G. C. Kuhlman Car Company

The G. C. Kuhlman Car Company was a leading American manufacturer of streetcars and interurbans in the early 20th century. The company was based in Cleveland, Ohio.
The Kuhlman Car Company was founded in 1892 by Gustav C. Kuhlman (c.1859-1915), his father and three other brothers. It was acquired by the J. G. Brill Company in 1904, but continued building under the Kuhlman name. It was reorganized in 1931 as J. G. Brill of Ohio, but ceased operations completely in 1932. 
Before it closed, as the market for electric streetcars and interurban cars began to contract, Brill gave Kuhlman the additional task of building steel diners.
The company's main clients were railways in Ohio, Michigan, New York, and Illinois, as well as streetcar operating companies in Akron, Detroit, Cleveland and Montreal, Quebec.
