William Clay Ford, the last surviving grandchild of automotive innovator Henry Ford and owner of the Detroit Lions, has died at the age of 88.
Ford, who served as Ford Motor Company's director emeritus, died at his home on Sunday, the company said in a statement.
Having bought the Lions in 1963 for $US4.5 million ($A4.97 million), Ford would have turned 89 on Saturday.
He was the largest individual shareholder at Ford, serving as a board member and employee for 57 years after joining the company in 1949 after graduating from Yale University.
Ford held various executive and board positions at the company, including chairman of Ford's design committee, chairman of its executive committee and a member of the office of the chief executive.
