Civil War Union Army Officer, Medal of Honor Recipient, United States Army General. Born in Massachusetts, he was living in Wisconsin in 1861, and immediately joined the 24th Wisconsin Volunteer Infantry at the outbreak of the Civil War, seeing action at Chickamauga, Stones River, Chattanooga, and the Atlanta Campaign. He was awarded the Medal of Honor in 1890 for his valor at Missionary Ridge, when he seized his unit's colors and planted them on the enemy breastworks, thus rallying the regiment at a critical moment, all while under fire from the Confederates. His unit took the breastworks and eventually won the battle. At the end of the Civil War, he began the study of law, but quickly realized he liked the Army life, and requested a commission. He was commissioned a Second Lieutenant in February 1866. During the next 30 years, he served in Pennsylvania, New York, Utah, Louisiana, and New Mexico, fighting Indians. He was a Lieutenant Colonel in 1898, when the Spanish American War broke out, and he was rapidly promoted to Brigadier General of Volunteers, taking part in the capture of Manila. Immediately after cession of hostilities he was named Military Governor of the Philippines, until replaced by William Howard Taft in 1901. He and Taft never got along, and he was recalled back to the US by President McKinley. In 1905 he was sent to Manchuria to observe the final stages of the Russo-Japanese War, and in 1906, he became Commander of the Pacific Division. In 1906, he was a leading contender for the position of Army Chief of Staff, but President Taft, remembering old arguments, selected another officer. He retired on June 2, 1909. On September 5, 1912, he was in Milwaukee, Wisconsin, addressing a reunion of his old Civil War unit, when he suffered a massive heart attack and died at the dais. He and his wife, Mary Pinkney Hardy, had two children, Douglas and Arthur III. He and his son, Douglas MacArthur, were the only father-son Medal of Honor recipients until President Theodore Roosevelt (father of World War II CMOH recipient Theodore Roosevelt Jr.) was posthumously awarded one in 2001.
