The most tragic episode of Wiener's life happened in 1951 when he was fifty-seven years old and passionately involved in a collaboration with his friend Warren McCullough and a group of young colleagues that he called "the boys." ... Margaret was insanely jealous of McCullough and his boys, and resolved to break up their friendship with Wiener ... she informed Wiener that McCullough's boys had seduced his daughter Barbara when she was a teenager staying at McCullough's house. This story had no basis in fact, but Wiener believed it ... and immediately wrote an angry letter to the president of MIT dissolving all connection between himself and the McCullough team.
