The Peekskill Museum was formerly known as The Herrick House. Dwight Stiles Herrick, was born in 1845 in Chicopee Falls, Massachusetts from a distinguished New England family. After moving to Peekskill, Herrick taught classes at the Peekskill Military Academy from 1867 to 1870. Herrick then studied law with Edward Wells, a founder of P.M.A. Dwight became a lawyer in 1870, and later a Trustee at the Academy. Herrick’s office was located at 936 South Street with his partner Stephen Lent, located on the second floor of the then Griffen and Lent Drug Store. The building is now occupied by Arthur Weeks and Son Jewelers
Dwight married Sarah Frances Simpson in 1871. She had been born in New York City, the daughter of wealthy businessman John Simpson. Mr. Simpson was at one time the owner of the Eagle Hotel on Main Street and built what is now called the Colonial Terrace (a large Victorian mansion now used as a catering establishment) on Oregon Road, just North of Peekskill. John Simpson died in the Herrick House in 1881. His estate was then valued at between $300,000 to $500,000. The Herrick’s received interest from a $50,000 trust fund from his will.
Mr. and Mrs. Herrick were organizers and members of the local Handel and Hayden Music Society.
