Dr. Simeon Zelotus Henry, MD, whose ancestry is unknown (or not traced here), was born at Canada, June 1792.1,2 He died at Troy, Rensselaer Co., New York, 1 January 1852,3,4,5,1 and was buried at Mt. Ida Cemetery, Troy, Rensselaer Co., New York.5

Simeon married Laura Canfield White, daughter of Consider White and Sarah Washburn, at Troy 17 November 1814.6,7

He was of Scottish descent, and was brought or sent at about age 8 (1800) in the care of a grandfather to the United States, probably at or near Troy or Albany, New York. At 16 (1806) he began to study medicine with Dr. [Henry] Downs of Blooming Grove, near Albany. At age 23 (1815) he passed the examination of the Medical Board in Albany, and received the degree of M.D. and was licensed by the Medical Board in Albany, 3 April 1815.

He was appointed surgeon's mate of the 118th infantry regiment (Washington Co., New York) in 1817 and was replaced in 1819 after he had moved to Montreal.

He resided in Lansingburg until 1817 when he removed to Montreal, where he was awarded a diploma from the Royal Commission. He remained there until 1837. During that time occurred the cholera epidemics of 1832 when the streets of Montreal were lined with the dead and dying. Dr. Henry was in charge of the Montreal Barracks and acquitted himself well. After the epidemic he received several letters of credit, and the highest honors were given by the Medical Commission.

He returned to Troy in 1837, principally due to the harsh climate of Montreal. He was licensed by the Rensselaer County Medical Society in 1838, which is the first year his name appears in the Troy, N.Y. city directory."

In the Troy New York directories:
     From 1838-41 Simon Z. Henry, Physician, home at 114 Fourth St.
     1842-43     38 State St.
     1844          115 Fourth St.
     1845-47     136 Fourth St.
     1848-52     4 Clinton Pl.

His obituary states, "he had built up an eminent reputation for medical skill and science, and established a name that for charity, kindness and benevolence of purpose, will not be soon forgotten by the many he has befriended. Oft have we seen him, and since the foul hand of disease has seized upon him, administering to the sick and helpless when remuneration was not even expected by him. He was a man of great firmness of purpose, and allowed judgment and experience to sway him, rather than new and untried theories. This perhaps cause him to be not quite so intimately connected with the medical faculty generally as is usual. yet he was not bigoted in his opinions, but a persons of great reasoning faculties and a very close student up to the time of his illness."

His disease was a cancer on the face which first appeared as a cold-sore on his upper lip in the summer of 1849. It increased very gradually until it was decided to remove it. The operation was performed by Dr. Bontecou, and the wound healed, leaving apparently no traces of it. However, it reappeared about six months later. A second operation had no effect. It gradually increased, extending over his face, until last March or April it was determined to be incurable. "Since then he has suffered all the tortures that man could suffer with disease. Slowly but surely has the vile disease crept on, seeming to avoid the vital parts that his sufferings might be extended. Of large physical organization and iron constitution, he wasted away until but a mere shadow of his former self remained, enduring without a murmur the most intense pain and the horrible thoughts of leaving a large family circle behind him. In all our experience, we know of no case of such mental torture and bodily suffering as was exhibited in the case of the deceased."8,9,10

He died intestate, and administration papers show that he died on or about 1 Jan 1852, a widow, Laura C. Henry, six unamed children, and the estate was worth less than than $50.00.11
