At that time, a friend "Swede" Hazlet was applying to the Naval Academy and urged Dwight to apply to the school, since no tuition was required. Eisenhower requested consideration for either Annapolis or West Point with his U.S. Senator, Joseph L. Bristow. Though Eisenhower was among the winners of the entrance-exam competition, he was beyond the age limit for the Naval Academy. He then accepted an appointment to West Point in 1911.
