WASHINGTON (AP) Former Secretary of State George P. Shultz, a titan of American academia, business and diplomacy who spent most of the 1980s trying to improve Cold War relations with the Soviet Union and forging a course for peace in the Middle East, has died. He was 100.

Schultz died Saturday at his home on the campus of Stanford University, where he was a distinguished fellow at the Hoover Institution, a think tank, and professor emeritus at Stanfords Graduate School of Business.

The Hoover Institution announced Schultzs death on Sunday. A cause of death was not provided.
