"That's why he took time off to get a master's and reapplied to the University of Cincinnati," whose medical school accepted him.
During World War II, he was an Army medical officer from July 1942 to October 1945 and served in the North African campaign and then in Sicily. A military citation states that he earned a Bronze Star "in connection with military operations against the enemy on 5 August 1943 in Sicily."
His daughter read from a more detailed framed document that states that "on the night of 5-6 August 1943, in the vicinity of Troina, Sicily," First Lt. Krull "distinguished himself in the administering of medical care to the wounded men of his battalion."
"Although the aid station was under intense enemy fire, Lt. Krull with complete disregard for his personal safety continuously remained at his post treating the wounded."
The document cited "his coolness and courage while under fire."
While on leave in London during the war, Dr. Krull met Ruth Harr, a Jewish refugee from Germany, and they were married there.
After returning to the United States, he completed his residency at Coney Island (N.Y.) Hospital in 1947 and did postgraduate study of internal medicine in 1948.
He set up a medical practice at his home in Teaneck, from which he made house calls, his daughter said, and later worked at Teaneck Medical Center, which he and other physicians owned.
Dr. Krull retired in 1985 to Wynmoor Village, a retirement community in Coconut Creek, Fla., where he was a member of the amateur radio operators' club.
Besides his daughter, Dr. Krull is survived by a grandson and a granddaughter. His wife died in 2002.
A funeral service was scheduled for 11 a.m. Wednesday, Sept. 11, at Gutterman & Musicant Jewish Funeral Directors, 402 Park Ave., Hackensack, N.J. 07601.
