Andros B. Stone was born in the town of Charlton, Worcester county, Massachusetts, June 18, 1824. He is the youngest son of Mr. Amasa Stone, (now a hale, old man, ninety years of age, in possession of all his faculties,) and brother of A. Stone, Jr., whose biography has been sketched in an earlier portion of this work. Mr. Stone's boyhood was spent in the various occupations of country farm life, where he received in common with other boys the advantages of a public school education. In his sixteenth year he left home to try the world for himself, and for a year and a half worked industriously at the carpenter's trade with his elder brother, to whom he was apprenticed for four years, to receive thirty-five dollars the first year, forty the second, forty-five the third, and fifty the fourth. An unconquerable desire for a better education forced him to leave this occupation for a time, and enter an academy, the expenses of which he met in part by teaching a public school in the winter season, and which left him only five dollars with which to make another start in the world.

In the meantime, Mr. Stone's brother, to whom he was apprenticed, had been employed by Mr. Howe, the patentee of the "Howe Bridge," and to Andros was assigned the keeping of the time of the workmen, and other similar duties, instead of the more direct labors of the shop. In the autumn of 1842, Mr. Howe purchased Mr. Stone's unexpired time from his brother, advanced his pay, and kept him in the same employment as time-keeper, and adding to this duty that of making estimates, drawing bridge plans, etc., allowing him in the winter an opportunity of increasing his finances by teaching school. Subsequently, Mr. A. Boody and Mr. A. Stone, Jr., purchased the Howe Patent for building bridges in New England, and A. B. Stone, then about nineteen years of age, made an engagement with the new firm. At first he was given the charge of a few men in framing and raising small bridges, but an opportunity soon occurred which enabled him to exhibit his capabilities in a most advantageous light. Messrs. Boody and Stone were constructing a bridge over the rapids of the Connecticut river at Windsor Locks, about fifteen hundred feet in length, in spans of one hundred and eighty feet. One day the superintendent, who had the immediate charge of the work, went to Mr. Stone and complained of being so ill that he was obliged to go home, and desired him to take temporary charge of the men. Mr. Stone alleged his unfitness for the duty of taking charge of so many men at the commencement of so important a work, but as the superintendent said he could not stay longer, Mr. Stone was compelled to assume the responsibility, against his wishes.

On examining the condition of the work the cause of the superintendent's severe illness was made manifest. The lower chords or stringers, of about two hundred and sixty feet in length, had been packed without being placed opposite each other, one being placed several feet too far in one direction, and the other about the same distance in the opposite direction. Here was a dilemma and a difficulty, and an ability in the mind of the young mechanic to meet it, so that, in a very short time, the chords were properly adjusted. He then proceeded with the work, and in three days had nearly completed the first span, when his brother paid a visit of inspection to the bridge. Not finding the regular superintendent in charge, he naturally inquired the cause, and when the circumstances were explained, examined the work very minutely. Without any comments upon what had been done, Mr. Stone left the place, leaving his younger brother in charge, a tacit expression of confidence which was most gratifying, and gave him a self-confidence he had not previously possessed. About this time Mr. Stone was advanced to the general superintendence of construction, which position he retained between two and three years, when his brother admitted him as his partner in the construction of the bridges on the Atlantic & St. Lawrence railroad. A year was successfully spent in the prosecution of this work, when a partnership was formed with Mr. A. Boody for constructing the bridges on the Rutland & Burlington railroad in Vermont, which, although accompanied with grave difficulties, resulted in success.

In 1850, Mr. Stone extended the field of his operations by forming a new partnership with Mr. Maxwell, and purchasing the Howe Patent for building bridges in the three northern New England States. For two years this field was profitably and creditably filled, when, dazzled by the ample resources of the West, New England was abandoned for Illinois. Here another partnership was formed, with his brother-in-law, Mr. Boomer, and under the stimulating effect of an undeveloped country, the new firm of Stone & Boomer soon took a high and honorable rank throughout the entire Western States. The total amount of bridging built by this firm from 1852 to 1858 was not less than thirty thousand feet. They constructed the first bridge across the Mississippi river, the longest span of a wooden truss that had up to that time ever been built. This was done under the most trying circumstances, the thermometer at times marking 30 degrees below zero. The longest draw-bridge of its period was also erected by this firm across the Illinois river, it having a length of two hundred and ninety-two feet, the whole structure revolving on its centre, and capable of being opened by one man in one and one-half minutes. During this time they built the roof of the Union Passenger House, in Chicago, which was of longer span than had hitherto been built. The organization for the carrying on of their work was so complete, that it was a common remark among the engineers of western railroads, "If we want any bridges put up on short notice, we can get them of Stone & Boomer; they have them laid up on shelves, ready for erection!" In connection with their bridge business the firm carried on the manufacture of railroad cars.

In the Spring of 1858, Mr. Stone gave up his home and business in Chicago for his present residence in Cleveland and his present business as an iron manufacturer. After carefully investigating the advantages which Cleveland afforded for such a purpose, and realizing the present and prospective demands for an increased development for the manufacture of iron, Mr. Stone availed himself of the opportunity of identifying his interests with that of the firm of Chisholm & Jones, who at that time had just put in operation a small mill in Newburg. Here at once opened a new and delightful opportunity for Mr. Stone to develope his natural love for the mechanical arts. To manufacture iron required knowledge--was a science, and to be master of his business was both his duty and his pride, and claimed all his unflagging energy, his undaunted courage and determination. Thus the small mill at Newburg grew from the capacity of turning out thirty tons of re-rolled rails to its present capacity of sixty tons, beside the addition of a puddling mill, a merchant bar mill, a wire rod mill, two blast furnaces, spike, nut and bolt works. In the meantime the small beginning had grown into such large proportions, and so many railroad corporations had centered here, that it was thought best to form the same into a stock company, embracing another rolling mill on the lake shore, within the city limits. This was done, Mr. Stone filling the office of President of the Cleveland Rolling Mill Company. In 1868, the Company put into successful operation extensive steel works which they had been engaged in erecting with great care and expense for nearly two years. During that time Mr. Stone had made two visits to Europe for more thorough investigation into the process of making Bessemer steel, and the success of this undertaking so far has been admitted by all who have visited the works to be without parallel in the American manufacture of steel. In addition to this heavy and extended business, Mr. Stone is president of another rolling mill company in Chicago, in which he is largely interested, also of a large coal mining company in Indiana, and vice President of a large iron manufacturing company at Harmony, Indiana, also president of the American Sheet and Boiler Plate Company.

Mr. Stone is eminently known, and justly so, as a mechanic, and is widely known as a man who crowns his thoughts with his acts. Still in the prime of manhood, he stands connected with manufacturing interests, furnishing employment to thousands of men, all of which has been the outgrowth of scarcely more than ten years. This eminent success has not been the result of speculation, or of luck, but the legitimate end of his own hands and brain. Neither can it be said he has had no reverses. At one time the failure of railroad companies left him, not only penniless, but fifty thousand dollars in debt. With an indomitable will he determined to liquidate that debt, and how well he succeeded need not be told. Mr. Stone at present stands at the head of iron manufacturing companies, second to none in the country, possessing almost unlimited credit. This extraordinary success has by no means affected Mr. Stone's modest nature for which he is so noted. Gentlemanly and affable in his intercourse with all ranks and conditions of men, he has won universal respect, and an enviable position in the business interests of our country.

Mr. Stone was married in 1846 to Miss M. Amelia Boomer, daughter of Rev. J. B. Boomer, of Worcester, Massachusetts.
