Waltham (/ËwÉËlËÎ¸Ã¦m/) is a city in Middlesex County, Massachusetts, United States, and was an early center for the labor movement as well as a major contributor to the American Industrial Revolution.
The Mills of Francis Cabot Lowell. Francis Cabot Lowell died in 1817, at the early age of forty-two, but his work did not die with him. Capitalized at $400,000, the Waltham mill dwarfed its competition. So great were the profits at Waltham that the Boston Associates (the group of Boston investors that joined with Lowell) soon looked for new sites, first at East Chelmsford (renamed Lowell), and then Chicopee, Manchester, and Lawrence.
