Frank Rosenthal, also known as "Lefty," was a prominent figure in the world of professional sports betting and gambling. Born on June 12, 1929, in Chicago, Illinois, he made a name for himself as an expert oddsmaker and a bookmaker. Rosenthal began his career in the 1960s and quickly became widely recognized for his encyclopedic knowledge of sports and uncanny ability to set accurate betting lines. His keen understanding of the inner workings of the sports betting industry allowed him to amass a fortune through his own gambling enterprises. One of Rosenthal's most notable achievements was his role as the manager of the Stardust Casino in Las Vegas during the 1970s and early 1980s. Under his leadership, the Stardust became the go-to destination for high-stakes gamblers and sports enthusiasts. Rosenthal revolutionized sportsbooks, introducing modern innovations such as large electronic scoreboards and multiple TV screens to display different games simultaneously. While Rosenthal was undoubtedly a hugely influential figure in the gambling world, he was not without controversy. His association with organized crime and close ties to the Chicago Outfit raised eyebrows among law enforcement agencies. Rosenthal's connection to the mob was frequently reported in the media, and he faced several attempts on his life throughout his career. In 1982, Rosenthal was targeted in a car bombing that left him severely injured but miraculously alive. This incident inspired the character Sam "Ace" Rothstein, played by Robert De Niro, in the film "Casino" directed by Martin Scorsese. Despite the challenges and dangers he faced, Frank Rosenthal remained a dominant force in the gambling industry until his retirement in the early 2000s. He left an indelible mark on Las Vegas, helping to shape the city's gambling landscape and establish it as the gambling mecca it is today. Frank Rosenthal's remarkable career and his impact on the world of sports betting continue to be remembered and studied by gambling enthusiasts. His expertise, innovation, and enduring legacy have cemented his place in history as one of the most influential figures in the gambling industry.
