Dwight Eisenhower's military career was approximately 32 years long. It began in 1915 and ended in 1948, when he took over as President of Columbia University. Eisenhower went on to become President of the United States in 1952.
After graduating from West Point in 1915 just after the end of World War I, Lieutenant Eisenhower served in a variety of places across the United States for a number of years. In 1920, however, his career took a major turn when he served as a military aide to General John J. Pershing and then to General Douglas MacArthur in the Philippines.
Eisenhower earned his first star with a promotion to brigadier general just as the United States was about to enter World War II, and went to Washington, D.C., where he worked as a planning officer. After impressing Army Chief of Staff General George C. Marshall, Eisenhower received a series of important command assignments. In 1944, he served as Supreme Commander of Operation Overlord, the Allied assault on Nazi-occupied Europe.
