Wiley and edited by Winfield Scott Garner, Gresham Publishing Company, Philadel- phia, PA, 1893, pp. 342-3. "ADOLPHUS BONZANO, a well known civil engineer of the United States, and a member of the great bridge building company of Phoenixville, was born Decem- ber 5, 1830, in the city of Ehingen, kingdom of Wurtemberg, Germany. He early received a classical as well as polytechnical education, and arrived at New York city in September, 1850. He then went to Philadelphia, where, from October until May, 1851, he was engaged in the study of the English language. From May, 1851, to 1855, he was at the American Machine works, at Springfield, Massachusetts, where and at which time he learned the mach- inist business in all its important branches. During the year 1855 he was engaged in erecting machinery in the southern States, and then went to Detroit, Michigan, where he resided until 1868. "Adolphus Bonzano was engaged until 1860 as superintendent of machine shops, and then as designer and superintendent of bridge construction. In 1868 he removed to Phoenixville, Pennsylvania, for the purpose of carrying on iron bridge building, as a member of the firm of Clarke, Reeves & Co., and had charge of the estimates, general plans, and details of construction. This company constructed an immense number of iron bridges, iron viaducts and roofs, amounting, up to December, 1880, to four hundred million pounds in weight. "Among the principal works executed by this firm are: the Girard avenue bridge, at Philadelphia; the Hudson river bridge, at Albany; the bridges for the inter-colonial railway, Canada, and for the North Shore railway, Canada; the elevated railway in the Second, Sixth, Eighth, and Ninth avenues, New York city; and the Susquehanna bridge at Havre de Grace, Maryland. This company, known as the Phoenix Bridge Company, had its principal office at No. 410 Walnut street, Philadelphia, and its works at Phoenixville. The firm was composed of Thomas C. Clarke, Adolphus Bonzano, and John Griffin, and continued in existence until 1884. Since 1884 Mr. Bonzano has been engaged as vice president and chief engineer of the Phoenix Bridge Company, which is the successor of Clarke, Reeves & Co. Since the organization of the Phoenix Bridge Company some very large iron structures have been com- pleted, notably the large double track bridge over the Ohio river at Cin- cinnati, and the great iron viaduct over the Pecos river in Texas, for the Southern Pacific Railroad Company. "Mr. Bonzano is a member of the American Society of Civil Engineers, the American Society of Mining Engineers, and the American Society of Mechanical Engineers. He is a thirty-second degree Mason, a Knight Templar, and a member of the Philadelphia Consistory. "In politics, Mr. Bonzano is a republican, but he takes no decided part in political affairs, as his time is given to the duties of his profession and the needs of his business interests. His native talent, strong indi- viduality, and untiring industry are the means by which he has won his way into the front rank of civil engineering, while the large and substantial bridges which he has erected in the United States and Canada are but so many enduring and conspicuous monuments of his skill and success."
