George Rice grew up in the shadow of his uncle, Major Edmund Rice, who earned a Medal of Honor in the Civil War. He was educated at the Mount Vernon Military Academy, Chicago, Illinois, and at Tufts College Divinity School, where he was subsequently ordained as a Universalist Minister. In 1898, he was commissioned as a first lieutenant and an Army Chaplain, and served in the Spanish-American War, and subsequently in the Philippine Insurrection where he was cited for bravery. He also served in World War I. 1925 his earlier citation was upgraded to the Distinguished Service Cross, making him the first military chaplain to receive that high award.
