The founder of the Skunk Works, Kelly Johnson, America’s most famous aeronautical engineer, married a girl in the Lockheed accounting department in 1937. When she was dying in 1969, she explained to Kelly that he was too busy to take care of himself, so she had arranged for him to marry his secretary, which he did. When his second wife was dying, she in turn found a third wife for him.
When my mother was dying, she told my father to marry his secretary when she was gone, which is what he did.
