"In the autumn of 1862, he was appointed adjunct professor of Surgery in Dartmouth, and from that time forward his honors, literally, outran his years.
"The number of his appointments to professional chairs in different institutions, is something beyond precedent in the history of any young American practitioner.
"In 1865, he was invited to the chair of Surgery in the University of Vermont, and in the same year to a similar chair in the University of Michigan.
"Both these positions he accepted, and ably filled for several years.
"In 1870, on the resignation of his honored father at the age of threescore and ten, Dr. Ben was at once called to the chair of Surgery in Dartmouth, and entered upon its duties, still continuing to perform full duty in both his other professorships. He also delivered a course of surgical lectures in Bowdoin College, Maine, during the same year.
"In 1871, he received the appointment of Surgical professor in the Long Island Medical College, in the city of Brooklyn, which he accepted, together with the post of visiting surgeon in the hospital to which the college was attached. His work during this period was extremely arduous, but was performed with the utmost ability and credit.
"In 1872, he was invited to a professorship in the New York University, and also to another (that of Surgical Anatomy) in Bellevue Hospital Medical College in New York City. The former of these he declined, but he accepted the latter and retained it until his death.
"In 1873, Dr. Crosby was invited by the Trustees of Jefferson Medical College, Philadelphia, to accept the chair of Anatomy, on the resignation of the distinguished Dr. Pancoast.
"This, though not accepted, may be reckoned the crowning honor in his wreath of professional laurels."
For all the qualities which distinguish the model physician, surgeon, teacher, and companion, few names, in all the annals of Medicine, stand higher than that of Alpheus Benning Crosby.
