Jackson ability of the family physician. In 1848 he re- ceived the degree of M.D. from the Pennsylvania Medical College and at once settled in Strouds- burg, Pa., as a general practitioner. In 1850 he married Harriet Hollinshead. He volunteered for medical service in the United States Army in 1862 and rose to the post of assistant medical director of the Army of Virginia. That he al- ways retained his interest in military associates is attested by the fact that in 1889 he was elected to the presidency of the acting assistant surgeons of the United States Army. He was discharged in 1864 and in the following year suffered the loss of his wife. In 1867 he made his first tour of Europe and chanced to be in the party of Mark Twain, who immortalized him as the witty and humorous "Doctor" in Innocents Abroad. It is said that the jokes attributed to the "Doctor" Were a verbatim report of Jackson's utterances. For reasons not entirely clear Jackson now made a radical departure in his career and about 1870 moved to Chicago with a view to limiting his practice to gynecology. There was precedent enough for this course, for the pioneer labors of J. Marion Sims [q.v.] and others had made it practicable to restrict one's activities to the new specialty. In 1871, although the Chicago fire of that year must have made the undertaking doubly difficult, Jackson succeeded in founding the Woman's Hospital of Illinois of which he was surgeon in chief, and in the same year he married as his second wife Julia Newell of Janes- ville, Wis., a woman of great talents and social prestige. In 1872 he received an appointment as lecturer on gynecology at Rush Medical College, from which he resigned in 1877. That same year he infected himself while operating and the re- sulting sepsis caused some impairment of his general health. In 1882 he was a cofounder and the first president of the Chicago College of Physicians and Surgeons. By 1883 gynecology had progressed so far in Chicago that a special society was formed, the Chicago Gynecological Society, with Jackson as its president. In 1889 he developed an attack of aphasia, attributed to his infection many years before, and made a tour of the world in company with his wife. Upon his return it is known that he felt himself doomed to an early demise but he plunged into manifold ac- tivities: he was elected president of the Ameri- can Gynecological Society in 1891, and his last year of practice, 1891-92, Was the most lucrative and successful of his career. On Nov. i, 1892, he suffered a second stroke of apoplexy and suc- cumbed on the I2th. He wrote many valuable papers on gynecological subjects, characterized by originality in thought and language, but it is Jackson said that this very quality of originality de- terred him from writing a textbook, because he would be compelled to incorporate the work of other men. Since he was unsurpassed as a teach- er, this attitude was deplored. [R. F. Stone, Biog. of Eminent Am. Physicians and Surgeons (1894); W. B. Atkinson, The Physicians and Surgeons of the U. S.

Two years later, shortly before the birth of Andrew, the father died. Mrs. Jackson, being left a de- pendent widow, took up residence with relatives, and her little son started life under the most dis- couraging circumstances. He was sent to an old- field school, and developed into a tall, slender, sandy-haired, tempestuous stripling. When he had attained the age of nine years, the Revolu- tion broke upon the country and its horrors later visited the Waxhaw' settlement. His brother Hugh was killed in 1779; he and his brother Robert, though mere lads, took part in the bat- tle of Hanging Rock, and afterward were cap- tured by the British. The boy troopers were thrown in prison, where they contracted small- pox. Their mother secured their exchange and release, but Robert died from either the effects of the disease or neglected wounds. During 1781 Mrs. Jackson went to Charleston to nurse the sick, and here she died of prison fever. Bereaved of the last member of his family, Andrew at the age of fourteen was now alone in the world. His mother's death at that place probably drew him to Charleston. Here he learned something of the great world, including the racing of horses and the manners of "gentlemen." Returning to his native settlement, he tried his hand at school- teaching and finally decided to take up the study of law. This was a daring yet a sagacious de- cision. Now seventeen years old, he apparently had no funds with which to finance his studies, but he possessed a horse and an abundance of courage; and the West was in need of young lawyers who could endure the rigors of frontier practice. He began the reading of law under Spruce Macay, at Salisbury, N. C, and had as fellow student and companion John McNairy. 526
