Edward Joseph O'Hare (September 5, 1893 – November 8, 1939), a.k.a. "Easy Eddie", was a lawyer in St. Louis and later in Chicago, where he began working with Al Capone, and later helped federal prosecutors convict Capone of tax evasion. In 1939, a week before Capone was released from Alcatraz, O'Hare was shot to death while driving. He was the father of Medal of Honor recipient Butch O'Hare, for whom O'Hare International Airport is named. Early life in St. Louis Edward Joseph O'Hare, known to friends and family as E.J., was born on September 5, 1893 in St. Louis to first-generation Irish-American parents Patrick Joseph O'Hare and Cecelia Ellen Malloy O'Hare. On June 4, 1912, E.J. O'Hare married Selma Anna Lauth, a native of St. Louis, born on November 13, 1890. She traced her heritage to Germany. E.J. and Selma started their family in an apartment above Selma's father's grocery store in the Soulard neighborhood. They had three children: Edward ("Butch"), born in 1914, Patricia, born in 1919, and Marilyn, born in 1924. E.J. passed the Missouri bar exam in 1923 and joined a law firm. From 1925 O'Hare operated dog tracks in Chicago, Boston and Miami. O'Hare, as a lawyer, represented the inventor Owen P. Smith, high commissioner of the International Greyhound Racing Association, who patented a mechanical running rabbit for use in dog racing. O'Hare's family relocated to a brand-new Holly Hills home in 1930 as a result of his profitable work for Smith; it included a swimming pool and a skating rink. The O'Hare family used to spend the summers at river camps on the Meramec and Gasconade rivers to escape the heat of St. Louis. Butch had received a.22-caliber rifle from E.J. Butch developed his shooting skills by plinking in the river at cans and bottles that were thrown. It was also during this time that E.J. became fascinated with flying, even hitching a ride in Charles Lindbergh's mail plane. O'Hare took his first job as lead pilot of an air mail route operated by Robertson Aircraft Co. of Lambert Field in St Louis. E.J. then flew commercially whenever possible, and he found chances for his teenage son to briefly take the controls. As a result, his son Butch, the later Medal of Honor recipient, best known for his extreme bravery as a U.S. naval aviator in World War II, became a competent marksman and familiar
