Dee Hock, a banker with a junior college degree who shaped the Visa credit card into a global financial behemoth, died on July 16 at his home in Olympia, Wash. He was 93.
His son David confirmed the death.
The credit card business was in an early, rocky stage of development in 1967, when Mr. Hock was named to run the credit card department of National Bank of Commerce in Seattle, which was licensed by Bank of America to issue its BankAmericard.
