The McGraw Electric Company was a US manufacturer of electric appliances founded by Max McGraw in 1900. It grew through mergers and acquisitions to become a major enterprise. The best known product may have been the Toastmaster pop-up toaster. In 1957 McGraw Electric merged with Thomas A. Edison, Inc. to form McGraw-Edison.
In 1903 McGraw organized the Interstate Supply Company in partnership with his father and four others, selling mill, railroad and electrical equipment. This business grew rapidly. In 1907 McGraw founded the Interstate Electric Manufacturing Company as a branch of the Interstate Supply Company. It became a separate corporation and focused on the manufacture of magnetos, telephones and power switchboards. In 1910 he merged the supply and manufacturing companies into the Interstate Supply and Manufacturing Company. In 1912 McGraw bought the Lehmer Company, a mill supply and electrical equipment manufacturer which he had used as a model for his earlier enterprises. He merged this company and the Interstate Supply and Manufacturing Company into the McGraw Electric Company, taking the position of President. The combined business had sales of more than $2 million that year.
McGraw Electric grew steadily through acquisitions. McGraw used to say, "Never buy a company unless it is making money or seems about to go broke," a philosophy that served him well. In 1938 McGraw built a new plant in Elgin, Illinois, which housed Toastmaster and other product lines. The facility, designed by the architects Olsen and Urbain, cost $250,000 to build. It covered on 25 acres of land beside the Fox River to the south of Elgin. During World War II (1939–45) the plant was used to make anti-aircraft shells and fuses.
As of 1948 the company had plants in Chicago, Elgin and Saint Louis. 1948 sales were $21,000,000 and net income was $2,712,000. In 1949 McGraw acquired the Line Material company of Milwaukee, which manufactured power line equipment. Line Material was based in Milwaukee and operated plants in several other cities. It had 1948 sales of $38,750,000 and net income of $3,108,000. In 1952 McGraw Electric merged with the Pennsylvania Transformer Company. In 1953 the McGraw Electric Company transferred its Toastmaster manufacturing operation to Missouri.
After World War II General Mills began making home appliances such as electric irons, toasters and pressure cookers to maintain employment for workers who had been making supplies for the military. This line never accounted for more than 10% of the output of the Mechanical Division. In May 1954 McGraw Electric purchased the home appliances business from General Mills. By 1955 McGraw Electric had thirty one divisions, with gross annual sales of nearly $300 million. In 1956 McGraw arranged a merger with Thomas A. Edison, Inc. The combined McGraw-Edison Company was launched in January 1957.
