On the record

Rosenthal was sent for by his father in 1847, landed at Philadelphia, and studied medicine at Oberlin, Ohio, under Dr. Maxwell, completing his course at the medical department of Western Reserve University in 1852. He practiced four years at Bedford, Ohio, and from 1856 at Indianapolis, then settled in Fort Wayne in 1860, when the city held about seven thousand people. For nearly half a century he stood among the foremost surgeons of northern Indiana: president of the Allen County Medical Society for numerous terms, a term as vice-president of the Indiana State Medical Society, eight years on the Fort Wayne board of health, a period as county physician, and for many years head of the staff of physicians and surgeons at St. Joseph Hospital, whose service he helped systematize. He and his wife were prominent in the Achduth Veshalom congregation. On 30 August 1895, at Mackinac Island, he recorded a spoken message to his children — a phonograph "voice from the Unknown Beyond" — which his son Maurice preserved and Griswold prints in full. He married Adele Rauh at Cincinnati on 30 November 1857; she died in 1895.
