Keasbey and Mattison Company was a manufacturing company that produced asbestos-related building products, including insulation and shingles. Founded in 1873 by Henry Griffith Keasbey (1850-1932) and Richard Van Zeelust Mattison (1851-1935), the company moved to Ambler, Pennsylvania, in 1881. By World War I, the Keasbey and Mattison Company's presence caused Ambler to be known as the "asbestos capital of the world".[1] Keasbey and Mattison was purchased by Turner & Newall in 1934.
