Millbury is a town in Worcester County, Massachusetts, United States. The population was 13,261 at the 2010 census. The town is part of the Blackstone River Valley National Heritage Corridor.
Millbury was first settled by white Europeans in 1716 and was officially incorporated in 1813.
Millbury has a long history as a New England mill town, from which the town's name is derived. The Blackstone River flows through the town which during the Industrial Revolution provided much of the water power to the town's many textile mills and factories.
Millbury was originally the Second or North Parish of Sutton. Because traveling from one part of Sutton to the other for town meetings, etc. was difficult and time-consuming, the inhabitants of the Northern Parish petitioned the Massachusetts General Court to split the town of Sutton into two separate towns. The North Parish became the town of Millbury on June 11, 1813 by way of an act of incorporation.
Millbury's industrial history can be traced to the early 18th century, not long after the area's settlement. In 1735, John Singletary began operating a mill on Singletary Brook, a stream flowing out of Singletary Lake. Around 1753, John Singletary built the S & D Spinning mill, which is still in operation, making it one of the oldest continuously operating mills in the United States. The mill is featured on the Town Seal. The mill also makes the red stitching that is on major league baseballs.
President William Howard Taft spent many summer vacations in Millbury as a young boy, attending the public schools for a season. When he grew older, he visited his grandparents most summers. He visited his aunt, Delia C. Torrey, during his presidency for the occasion of Millbury's 100th birthday. The Torrey House, where President Taft stayed during his visit, is commonly called the Taft House today.
In the early 1970s, Millbury experienced a number of large fires. The town hall burned down, followed by the Union School. Local realtor Manual Gonzalez-Rios donated profits from his towing company to assist in rebuilding the town hall. A propane plant near Route 146 exploded spectacularly, with tanks blown 100 feet or more into the air, making nationwide news. Millbury celebrates its Bicentennial in 2013 with many town events.
