Perhaps no place of its size can boast of a greater diversity of industries than Fitchburg. In such an article as this attention must necessarily be confined to the chief among them, and but few words devoted to the description of separate establishments. [Illustration: PUTNAM MACHINE COMPANY'S WORKS.] Machinery takes the first rank among the manufactures of Fitchburg. The pioneers in this business here were two brothers, Salmon W. and John Putnam, who, in 1838, established the firm of J. & S.W. Putnam. In 1858 S.W. Putnam organized the Putnam Machine Company, which now has a wide and enviable reputation. Mr. Putnam was President and General Business Manager of the company until his death in 1872. Two of his surviving sons are now actively engaged in carrying on the business, Charles F. Putnam being President and Manager, and Henry O. Putnam Superintendent of the department in which special machinists' and railroad tools are made. There are six other departments devoted to special kinds of manufacture which are superintended by able men. Mr. Putnam's two other sons founded, in 1882, the Putnam Tool Company, located on Walnut street, of which Salmon W. Putnam is President, and George E. Putnam Treasurer, and is owned entirely by the Putnams. This company manufactures machinery, railroad and machine tools. The present location of the Putnam Machine Company, corner of Main and Putnam streets, comprising over twenty-six acres, was purchased in 1866, and the buildings were immediately erected at a cost of over $200,000. The works were built from plans designed by the late President, and are arranged with special reference to the variety of machines manufactured, consisting of railroad and machinists' tools, steam-engines, water-wheels, and shafting. They comprise machine shops, foundries and forges, and rank with the oldest and largest establishments of the kind in the United States. The Putnams are descendants of Gen. Israel Putnam of Revolutionary fame. [Illustration: RESIDENCE OF MRS. SALMON W. PUTNAM, WALNUT STREET] The Fitchburg Machine Works occupy a large and convenient brick building on Main street, near its beginning, and manufacture machinists' tools principally. Opposite is the handsome brick building occupied by C.H. Brown and Company, manufacturers of the "Brown" automatic cut-off steam-engines, which have gained a wide reputation. A little further up on Main street is located the Simonds Manufacturing Company. This company was organized in 1868 with a capital of $150,000 and manufactures machine knives and the well-known "Simonds" Circular Saw.
