forming the Edward P. Allis Company. Leffingwell said, "He set out to hire known experts: George Hinkley, who perfected the band saw; William Gray, who revolutionized the flour-milling process through roller milling; and Edwin Reynolds, who ran the Corliss Steam Engine works." Allis died in 1889, but under his sons (Charles Allis and William Allis) and the other principals, the firm continued to prosper, and by 1900 it had grown to become one of America's largest steam engine builders. Thomas Chalmers was a Scottish immigrant to America who came to the U.S. about 1842. By 1844 he was at Chicago, Illinois and had found work with P.W. Gates, whose foundry and blacksmithing shops produced plows, wagons, and flour-milling equipment. The Gates firm "built the first steam-operated sawmill in the country at a time when Chicago was the leading producer of milled lumber in the country." In 1872, Thomas Chalmers founded the Fraser & Chalmers firm to manufacture mining machinery, boilers, and pumps. By 1880 steam engines were part of the product line and by 1890, the firm had become one of the world's largest manufacturers of mining equipment. Thomas Chalmers's son, William James Chalmers, was president of the company from circa 1890 to 1901. Meanwhile, the Gates Iron Works, with Chalmers family involvement, had become a manufacturer of crushers, pulverizers, and other rock and cement milling equipment. Another Scottish immigrant family, the Dickson family, came to Canada and the U.S. in the 1830s. By 1852, they had organized a small machine shop and foundry (Dickson & Company) in Scranton, Pennsylvania. In 1856 Thomas Dickson became its president, and in 1862 the firm incorporated as the Dickson Manufacturing Company. By 1900 they were building boilers, steam engines, locomotives, internal combustion engines, blowers, and air compressors. By 1901 the principals of the Edward P. Allis, Fraser & Chalmers, and Gates firms had decided to merge their companies. Edwin Reynolds believed Allis could control the industrial engine business. In May 1901 the Allis-Chalmers Company was formed. It acquired Dickson's industrial engine business. Dickson's locomotive business was rolled into the new locomotive consolidation, the American Locomotive Company (ALCO). 1901–1911 The managing director of the new company was Charles Allis, his brother William was chairman of the board, and William J. Chalmers was deputy managing director. Shortly after the merger was completed, a new factory was built in an area west of Milwaukee that was
