The Waterbury Button Museum is a permanent exhibit of approximately 10,000 buttons on display. The Button Museum was assembled by Warren F. Kaynor for the Waterbury Button Company more than 50 years ago. It includes buttons from all over the world, with many 18th and 19th century examples. The Button Museum was given to the Mattatuck Museum by the Waterbury Companies, successor to the Waterbury Button Company, which has been making buttons in Waterbury since 1812.
