Edwin S. Webster

Edwin Sibley Webster (August 26, 1867 – May 10, 1950) was an early electrical engineer and graduate from the Massachusetts Institute of Technology. He co-founded Stone & Webster with his friend Charles A. Stone. He served as President and Vice-Chairman of the company for many years, becoming Chairman on the death of his partner in 1941.
Stone & Webster built their business from a base at Stoughton, Massachusetts into a multi-faceted engineering services company that provided engineering, construction, environmental, and plant operation and maintenance services. They became involved with power generation projects, starting with hydroelectric plants of the late 19th-century that led to building and operating electric streetcar systems in a number of cities across the United States. As well as industrial plants, they built the 50-storey General Electric building in New York City, the Cathedral of Learning at the University of Pittsburgh, a landmark now listed in the National Register of Historic Places, as well as buildings for Massachusetts Institute of Technology. Stone & Webster was the prime contractor for the electromagnetic separation plant for the Manhattan Project at Oak Ridge, Tennessee.
