About Quentin Roosevelt
Quentin Roosevelt I (November 19, 1897 – July 14, 1918) was the youngest son of President Theodore Roosevelt and Edith Roosevelt. Inspired by his father and siblings, he joined the United States Army Air Service where he became a pursuit pilot during World War I and shot down one German aircraft. He was killed in aerial combat over France on Bastille Day (July 14), 1918. He is the only child of a U.S. president to have been killed in action. == Early life == === Childhood === Quentin was born in Washington, D.C., on November 19, 1897, the youngest child of Theodore Roosevelt's household, which included half-sister Alice, sister Ethel, and brothers Ted (Theodore III), Kermit, and Archie. He grew up in the White House, which his father entered as president in 1901. An outgoing and mischievous boy, he treated it as his playground. His behavior prompted his mother, Edith, to label him a "fine bad little boy". Among his many adventures with the "White House Gang" (a name assigned by T.R. to Quentin and his friends), he carved a baseball diamond on the White House lawn without permission, defaced official presidential portraits with spitballs, and threw snowballs from the roof at unsuspecting Secret Service guards. He once rode on top of the family elevator with his friend Charlie Taft, son of Secretary of War and future President William Howard Taft.
