The Agassiz Society, a natural history study group, met in this room.

In the center of the photo one can see the large flannel-covered table used by the group, which revolved in order for microscopes to be passed between members.

The library's auditorium was the site of its dedicatory exercises on November 28, 1893.

The auditorium also held the library's grand piano, donated by Rachel Hampson, and was the site of many musical events in early Fairfield as well as lectures, meetings, poetry recitations, and performances of all varieties.
