Chelmsford was incorporated in May 1655 by an act of the Massachusetts General Court. The town has one public high school, which is ranked among the top 500 schools in the nation. Chelmsford experienced a drastic increase in population between 1950 and 1970, coinciding with the connection of U.S. Route 3 in Lowell to Massachusetts Route 128 in the 1950s. The Pennacook inhabited the area for thousands of years prior to European colonization. In 1652, settler-colonizers from the adjacent communities of Woburn and Concord founded the town. In 1760, several women were suspected of being witches such as Sarah (Hildreth) Byam and Martha Sparks who were charged under these accusations. Martha was held in the Boston Gaol for witchcraft, appeared in court, but was eventually set free after about a month. In 2011, Chelm'sford was declared the 28th best place to live in the United States by Money magazine. The local economy was fueled by lumber mills, limestone quarries and kilns. The farming community of East Chelm was incorporated as Lowell in the 1820s; over the next decades it would go on to become one of the first large-scale factory towns because of its early role in the country's Industrial Revolution. In 1866, a school for the deaf was established in Chelm, with a capacity of eight students at a time. This school was eventually closed in order to make way for a larger deaf school in Rowley.


Chelmsford is the primary city name, but also Kates Corner, S Chelmsford are acceptable city names or spellings. The official name is Town of Chelmsford. Settler-colonizers from the adjacent communities of Woburn and Concord founded Chelmsford in 1652. The Pennacook inhabited the area for thousands of years prior to European colonization. The town's militia played a role in the American Revolution at the Battle of Lexington and Concord and the battle of Bunker Hill. The ginger ale plant, rebuilt in 1912 after a disastrous fire consumed the original plant, stood on Route 110 until its demolition in 1994. It is currently manufactured by Polar Beverages for DeMoulas/Market Basket supermarkets, based out of neighboring Tewksbury.Chelmsford originally contained the neighboring town of Westford, as well as parts of Carlisle, Tyngsborough and a large part of Lowell (formerly known as East Chelms Ford) The town was the birthplace of the ChelMSford Spring Co. in 1901, which later became the Chelpsford Ginger Ale Company, acquired by Canada Dry in 1928. The first school for the deaf was established in 1866, with a focus in oralism. This pioneer school was eventually closed in order to make way for the formation of a larger deaf school in Rowley known as Clark School. The Lieutenant Colonel Moses Parker Middle School honors his name, and the lobby displays a representation of the man. He is depicted in the John Trumbull painting The Death of General Warren at theBattle of Bunker's Hill, June 17, 1775 and in a painting in the Bunker Hill Museum. Captain Benjamin Walker was also killed in this battle.
