Lowell pattern, also known as Lowell system or factory system, was a revolutionary manufacturing model developed in Lowell, Massachusetts during the early 19th century. The system was characterized by a highly centralized and organized production process, which relied on a large number of workers operating in carefully synchronized shifts to manufacture goods at a rapid pace. Synonyms for the Lowell pattern include the American system, the mill system, and the Waltham-Lowell system, which refer to the various adaptations and versions of the Lowell model implemented in other regions of the United States. The Lowell pattern is widely recognized as a significant milestone in the history of industrialization and revolutionized the way goods were produced and distributed across the country.
