About Hamilton Coolidge


Hamilton Coolidge (September 1, 1895 – October 27, 1918), was an American pursuit pilot, flying ace in World War I, and recipient of the Distinguished Service Cross.

Coolidge was the great-great-great grandson of U.S. President Thomas Jefferson and the best friend of Quentin Roosevelt, the youngest son of President Theodore Roosevelt. Ham Coolidge and Quentin Roosevelt attended the Groton School together, attended Harvard together, and served together in the U.S. Army Air Service First Pursuit Group in France. They were both killed in action within a few months of each other in 1918.

Coolidge dropped out of Harvard College during his senior year to join the U.S. Army Air Service. He was one of ten Harvard undergraduates accepted from a field of forty applicants for training at the Curtiss Flying School in Buffalo, New York in July 1916.

A private with the Aviation Section, U.S. Signal Corps, stationed in Miami, Florida when the United States entered the war, Coolidge was sent the School of Military Aeronautics at the Massachusetts Institute of Technology on June 5, 1917. He embarked for France on July 23, 1917 and was commissioned first lieutenant on September 29, 1917. After serving as a test pilot at Issoudun he was assigned to the 94th Aero Squadron, commanded by Eddie Rickenbacker, on June 16, 1918. He was promoted to captain on October 3, 1918. On October 27, 1918 he was killed in action, his SPAD S.XIII taking a direct hit from a German anti-aircraft shell near Grandpré, Ardennes. He had eight confirmed "kills" when he was shot down. Like Quentin Roosevelt he was posthumously awarded an A.B. {War Degree} Harvard Class of 1919
