Museum executive director Greg Perry says the collection will be a boon to the institution's 20th-century holdings.
Grippe was a Cubist-inspired sculptor and printmaker who died in 2002. His widow made the museum donation.
Grippe's property, including a New York apartment and home and studio on Long Island, will be sold. Proceeds will be used for museum fund in honor of Peter and Florence Grippe.
