Andrew C. Colegrove, who operated an electrical appliance business in Mystic, was killed in a plane crash in California on August 24, 1951. The Colegrove Building at Mystic Seaport was built in 1952 as a memorial in his memory. Since 1962, the half of the building that faces the Mystic River has housed a printing exhibit, called the Mystic Press Printing Office. The original Mystic Press newspaper, started in 1873, had an office at West Main and Pearl Streets. The other half of the Colegrove Building contains a Ship Carver exhibit.
