Background
Jones was born in 1729 in Jamaica, Queens County, New York, United States, of Welsh Quaker stock. He was the son of Dr. Evan Jones and his wife, Mary Stephenson. His grandfather, Dr. Edward Jones, came to Pennsylvania in June 1682, and married Mary Wynne, daughter of Dr. Thomas Wynne who brought his family to Pennsylvania with William Penn on the Welcome later in the same year.
Education
After a course of study at a private school in New York, John Jones went to Philadelphia to begin medical studies under his uncle by marriage, Thomas Cadwalader, but he received most of his education abroad, studying in London under William Hunter and Percival Pott, and in Paris under Petit and Le Dran. He also took courses at Edinburgh and Leyden (then a famous medical center), and finally obtained his degree in 1751 at the University of Rheims, where his graduation thesis (published in New York in 1765) bore the title Observations on Wounds.
Career
After graduation Jones settled in New York, where he soon became known as surgeon and obstetrician. He is said to have been the first American lithotomist, he was certainly a successful one, and his fame soon became diffused throughout the colonies. He never required over three minutes to complete the operation of lithotomy and performed it on occasion in half that time.
At the outbreak of the French and Indian War he at once volunteered as surgeon, and served until the close of hostilities. In 1767, when the medical department of King's College, New York, was organized, he became professor of surgery and obstetrics.
A little later, suffering from asthma, he made a long visit to London, where he improved the time by fraternizing with his former teachers and by attempting to obtain subscriptions for a hospital for New York. In 1770, with Dr. Samuel Bard and others, he petitioned for a charter for the New York Hospital, and when the institution was opened he was made one of the attending physicians. The Revolution and the eventual destruction of the hospital by fire ended this enterprise.
When New York was captured by the British he removed to Philadelphia. Although the frailty of his health kept him from being active in the field, he is given credit for an important share in organizing the medical department of the Continental Army.
Having found the climate of Philadelphia favorable for his asthma, Jones definitely settled there in 1780, and was at once appointed attending physician to the Pennsylvania Hospital and elected president of the Humane Society. He was a personal friend of Washington, whom he attended professionally in 1790, and was the personal physician of Franklin, whom he attended in his last illness.
He published "A Short Account of Dr. Franklin's Last Illness" in the Pennsylvania Gazette and the Freeman's Journal, both of Philadelphia, 1790. When the College of Physicians of Philadelphia was formed in 1787, Jones was its first vice-president, and he contributed a paper, "A Case of Anthrax" (read posthumously), to the first volume of its Transactions (1793). A third edition of his book on wounds and fractures with the title, The Surgical Works of the Late John Jones, was brought out in 1795 by his friend Dr. James Mease.
