The Wissahickon Valley is named for the creek that runs through central Montgomery County and into the City of Philadelphia, where it empties into the Schuylkill River. The Wissahickon Valley Historical Society documents the history of that portion of the valley that encompasses the Borough of Ambler and Townships of Whitpain and Lower Gwynedd. The Borough of Ambler was originally known as the Village of Wissahickon. From 1881 and for nearly a century, the borough's most prominent business was the Keasbey and Mattison Company, asbestos manufacturers. The palatial estate of company founder Dr. Richard V. Mattison, "Lindenwold," has been occupied by St. Mary's Villa for Children since 1936. Ambler was also the home of the Pennsylvania School of Horticulture for Women, one of the first schools in the nation to educate women for careers in horticulture and agriculture. The nearby townships of Whitpain and Lower Gwynedd are among the oldest in Montgomery County. Both settled by Quakers in the 17th century, Whitpain Township was established in 1701 and Lower Gwynedd Township in 1891 when it broke off from Upper Gwynedd.
