Saul Phillip Steinberg (August 13, 1939 – December 7, 2012) was an American businessman and financier renowned for his bold corporate takeover tactics. He founded Leasco Data Processing Equipment Corporation, a computer leasing firm, while still young, using it to orchestrate the audacious 1968 acquisition of the significantly larger Reliance Insurance Company. This deal propelled him to billionaire status before age 40, and he subsequently developed Reliance Group Holdings into a major holding company. Steinberg earned a reputation as a corporate raider through high-profile, though unsuccessful, bids for Chemical Bank in 1969 and Walt Disney Productions in 1984.
