In high school, he was active in forensics, golf, and swimming. Walter carried these interests to Princeton, where he majored in chemistry, won numerals in golf and a “P” senior year when he was captain of the golf team.
He left Princeton in 1943 to enter Johns Hopkins Medical School, and practiced medicine as a surgeon for four decades. He also volunteered at medical clinics in Los Angeles and on the Navajo reservation in New Mexico.
His passion for golf lasted into his 90s, and he won many championships.
Walter is survived by his wife of 55 years, Gail; and his children, Wally and his wife Marie, Neal, Brad and his wife Elizabeth, Jeff and his wife Susan, and Katie; grandchildren Jack, Zachary, Kendall, and Maria; and step-grandchildren Spencer, Lex, and Satchel.
