Somerville

Somerville, city, Middlesex county, eastern Massachusetts, U.S. It lies along the Mystic River and is surrounded by Cambridge, Arlington, Medford, and the Boston neighbourhood of Charlestown. Settled in 1630, it was originally known as the Cow Commons and was entirely fenced in until 1685. In the city stands the Old Powder House (c. 1704), from which the British general Thomas Gage seized gunpowder in 1774. Somerville was the last of the Mystic valley towns to separate (1842) from the early Charlestown colony. Its name is said to honour Captain Richard Somers, hero of the Tripolitan-American War.

After the American Revolution, brickmaking became important, and the opening of the Middlesex Canal (1803), which passed through Somerville, added to its desirability as an industrial site. By 1835 the town was a regular stop on the new Boston and Lowell Railroad. Its most rapid growth in population and industrial activity occurred after 1900, when slaughtering and meatpacking developed as the principal economic activities. During World War II its population exceeded 100,000, owing to the demand for workers in the automobile and meatpacking industries.

The city is now a largely residential suburb of Boston with a service-based economy; light manufacturing is also important. Tufts University in Medford is a major employer. Inc. town, 1842; city, 1872. Pop. (2000) 77,478; (2010) 75,754.
