Smith Darwin Boughnere, M.D., D. D. S., principal and proprietor of the Valley City Post graduate Dental school, No. Monroe street, Grand Rapids, Mich., is a native of France and was born in Paris, August 3, 1857. He was brought to America in his infancy by his parents, Martin and Mary Elizabeth Boughnere, who located in Norfolk county, Ontario, but later settled in Michigan. In early manhood the father was a hotel-keeper, but later became a farmer, and is now a resident of Portland, Mich., at the age of eighty years. An only brother of the doctor, named Henry P., formerly a dentist, is also a resident of Portland and is engaged in manufacturing. Dr. S. Darwin Boughnere passed his childhood and early manhood in Ontario and about 1879 came to Michigan, but has since traveled extensively, visiting Missouri, California, and other parts of the west. He commenced the study of dentistry at the United States Dental college, Chicago, in 1890-91, but had continued his studies at the Delavan Dental college, at Delavan, Wis., until 1889, receiving diplomas from both institutions, and in 1896 graduated from Kansas City college of Dental Surgery, where he had been demonstrator in 1895-96. He next took post-graduate course in the Chicago college of Dental Surgery, and also graduated from the Physico-Medical college of Chicago, in 1897, with the degree of M. D., and in this institution has also held the position of demonstrator in the dental department. In 1897 he also took a post-graduate course at the Kansas City college of Dental Surgery, and this concluded his college studies. For the twelve years last past, the doctor has been in active practice in Grand Rapids, excepting only such as he passed, during this period, as a student or demonstrator elsewhere. He has expended a small fortune in qualifying himself for his profession, and is beyond doubt one of the most profound students of his art in the state of Michigan. His travel has familiarized him with the best methods employed in the science, anywhere and everywhere, and he has secured a fine cabinet of curios from all parts of the country, principally such appliances as show what the progress of dentistry has been since it first became a recognized science, and in the anatomical selection are many specimens of abnormal growth of jaws and teeth. In addition to his profession ability, Dr. Boughnere is a mechanical genius, and has invented various machines and appliances adapted to the dental profession, which not only simplify but expedite the work. For example: The Boughnere dental engine has a lathe head attachment, twenty-ball bearing, and weighs about sixteen pounds, and may all except the driving wheel be carried in an overcoat pocket, while the wheel is carried in the hand. He has a dental bracket, with attachment, gasoline generator and blow-pipe all complete. This machine, which he alone manufactures, is sold ‘complete for $30, with the exception of the top,’ as it is made adjustable to any top in the market, of which the purchaser may make his choice. The doctor’s operating room is furnished with one of the most complete chairs known to the profession, and his laboratory with complete system of electric power, all of which he has supplied himself regardless of cost; and he has associated with him as his assistant, Dr. R. G. Beckwith, a practical mechanics and dentist. Dr. Boughnere is a genial and affable gentlemen, as well as scientist, and is a typical representative of his race, although reared in America. He was married in Simcoe, Ontario, in 1861, to Miss Alice Dennis, a native of Berkshire, England, and this union has been crowned with one child, Belle, a graduate of the Grand Rapids High School, and, like her mother, a highly educated lady and an ornament to society. In religion the doctor is not connected with any church, and in politics he is independent. His social relations, however, like those of his wife and daughter, are with the elite of Grand Rapids.
