After Princeton, Peter earned master’s degrees from the Yale School of Forestry and the Teachers College at Columbia. Early in his career, he taught at the Chapin School, the Masters School, and Hardwood Island. Peter was passionate about nature and conservation, involving himself in causes from the coast of Maine to New Jersey and the Caribbean.
He served on many boards involving his passions, including the Frick Collection, the Helen Clay Frick Foundation, and Greenwood Gardens, the New Jersey estate where he grew up, which he transformed into a magnificent public garden. He was also a council member of the Maine Coast Heritage Trust. Peter was an elegant writer, a prolific reader, a lover of poetry, and a talented landscape painter. He married late in life and took great joy in his life with Sofia and Theo, and will also be sorely missed by his corgi Ginnie. Donations in his memory can be made to Greenwood Gardens or The Frick Collection. A memorial service will be held at a later time.
