The General Harry C. Trexler Collection Finding Aid provides an overview of our collection of materials related to General Harry C. Trexler (April 17, 1854-November 17, 1933).  Born in Easton, Pennsylvania, he was an American industrialist, conservationist, and major philanthropist.  In 1885, Trexler married Mary M. Mosser.  They were married for 48 years, until his death in 1933 from injuries suffered in an automobile accident.  Mary died one year later.  They had no children.  Through a charitable trust Trexler established in his Will, his wealth continues to provide a major benefit to the people and community of Lehigh County, Pennsylvania. 

Our collection of Trexler materials described in the Finding Aid includes ledgers, land records, maps, scrapbooks, photographs, and ephemera related to Trexler’s life and the legacy he left behind.  Our Finding Aid is designed to guide “in-house” research.  This collection is not digitized for off-site viewing or research.  Questions should be directed to Jill Youngken, Director of the archives at 610-435-1074 or 

Thank you for your interest in the life of General Harry C. Trexler.
