Benjamin "Bugsy" Siegel (February 28, 1906 – June 20, 1947) was an American mobster who was a driving force behind the development of the Las Vegas Strip. Siegel was influential within the Jewish-American mob, along with his childhood friend and fellow gangster Meyer Lansky, the Italian-American Mafia, and the largely Italian-Jewish National Crime Syndicate. Described as "handsome" and "charismatic," Siegel became one of the first front-page celebrity gangsters.
Siegel was one of the founders and leaders of Murder, Inc. and became a bootlegger during American Prohibition. After the Twenty-first Amendment was passed in 1933 repealing Prohibition, he turned to illegal gambling. In 1936, Siegel left New York and moved to California. His time as a mobster during this period was mainly as a hitman and muscle, as he was noted for his prowess with guns and violence. In 1941, Siegel was tried for the murder of friend and fellow mobster Harry Greenberg, who had turned informant; he was acquitted in 1942.
Siegel traveled to Las Vegas, Nevada, where he handled and financed some of the city's original casinos. He assisted developer William R.
