Dwight David Eisenhower II, commonly known as David Eisenhower, is an American author, public policy fellow, television host, writer, lawyer, and former presidential advisor. Born on March 31, 1948, he is the grandson of President Dwight D. Eisenhower and First Lady Mamie Eisenhower. He married Julie Nixon, the younger daughter of President Richard Nixon and First Lady Pat Nixon, on December 22, 1968, making him the son-in-law of the Nixon family. Eisenhower's early life was shaped by his family's prominent political legacy, growing up in the shadow of his grandfather's presidency and military service.

Eisenhower pursued a career that blended public service, law, and media. He served as an officer in the United States Army from 1970 to 1972. After his military service, he attended law school and became a lawyer. During the Nixon administration, he advised on domestic policy matters. In his later career, Eisenhower has focused on writing and public policy, authoring books on American history and politics, such as 'Eisenhower at War' and works related to his grandfather's legacy. He has also appeared as a television commentator and host, providing analysis on historical and political topics.

His connections to two U.S. presidential families have positioned him as a unique voice in discussions of 20th-century American politics, though he has largely stayed out of elected office. Eisenhower has been involved in educational and advisory roles, including as a fellow at institutions focused on public policy.
