JONES, John, surgeon, born in Jamaica, New York, in 1729; died in Philadelphia., Pennsylvania, 23 June, 1791. He was a son of Dr. Evan Jones, a Welsh physician, who came to this country in 1728. He was educated professionally at the medical schools and hospitals of London, Paris, Leyden, and Edinburgh, where he became acquainted with the most eminent contemporary professors. On his return, after a long sojourn in Europe, he settled in New York, but in a few years was obliged to revisit London for a brief period for the benefit of his health. Dr. Jones was professor of surgery in King's college from 1767 till 1776, and one of the two original founders of the New York hospital--Dr. Samuel Bard being the other--in 1771. He was one of the ablest surgeons of his time, and especially skilful as an operator in cases of lithetomy. He left New York, on the British occupation of the city, for Philadelphia, after the evacuation of that city by the enemy, and there spent the remainder of his life. In his new home he was highly esteemed, holding several offices of trust and importance connected with his profession. He was honored by the confidence and friendship of Washington and Franklin. On a critical occasion he was sent for to attend the president in New York in 1790, and in the same year attended Franklin in his last illness, of which he has left a detailed and interesting account. Dr. Franklin remembered him in his will as among his personal friends. Dr. Jones was the author of "Plain Remarks upon Wounds and Fractures, designed for the Use of the Young Military Surgeons of America" (New York, 1775; new ed., with a memoir by Dr. James Mease, Philadelphia, 1795).
