Born in 1881 in West Prussia, his family emigrated to the United States when he was eight years old. Growing up in Cincinnati, Ohio, he enlisted as a Private in the United States Army during the Spanish American War, and served in Cuba, quickly rising to the rank of Sergeant. In 1901, the Army sent him to the Philippines, and where he earned a promotion to 2nd Lieutenant in the 30th Infantry. Showing remarkable leadership ability, he moved up in the officer ranks quickly, attending Army Staff College in 1907, and joined the United States Expedition into Mexico in 1916.
