Venrock (portmanteau of Venture and Rockefeller) is a venture capital firm formed in 1969 to build upon the successful investing activities of the Rockefeller family that began in the late 1930s. It has offices in Palo Alto, California, New York City, and Boston, Massachusetts.
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. In 1969, the firm became known as Venrock.[1] Laurance S. Rockefeller became an investor in enterprises based on science and technology.
