It is believed that Damon was one of the junior draftsmen in the Town & Davis office in New York, and when in 1811 he was called to Northampton to build the First Congregational Church, it seems probable that Ithiel Town helped prepare the plans.
In Northampton Mr. Damon also designed the Town Hall built in 1823.
In the course of years he executed many important commissions, and the drawings, some of them in India ink, showed skill in draftsmanship. In his work as builder he was one of the first to understand the use of a truss and incorporated it in the bridgework of a number of buildings. Thirteen or more churches in the western part of the state are ascribed to him among which should be named the First Church at Lenox, dating from 1814; the First Church at Springfield, 1818 ; the old Meeting House at Ware, 1820,
and the Unitarian Meeting House at Greenfield. In addition he was architect of the County Court House at Lenox (an early building dating from 1814), and probably designed (at least he was paid for making the plans) the oldest group of buildings at Amherst College, including the North and South Halls and the Chapel between 1821 and 1827.
