“ Carpets and textile machinery are allied manufactures of importance. There are other factories for machinery, patent medicines, boots and shoes, perfumery and cosmetics, hosiery and rubber heels. Lowell was the home of the inventor of rubber heels, Humphrey O’Sullivan. ”

“ The Lowell textile school, opened in 1897, offers courses in cotton manufacturing, wool manufacturing, designing, chemistry and dyeing, and textile engineering; evening drawing schools and manual training in the public schools have contributed to the high degree of technical perfection in the factories. ”

“ Lowell ranked fifth in value in 1905 and fourth in 1900 among the cities of Massachusetts; more than three-tenths of the total population are factory wage-earners, and nearly 19% of the population are in the cotton mills. ”
