Cogswell Heritage House

The American School for the Deaf (ASD) founders were well aware of the groundbreaking importance of their new endeavor, and they and their successors saved a great many letters, teaching aids, illustrations, books, and other objects. These items remained in the school’s possession and now form a rich collection that has become a credible base for research among graduates, historians, genealogists, authors, editors, and scholars.

This carefully organized collection includes the histories of deaf education, religion, Hartford, and the United States. It also links ASD’s heritage and regional impact with its contributions to the Deaf Community as a whole.

The school’s first museum was organized in the Historical Room of the Gallaudet Building in 1967, and expanded in 1977. When renovations to the Gallaudet Building were planned in 2008, the archives were relocated to the former

Principal’s House on campus.

Collaboration with other historical societies, research, and new discoveries have also broadened the school’s collection. Additions to the archives over the years have been most welcome, but it has become a challenge to showcase objects in the museum’s current location without physical barriers. Understanding the importance of spatial elements, ASD is currently exploring on-site options to, once again, expand its museum with an eye towards improved design, layout, access, circulation routes, and



ASD knows that the best way to meet the challenge of engaging visitors and teaching its history is through careful planning. Along with added space, look for upgrades that will include better graphic panels and object labels, additional displays of photos/map /drawings/art (currently in storage), handout leaflets, seating, model objects, and expanded library, research, and storage facilities.

Also planned are interactive exhibits, events, audio (narratives, music, etc.), video (ASL interpretations, archival film, interviews), and activity stations.


The ASD community is proud of its historic collection and will continue to preserve its past and cultivate its future. All those who share this interest are encouraged to consider a gift to American School for The Deaf Archive Fund, or recommend the names of others who may have an interest, or assist in building the archive collection.
