Notable: The Connecticut Historical Society & Museum, One Elizabeth St., Hartford, is located in a Colonial Revival mansion originally owned by inventor Curtis Veeder, who moved to the city to start a company.

The Veeder Manufacturing Company produced counting and precision manufacturing devices, all invented and designed by Veeder. An exhibit in the original living room of the house (which Veeder had built in 1928) features wall labels, blow-ups of the original blueprints, and an interactive touchscreen explaining the history of the building and the Veeder family. Free admission, 9 a.m. until 5 p.m.
