Dan Tyler Moore

Dan Tyler Moore (February 9, 1877 – April 15, 1941) was a career U.S. Army officer and an aide to President Theodore Roosevelt. He was also a cousin of the First Lady, Edith Roosevelt. An avid amateur boxer, and a sparring partner for Roosevelt, he struck the President in the eye, causing him to lose much of the sight of that eye.

Early life Daniel Tyler Moore was born in Montgomery, Alabama, on February 9, 1877, to Mary L. Moore, née Tyler and U.S. Army Captain Alexander Moore. He was named after his maternal grandfather, Brigadier General Daniel Tyler, and he was also the great-great-nephew of Vice President Aaron Burr. He grew up in Hanover, Germany, and was educated in Switzerland. In 1898, he graduated from the Eidgenössische Polytechnische Schule in Zurich, two classes ahead of Albert Einstein. While serving in that capacity, he served as a sparring partner for Roosevelt, who was an enthusiastic amateur boxer. Moore stated, "But could you ask for any better proof of the man's sportsmanship than the fact that he never told me what I had done to him?"

Following his return to the United States, in 1911, Captain Moore was sent to Fort Sill, Oklahoma, where he was to found the U.S. Army School of Fire (today the Field Artillery School). He was given complete authority to design the training of Army privates, non-commissioned officers, and officers at the school, which was initially run on a shoestring. He remained at the school until late 1914. After Butler's death in 1915, Moore married Maria Christina Crespi the following year. His children include author Dan Tyler Moore Jr., and four daughters, including Luvie Moore Abell, wife of The Washington Post columnist Drew Pearson. He is buried in the National Cemetery at Fort Sam Houston, Texas.
