JACKSON, John Davis, physician, born in Danville, Kentucky, 12 December, 1834; died there, 8 December, 1875. He was graduated at Centre college in 1854, and at the medical department of the University of Pennsylvania in 1857, and began to practise in Danville. He entered the Confederate army as a surgeon, served with the Army of Tennessee during the first year, and subsequently with the Army of Northern Virginia. During this service he made a report on vaccination among the troops, which was published, by order of the surgeon-general, at Richmond. At the close of the war he resumed practice at Danville, and was eminently successful. In 1872 he visited England as a delegate from the American medical association to the British association. In 1873, while engaged in an autopsy, he made an abrasion on his finger, which finally resulted in his death. Dr. Jackson was a member of various medical organizations, and was to deliver the address before the alumni of the University of Pennsylvania at the date of his death. He translated Farabeuf's "Manual on the Ligation of Arteries" (Philadelphia, 1874); and was the author of a biography of Dr. Ephraim McDowell, the first operator for ovariotomy (1873); and various contributions to medical literature.
