The Whitin Machine Works (WMW) was founded by Paul Whitin and his sons in 1831 on the banks of the Mumford River in South Northbridge, Massachusetts. The village of South Northbridge became known as Whitinsville in 1835, in honor of its founder.The WMW became one of the largest textile machinery companies in the world. Known as The "Shop" to locals, would operate well into the 20th century, long after many of the New England mills had moved South.
