Frank Rosenthal

A Chicago mobster, Frank Rosenthal arrived in Las Vegas on the order of his boss, Al Capone. In Vegas, Rosenthal oversaw the functioning of many highly successful casinos and is well-known for instituting the first set of bookmakers and venturing into sports betting, something that Vegas is well known for today. Soon after, however, the authorities made his connection to the mob, and he was prohibited from entering, let alone managing, any casino in Las Vegas. Since then, little is known about Frank Rosenthal. Presumably, however, it was believed that he ran many casinos using proxies until his death in 2008.
