About this Marker
Dag Hjalmar Agne Carl Hammarskjöld (July 29, 1905 – September 18, 1961) was a Swedish economist and diplomat, the second Secretary-General of the United Nations, who served from April 1953 until his death in a plane crash a little over eight years later. The plaque on Foggintown Road marks the country house, two miles north of Brewster village, that Hammarskjöld used as a weekend retreat throughout those eight years. He did not own the property: the house was rented to the United Nations from its owner, Mrs. Olga Freeman of Brewster, for Hammarskjöld’s use during his tenure as Secretary-General.
What the Southeast Museum Association chose to commemorate, in the plaque’s simple and striking phrase, is the seclusion. Not the diplomacy, not the Nobel Peace Prize, not the office — the privacy of a hard-driven public man at his small country house on a back road in Putnam County.
The dedication ceremony
The Southeast Museum Association dedicated the plaque on October 24, 1973 — United Nations Day, twelve years after Hammarskjöld’s death and twenty-eight years to the day after the UN Charter took force in 1945. The ceremony drew a notable list of speakers to a small back road in Putnam County: Mrs. Olga Freeman herself, the owner who had rented the house to the United Nations; Knut Hammarskjöld, the late Secretary-General’s nephew (then the Director General of the International Air Transport Association); H.E. Olof Rydbeck, the Permanent Representative of Sweden to the United Nations; and Brian Urquhart, then a UN Assistant Secretary-General and a longtime senior Hammarskjöld colleague. Several hundred members of the public and representatives of local civic organizations attended.
September 18, 1961
Hammarskjöld died on the night of September 17–18, 1961 when the DC-6 carrying him to ceasefire negotiations during the Congo Crisis crashed in dense bush near Ndola, in the British colony of Northern Rhodesia (today Zambia). All sixteen people on board were killed. He was 56 years old. In December he became the only person ever awarded the Nobel Peace Prize posthumously. The exact cause of the crash has been debated for more than sixty years. The United Nations has mandated a series of inquiries over the decades; the most recent, led by former Tanzanian Chief Justice Mohamed Chande Othman as the Secretary-General’s “Eminent Person,” reported in October 2024 that it remains plausible that an external attack or threat caused the crash. The General Assembly has repeatedly voted to continue the inquiry, and in September 2025 Secretary-General António Guterres asked Justice Othman to carry his work forward and renewed the call for member states to release any records they hold. No party has ever been formally held responsible, and the case remains officially open at the UN.
The house itself has a deep local history that predates Hammarskjöld by more than a century and a half — from Lot 8 of the Philipse Patent through the Gay family of Foggintown to its mid-twentieth-century ownership by Olga Freeman.
