Father Aloysius H. Schmitt (December 4, 1909 – December 7, 1941) was a Roman Catholic priest of the Archdiocese of Dubuque, who served as a chaplain in the United States Navy at the beginning of World War II.
Born in St. Lucas, Iowa, Schmitt studied at Columbia College (now Loras College) in Dubuque, Iowa and graduated in 1932. He then studied in Rome for the priesthood. He was ordained on December 8, 1935. Father Schmitt was first assigned as an associate at Saint Mary's Church in Dubuque. He was also assigned to St. Mary's Cathedral in Cheyenne, Wyoming. After four years, he received permission to become a chaplain, and joined the United States Navy. He was appointed Acting Chaplain with rank of Lieutenant, Junior Grade (LTJG) on June 28, 1939.
On December 7, 1941, Fr. Schmitt was serving on board the battleship USS Oklahoma during the Japanese attack on Pearl Harbor, when a hit caused the ship to capsize. A number of sailors, including Fr. Schmitt, were trapped in a compartment with only a small porthole as the means of escape. Fr. Schmitt helped a number of men through this porthole. When it came his time to leave, he declined and helped more men escape. In total, he helped 12 men escape.
