Built by Seth Russell in 1796, the house at 66 Bridge Street in Northampton is part of Historic Northampton’s complex of buildings. It is known as the Shepherd House because Susan Monroe Shepherd purchased it in 1856 and lived there with her husband, Henry Shepherd. Their son, Thomas Monroe Shepherd (1856-1923), left the house to the Historical Society, now called Historic Northampton. The late colonial-style house was much altered over the years by its various owners. The Gothic-style front porch was added in 1840 and the columned porch on the west side was added in 1899. The house is now rented as the headquarters of the Massachusetts Foundation for the Humanities.
