According to The New York Times, John S.D. Eisenhower, son of America's 34th president, passed away on Saturday at the age of 91.
John Sheldon Doud Eisenhower was living in Trappe, Md., a community on the state's Eastern Shore about 75 miles away from Baltimore, at the time of his death. A cause was not given for his passing in a statement released by his family.
The official Twitter account of the Eisenhower Library linked to the NYT obituary early Sunday morning, adding that he was an "extraordinary man."
Though being the son of an American president is noteworthy in and of itself, the younger Eisenhower was quite accomplished himself. He graduated from the U.S. Military Academy at West Point (as his father did) in 1944 and served in the U.S. Army for 35 years, rising to the rank of brigadier general.
Eisenhower was part of his father's White House staff and later turned to writing. Beginning with helping Dwight pen post-presidential memoirs, he later moved on to his career as a historian, writing multiple books about military history including The Battle of the Bulge. He also wrote a book about his father titled General Ike: A Personal Reminiscence. In addition to writing, he also served as the 45th U.S. ambassador to Belgium between 1969 and 1971.
Born in 1922, Eisenhower grew us as the only child of Dwight and Mamie Eisenhower after their first child, then three years old, died of scarlet fever the year before. His marriage to Barbara Thompson, by whom he had all four of his children, ended in divorce in 1986. He is survived by second wife Joanne, three daughters, and one son, David, who interestingly enough married Nixon's youngest daughter Julie in 1968.
