History of the Ambler Boiler House

In 1881 the Keasbey & Mattison Company decided to move their manufacturing business from Philadelphia to Ambler, which was already a thriving farming and industrial community.  Entrepreneurs Henry G. Keasbey and Dr. Richard V. Mattison began constructing factory buildings and warehouse facilities such as the Ambler Boiler House, creating jobs that brought many new people to the Ambler area.

Recognizing the market potential of this discovery, the Keasbey & Mattison Company moved away from the manufacture of digestive aids and started manufacturing asbestos building materials and industrial supplies.

The business would continue to expand as asbestos roofing became more popular but the company would not survive the great depression.

impact on the local community as well as the long standing consequences of 
its industrial operations. The Keasbey & Mattison Company left an indelible 
imprint upon the Borough of Ambler in a legacy of unique buildings that lend this community its special character.
