Ambler is a borough in Montgomery County, Pennsylvania, in the United States. It is located approximately 16 miles north of the city center of Philadelphia, Pennsylvania. The historical territory of the Lenni Lenape was in the Delaware River Valley, in an area reaching from Cape Henlopen, Delaware, northward towards the lower Hudson Valley in southern New York. The area towards the south, including what is now Philadelphia and nearby Ambler, was the home of a linguistic group called the Unami.
Dawesfield was added to the National Register of Historic Places in 1991. During the American Revolutionary War, “Dawesfield” was the property of James Morris, and was used by General George Washington as a headquarters from October 21 to November 20, 1777. James Morris also owned one of the mills in the Ambler area. The Keasbey-Mattison houses are of interest in part because of the class differences revealed in the construction of different types of houses for workers, supervisors, and administrators, (not to mention Lindenwold Castle, home of Mattison himself.)
The Borough of Ambler is served by the Wissahickon School District. In 2004, the Wissahickon School District had 4,535 students. Wissahickon School District has six schools: four elementary, one middle (grades 6-8) and one high school (grades 9-12). Temple University, whose main campus is in nearby urban Philadelphia, has a suburban campus that is referred to as the Ambler Campus.
