Harold Paine served as Mitchell's deputy and became chief designer after Mitchell died in 1937. Supermarine removed him in 1939 because his wife of many years was German-born, despite roughly two decades of work at the leading edge of British aircraft development. Joseph Smith replaced him and directed the Spitfire family's wartime development. The decision may have cost Supermarine substantial expertise at the opening of the war. Paine then largely disappeared from the familiar succession story, showing how personnel security and institutional memory affected the credit later assigned for famous aircraft.
