Dr. Charles P. Waite, 76, a former Washington physician, died Saturday in his home in Madison, Neb., after a stroke.

Dr. Waite was a native of Washington and a graduate of Eastern High School. He earned both bachelor's and medical degrees at Georgetown University.

He worked as a researcher on silicosis, a respiratory ailment caused by the inhalation of quartz dust, for the Public Health Service in Pennsylvania and Oklahoma before returning to Washington in 1931.

During the 1930s, he maintained a private practice in general medicine first in Anacostia and then in American University Park. He also worked as medical director at the Government Printing Office during the late 1930s.

Dr. Waite served with the Army in Europe during World War II and was a member of the medical team at the Potsdam Conference.

Following the war, he practiced medicine in Saint Michaels, Md., before moving to Nebraska in 1958. He became a board certified psychiatrist in 1962.

His first wife, the former Evelyn M. Lang, died.

He is survivied by his second wife, Laverna, of the home in Madison; a son, retiried Navy Rear Adm. Charles L., of Potomac; a daughter, Nancy R. Arnall, of Severna Park, and eight grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Regional Mental Health Association in Norfolk, Neb.
