Frank E. Winsor (1870-1939) was the chief engineer for the Boston Metropolitan District Water Supply Commission, now the Massachusetts Water Resources Authority, from 1926 until his death in 1939 and was closely involved in the design and construction of Winsor Dam and Goodnough Dike which were built by the Commission to create the Quabbin Reservoir in Massachusetts.

[1] Frank Edward Winsor was born November 16, 1870, in Providence, Rhode Island and died on January 30, 1939, a resident of West Newton, Massachusetts, where he had lived for many years at 189 Mt.

From 1903-1915 he worked on projects for New York City including being in charge of the construction of the Kensico and Hillview reservoirs and 32 miles of Catskill Aqueduct.

At the completion ceremonies for the project on September 30, 1926, Providence Mayor Joseph H. Gainer called Winsor "[T]he man to whom most of the credit for this undertaking belongs.

The dams were finished shortly after his death in 1939, but the Quabbin Reservoir did not fill to its maximum holding capacity until 1946.
