WAIN,
MARCUS, M. D., of Waupun, Wis., was born in the town of Reading,
Windsor county, Vt., on June 10th, 1808. He is the son of Nathaniel
Swain, and his mother’s maiden name was Charlotte Sherwin, He completed
his literary studies at Chester Academy in his native county. Conceiving
a love for the study of medicine, he entered, upon the completion of his
academic course, the office of Dr. J. W. Emery, of Reading, as a student
in the year 1828, and afterward received instruction in the office of
Dr. Nathaniel Tolles, of the same town, with whom he continued until he
obtained his degree of Doctor of Medicine. He took his first course of
lectures at the Berkshire Medical College in Pittsfield, Mass.
Subsequently he spent two terms at the Medical Department of Dartmouth
College, from which he graduated in 1833. He then located in Chittenden
county, Vt., and practiced his profession there for over twenty years.
In 1857, attracted by the advantages of the great West to men of
enterprise, he removed to Wisconsin and located at Oshkosh, three years
later fixing his residence permanently at Waupun. At this time he was
led to the investigation of homœopathy, and after careful research into
its merits, and a thorough and practical test of its principles, he was
induced to accept it fully as the system of his choice. He has now
continued in its practice for thirteen years, adding to his fame and his
circle of patrons continually.

     From 1861 to 1865 he
held the position of Physician to the State Prison at Waupun.
