Dr. Wood earned his medical degree at Penn in 1947.
When the Korean War broke out, he was in his second year of psychiatric residency at the Colorado Psychopathic Hospital in Denver.
"Since his class had not repaid the Army by active duty time after medical school," Dr. Wood wrote in his autobiographical notes, "he served two years as an Army psychiatrist."
After being discharged in 1953, he worked at Lankenau Hospital, from which he retired in 1989 as chief of adult psychiatry. He also held sessions during those years at his home office.
Dr. Wood was coauthor of "Psychological Factors in Alcoholic Women" in a 1966 issue of the American Journal of Psychiatry and "Preception in Residency Training: Methods and Problems" in a 1967 issue of the same journal.
The International Association for Plant Taxonomy awarded him its 2006 Engler Silver Medal for his writings about a family of orchids - the Dendrobiums - which Amazon.com reports was published that year by Timber Press.
His son George said that Dr. Wood and his wife, Anne, traveled to all the continents, including Antarctica, as well as the planet's four largest islands - Greenland, Borneo, New Guinea, and Madagascar.
Besides son George and Anne, his wife of 62 years, Dr. Wood is survived by sons H. Page Jr. and M. Wistar III; a daughter, Julia Foster; a brother; and 10 grandchildren.
A memorial was set for 2 p.m. Saturday, Sept. 25, at Haverford Friends Meeting, 855 Buck Lane, Haverford.
