Boynton learned the tinware trade in New Ipswich, New Hampshire and then founded a tinware business in New Hampshire before moving to Templeton, Massachusetts.
Eventually, peddlers with carts sold his tinware housewares throughout New England.
Although he married twice, he had no children and wished to found a school of science where students could help facilitate many of New England's new industries.
With Ichabod Washburn's input, they decided to form a school which combined practical experience and academics.
Boynton donated $100,000 anonymously and died before the first school buildings were completed.
