D., at No. 63 East Leonard street, Grand Rapids, Mich., is a native of Port Dover, Ontario, Canada, was born February 24, 1874, and is a son of Calvin J. and Anna Maria (Hoffman) Chamberlin, natives, respectively, of Canada and Buffalo, N.Y., and married in Port Dover. The father's ancestors were of English and the mother's of German origin, but both trace their American antecedents back to the sixteenth century. The children born to Calvin J. Chamberlin and wife are three in number, and of these the doctor is the eldest; Edwin J., the second born, is now twenty-one years old, is a dental student, and Albert H., aged nineteen, is in the employ of R. G. Dun & Co., commercial agents at Boston, Mass. Calvin J. Chamberlin was engaged in merchandizing in Port Dover for several years, and came to the United States about 1880, bringing with him his wife and children, and for seven or eight years resided in Streator, Ill.; about 1887 he settled in Grand Rapids, where he engaged in the lunber business, and died April 30, 1899, his remains being buried in Valley City cemetery.

Dr. Louis H. Chamberlin acquired his elementary education in Port Dover, Ontario, and Streator, Ill., and finished his literary studies at the Grand Rapids city high school. He next took up the study of pharmacy, and for three years had charge of Peck Bros.' prescription department, as he had been "registered by examination," and later was in the employ of several other large drug firms in this city. In 1894 he began the study of medicine in the office of Dr. E. J. Edwards, and after due preparation entered the Detroit college of Medicine in the spring of 1895, graduating in 1898. During his stay at the Detroit college he for one year assisted Prof. Steinbecker in his practice, and in May 1898, settled for permanent practice in Grand Rapids.

The doctor, beside his office on East Leonard street, has another at the corner of East Fulton and Sheldon streets, where he spends a portion of each day, while his residence is at No. 234 West Broadway. He is instructor of bacteriology in the Grand Rapids Medical college, is a member of the American Medical association, and has been rapidly advancing in the esteem of his fellow-practitioners as well as that of the public. Fraternally, he is a member of the Independent Order of Foresters and of the Order of Maccabees; in religion he affiliates with the Presbyterian church, and in politics is a republican. He is a still unmarried, and in society circles is a general favorite.
