The Home Telephone Company of Rochester (NY), one of the largest independent companies at the beginning of the century, gained control in 1902 of the Stromberg-Carlson manufacturing company which consequently transferred its activities from Chicago to Rochester. Once there, the company [Stromberg-Carlson] designed an automatic system at its new local factory and this was often referred to in the technical literature of the 1900s and 1910s as the ROCHESTER system. On the other hand, some publications mention the system under the new name of the American Automatic Telephone Company which had very briefly (1905-1908) been adopted by the company now in Rochester before the economic crisis of 1907 had put an end to its activities under that name . ... `ROCHESTER automatic system: it was a 50-point rotary step-by-step system and its dial had the peculiarity of having 50 figures.
