Hodgson was born in Latham, Kansas. In 1911 he received the appointment to West Point Military Academy from the eighth Congressional district of Kansas. Throughout his four years at West Point he distinguished himself in academics and graduated eighteenth in the 164 member class of 1915. He was a star football player on the first undefeated Army team of 1914. He also participated on the varsity baseball and basketball teams and broke the then existing Academy records for the high jump and broad jump. Injuries, however, kept both him and his roommate, Dwight D. Eisenhower, from achieving greater fame in athletics. Following West Point, Hodgson attended Army Engineer school in Washington, D.C.. In World War I he joined the 11th Division with the 211th Engineers but not soon enough to travel overseas. Tours on the West Coast and Washington, D. C. followed by graduation from the Command and General Staff School at Fort Leavenworth seemed to be preparing him for new opportunities. Illness struck him in 1941 and, after several months in Fitzsimmons General Hospital, Hodgson was discharged because of arthritis, a disease which afflicted him since his West Point days.
While attending West Point, Hodgson and Eisenhower shared a room for almost 4 years. Upon being assigned together as roommates, Hodgson told his mother on July 30, 1911, "My room mate is Dwight Eisenhower of Abilene, Kansas.…". While discussing Hodgson in December 1942, then General, Eisenhower stated, "The four years we spent in the same room more than a quarter of a century ago are still one of my most treasured memories." While Hodgson was talking with Eisenhower about running in the 1948 US Presidential Election, he said to Ike, "I think you’d make an excellent President, but am not sure you’d be very happy doing it". Ike eventually did run, and win the 1952 Election. Hodgson spent his last days in the Letterman Hospital, and sent his last letter to Ike August 1955. Hodgson died on October 7, 1955. Upon hearing of his friend P.A.'s death, Eisenhower replied, "In P.A.’s passing, I have lost one of my oldest and best friends; one who always had my admiration, respect, and deep affection. I shall miss him more than I can say".
Legacy
In February 1970, Hodgson's surviving brother and sister, Roy C. Hodgson and Grace M. Wright, donated approximately 200 pages of their brother's letters to the Dwight D. Eisenhower Presidential Library.
