Her husband, Phil Graham, was a bright young lawyer who took over at the Post in 1945. The couple became a popular part of the Washington social scene. Behind the facade, however, lay a different story. Phil was given to wild mood swings and abusive behavior that caused Katherine a great deal of mental anguish. He suffered from manic depression, which gradually got worse, culminating in his suicide when Katherine was 46. Suddenly, she found herself in control of the Post.
