"He was photographing the integration of the Army in Frankfurt," his daughter said, "photographing the incoming black soldiers and the outgoing white soldiers."
The photos weren't for publication, she said, but mostly "for the archives from the base."
Mr. Knuttel had been a member of the Marine Corps Reserve after high school graduation, she said, and earned his discharge in 1949.
He chose the Army for his full-time military obligation, from which he was discharged in 1952, she said, because "it let him have a little more leeway in what he was going to do," with his photo training.
He returned to Philadelphia to work as a truck driver for the Coca-Cola Co.
But in the early 1970s, he earned a bachelor's in business administration and accounting at Drexel University, and worked as a comptroller at St. Christopher's through much of that decade.
He chose that career, his daughter said, because "he liked things in a good system and order."
Mr. Knuttel moved to comptroller at Cooney Bros., a distributor of plumbing supplies, then at Fifth and Dauphin Streets, his daughter said.
Finally, after he had relocated his family to Brigantine, he was a comptroller for Baumgardner Construction Co. in Egg Harbor Township, N.J., until he retired in the 1990s.
Besides his daughter, Mr. Knuttel is survived by his wife, Rose; sons John-Tom and Eric; eight grandchildren; and a great-grandchild.
A Funeral Mass was set for 10 a.m. Wednesday, July 30, at St. Thomas Church, 331 Eighth St., Brigantine.
