Edwin S. Webster

He was 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.

As a governor appointed chairman of the Commission on Administration and Expenditures, in January 1922, he submitted the commission's Report on State Administration and Expenditures.
