Two intimates of the late President Richard M. Nixon died this past week. They are Dr. Arnold A. Hutschnecker, 102, who for many years (starting in 1951) served as Nixon's psychotherapist and who died Dec. 28, and William P. Rogers, 87, who served as Nixon's secretary of state (from 1969-73) and who died on Tuesday. Hutschnecker, a specialist in psychosomatic illnesses (as well as insomnia, hypertension, impotence and chronic fatigue), was the only mental health professional known to have treated any president. Rogers was one of the few members of the Nixon cabinet not to have been blemished by the Watergate scandal. But he was burdened by another large shadow in the Nixon White House: that of advisor Henry Kissinger, who ended up replacing Rogers after his departure.
