In 1861, the Harris School on Adams Street at the corner of Victory Road (formerly Mill Street) was erected and named in honor of the Rev. Thaddeus Mason Harris who was the pastor of the First Parish for many years. The property was sold to the Boston Housing Authority (in the 1970s?) for the construction of apartment buildings. At times the school was called the School on the Lower Road. The building was designed by architect Luther Briggs, Jr.

Luther Briggs, Jr., born at Pembroke, Massachusetts, in 1822, worked in the Boston office of the well-known architect and engineer, Captain Alexander Parris, whose wife was Luther’s aunt. Young Briggs left the Parris office about 1842 and went to work as a draftsman for Gridley J. F. Bryant, who would later establish his reputation among Boston’s commercial architects. Briggs lived in Dorchester and his suburban architecture was very influenced by the picturesque styles and ornamental landscape designs featured in the books of Andrew Jackson Downing. He designed a variety of structures, including modest dwellings, business blocks, monuments, and public buildings.
