Frank Lawrence "Lefty" Rosenthal (1929-2008) was a Las Vegas, Nevada casino executive with ties to organized crime. Although not licensed by the Gaming Commission, he managed the Stardust, Fremont, Hacienda, and Marina casinos during the 1970s and 1980s. He is also credited with bringing sports bookmaking into casinos and introducing female blackjack dealers. In 1988, he was added to the Nevada Gaming Commission’s Black Book and banned from all Nevada casinos. Robert DeNiro played a fictionalized version of Rosenthal, called "Ace Rothstein," in Martin Scorsese's 1995 film Casino.
