James O’Brien attended Saint Joseph’s Parochial School in Alameda, California, and Saint Joseph’s College in Mountain View. Beginning in 1932, he studied for six years at Saint Patrick’s Seminary in Menlo Park. In 1938, he was ordained a Catholic Priest at Saint Mary’s Cathedral for the San Francisco Diocese. He served as assistant pastor of Five Wounds Parish in San Jose from 1938 to 1940. Small of stature, he was initially rejected for military service by the Navy, but was finally accepted by the Army and commissioned in the Army Chaplains Corps. He was assigned as assistant base chaplain at Nichols Field in the Philippine Islands, in 1941, and subsequently became an assistant regimental chaplain for the Provisional Air Corps on Bataan. He was captured after the fall of Bataan, and held as a Prisoner of War of the Japanese. In 1944 he was among a group of prisoners being sent to Japan on the “Hell Ship” Arisan Maru, which was sunk by American submarines on October 24, 1944, and lost at sea.
