The house at 59 West Street in Seymour was built in 1940 as the home of Katharine Matthies, daughter of the Seymour industrialist, George Matthies. She was a philanthropist, who left as her legacy the Katharine Matthies Foundation, established following her death in 1987. Since 1995, the house has been the headquarters of the Seymour Historical Society.
