John Paul "Jack" Hill, a retired medical equipment salesman, died of a heart attack July 12 at his Charles Village home. He was 57.
Born in Baltimore and raised in Govans, he graduated from City College in 1963 and later attended the University of Maryland.
Mr. Hill sold cardiac X-ray equipment for Toshiba, General Electric and Phillips until two years ago, when ill health caused him to retire. Earlier in his career, he had worked as an X-ray technologist for Johns Hopkins and the Bayview Medical Center.
Mr. Hill was a dog fancier who also trained Arabian horses and spent weekends photographing wildlife on the Eastern Shore. In the 1980s, he was president of the Friends of Wyman Park Dell.
He also enjoyed riding motorcycles and was a fan of Formula One auto racing. In 1998, he completed a cross-country trip with two friends.
A Mass of Christian burial was offered Thursday at SS. Philip and James Roman Catholic Church, where he was a member.
Survivors include his wife of 30 years, the former Elizabeth C. Cieslak; three brothers, Richard Hill of Baltimore, Peter Hill of Leesburg, Va. and Thomas Hill of Columbia; and a sister, Ann Hill DeBarbieri of Gansevoort, N.Y.
