In 1951, Hubbard's wife Sara went to a psychiatrist to obtain advice about his increasingly violent and irrational behaviour, and was told that he probably needed to be institutionalized and that she was in serious danger. She gave Hubbard an ultimatum: get treatment or she would leave with the baby. He was furious and threatened to kill their daughter Alexis rather than let Northrup care for her. Sara later recalled: "He didn't want her to be brought up by me because I was in league with the doctors. He thought I had thrown in with the psychiatrists, with the devils."Wright, p. 71
