One of the city's most famous sons was World War I flying ace and Victoria Cross winner, William Avery "Billy" Bishop, born in Owen Sound, and Canada's leading pilot in the war. He flew with the Royal Flying Corps and Royal Air Force. In 1917 and 1918, Bishop was credited with downing 72 enemy aircraft. He was awarded the Victoria Cross, the Distinguished Service Order and the Military Cross. After the war, he was promoted to Air Marshall and worked as director of recruiting for the Royal Canadian Air Force (RCAF). Bishop is also one of the few to have tangled with Manfred von Richthofen (the Red Baron) and survived, forcing the German pilot to retreat in a damaged aircraft. Bishop later recalled that it was a "close shave, but a wonderful, soul-stirring flight." Bishop's boyhood home, one of the National Historic Sites of Canada, is a museum with artifacts from his life.
