[37] A November wedding date in Denver was moved up to July 1 due to the impending U.S. entry into World War I; Funston approved 10 days of leave for their wedding.[38] The Eisenhowers moved many times during their first 35 years of marriage.[39]
The Eisenhowers had two sons. In late 1917 while he was in charge of training at Fort Oglethorpe in Georgia, his wife Mamie had their first son, Doud Dwight "Icky" Eisenhower (1917–1921), who died of scarlet fever at the age of three.[40] Eisenhower was mostly reluctant to discuss his death.[41] Their second son, John Eisenhower (1922–2013), was born in Denver, Colorado.[42] John served in the United States Army, retired as a brigadier general, became an author and served as U.S. Ambassador to Belgium from 1969 to 1971. Coincidentally, John graduated from West Point on D-Day, June 6, 1944. He married Barbara Jean Thompson on June 10, 1947. John and Barbara had four children: David, Barbara Ann, Susan Elaine and Mary Jean. David, after whom Camp David is named,[43] married Richard Nixon's daughter Julie in 1968.
