The Grout Museum of History & Science was founded by Henry Whittemore Grout, a prominent Waterloo resident, financier and state legislator who loved to travel and collect reminders of the places he visited, sharing these finds with children in the community. By the time of his death, Grout had collected over 2,000 objects. His will established an endowment and named trustees to care for his collection, which was displayed for many years at the local YMCA.
