riddle died on July 8, 1980 at Cedars-Sinai Hospital in Los Angeles, from pneumonia after suffering from a rareblood disease. Soon after his death, Riddle's casinos went into bankruptcy. The Silverbird and the Holiday International closed down, and the Silver Nugget and Silver City were sold off. Riddle's estate sold his remaining shares in the Dunes around 1984.
