In speaking of the mercantile interests of Cleveland as developed by her prominent operators, it is with pleasure we produce a brief notice of Mr. T. S. Beckwith, one of our well known and most successful merchants. He was born in Lyme, CT, Jan. 11, 1821. Until he was fourteen, he remained on the farm with his father, at which time he commenced clerking in a store in Brownville, Jefferson Co., N. Y., and remained four years. He then came to Cleveland and at once engaged as a clerk with Alexander Sacket, who was then carrying on business on Superior Street, precisely where Mr. Beckwith's carpet store now stands. After two years with Mr. Sacket, he went as clerk with P. M. Weddell & Co., in which capacity he served four years, when he was taken into partnership with P. M. Weddell, Dudley Baldwin and W. E. Beckwith, his brother, and in this firm did business in the dry goods line for about four years, when he and his brother, alone, carried on business several years, and finally Mr. Henry Wick became associated with them and another store was started. Both stores were continued about four years, when the firm dissolved, and another formed under the name of Beckwith, Sterling & Co., composed of T. S. Beckwith, F. A. Sterling and G. Clayes. This firm was dissolved after two or three years and the subject of this sketch left the dry goods business and opened the first store for the exclusive sale of carpets in Cleveland. After five or six years, his former partner, F. A. Sterling, again became associated with him. The firm of Beckwith & Sterling existed three years when they admitted two young men in their employ, O. Baker and W. R. Havens. Mr. Beckwith is a thorough business man, quick to form judgment and quick to act upon it. He is among our best financiers, nearly always makes an investment pay. When he was regularly employed as a salesman, he was hard to match, and one great secret of his success as such was his courteous demeanor to all, whether rich or poor, and an industrious effort to please. We recommend those of our young men who desire to succeed in business to study one of the principal keys to T. S. Beckwith's success--a polite attention to all. It will pay. Mr. Beckwith's business has grown with the city, and the profits with it, and although he has only attained to the meridian of life, and in the full enjoyment of mental and physical energy, he has acquired a handsome competency. Besides his mercantile interest, Mr. B. has aided in giving to Cleveland the character of a manufacturing city, having invested largely in the white lead factory of this city, which is under the management of Mr. J. H. Morley, an account of which will be seen in the Manufacturing Department of this work.
