Dee Hock

Dee Ward Hock (born 1929) is the founder and former CEO of the VISA credit card association. In 1968, Hock convinced Bank of America to give up ownership and control of their BankAmericard credit card program. The new company, called National BankAmerica, was a non-stock membership corporation equally owned by its member banks. The name was changed to VISA in 1976.
In May 1984, Hock resigned his management role with Visa, retiring to spend almost 10 years in relative isolation working a 200-acre (0.81 km2) parcel of land to the west of Silicon Valley. He was inducted into Junior Achievement’s U.S. Business Hall of Fame in 1991, and the Money magazine hall of fame in 1992.
