Venture capitalist Laurance S. Rockefeller (1910–2004) was the fourth of the six children of John D. Rockefeller, Jr. In January 1946 he formed Rockefeller Brothers, Inc., one of the first postwar venture-capital operations, starting with a capitalization of $1.5 million. There were eight partners in all, the five brothers and their sister, Abby, and two non family members Harper Woodward and MIT scientist, Ted Walkowicz.
