Donald H. Rumsfeld, who resigned as secretary of defense in late 2006, will write his memoirs for the Sentinel imprint of Penguin Group USA. Mr. Rumsfeld, 75, will cover not only his years in the Bush administration but also his experiences with Presidents Richard M. Nixon, Gerald R. Ford and Ronald Reagan; his work in the private sector; and his early life. In contrast to other recent political figures who have produced memoirs, Mr. Rumsfeld is forgoing an advance and will donate profits to a nonprofit foundation he recently established to make educational grants to young people interested in public service and establishing links between the United States and Central Asia.
