Dan Tyler Moore

In 1907, the Artillery was divided, with separate divisions to deal with field artillery, and shore artillery. Moore remained with the "Redlegs", as the field artillery was known. At the time, only Germany had a workable system of indirect fire (how guns may be trained on a target that cannot be seen). Roosevelt wrote to Kaiser Wilhelm II, calling Moore "my young cousin" and secured his admission to the German artillery school, the first foreigner to attend. Moore spent much of 1909 and 1910 at the school, and was careful to appear to be a lazy but amiable officer, while soaking up all the knowledge he could.^[2] He returned to the United States in April 1910, prolonging his stay in Europe for six weeks so he would qualify as a non-resident for customs fees.^[4]

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.^[2] He was then sent to Washington, where he joined the staff of the Army War College. His houseguest there was Franz von Papen, later Chancellor of Germany during the Weimar Republic (and Vice Chancellor briefly under Hitler)—von Papen had been Moore's roommate in Germany. Unbeknownst to Moore, von Papen was running a spy ring out of Moore's house, for which the German was later expelled from the United States.^[2]

In World War I, Moore, by now a Lieutenant Colonel, commanded a field artillery brigade. Upon his return to the United States in 1919, he resigned from active duty, though he maintained a reserve commission until his death on April 15, 1941.^[2]

In 1906 Moore married Luvie Jones Butler.^[5] After Butler's death in 1915,^[6] Moore married Maria Christina Crespi the following year.^[7] His children include author Dan Tyler Moore Jr., and four daughters, including Luvie Moore Abell, wife of The Washington Post columnist Drew Pearson.^[8][3] He is buried in the National Cemetery at Fort Sam Houston, Texas.^[2]
