Lionel Pincus, Co-founder of Warburg Pincus

Eschewing his family's garment business, Pincus got a master's in business administration at Columbia and joined the investment firm Ladenburg Thalmann & Company where he became a partner by the age of 29. In 1964 he had set up shop for himself and a couple of years later he merged firms with Eric Warburg. Their investment fund backed companies such as Mattel very early, and Pincus became a leader in the field, helping to found the National Venture Capital Association. He also advised the government on easing federal regulations that allowed pension funds to become substantial investors in private equity and venture capital funds.
