The German-born American mathematician and electrical engineer Charles Proteus Steinmetz (1865-1923), by devoting himself to industrial research, made fundamental contributions to the development of both electricity and the industrial laboratory.

Charles Steinmetz was born Karl August Rudolf Steinmetz on April 9, 1865, in Breslau. His father worked for the government railway service, and Karl was encouraged to attend the university and pursue his intellectual curiosities. He had been deformed since birth and had lost his mother at the age of one year but found solace and excitement in the affairs of the mind. He entered the university at Breslau in 1883 and specialized in mathematics and the physical sciences. He also read widely in economics and politics, and in 1884 he associated himself with the Socialist party in Breslau. As he pursued his scientific education, he also continued his political activities, a pattern he was to continue throughout his life.
