## About

John D. Rockefeller Jr. founded Sleepy Hollow Restorations in 1951, which later became Historic Hudson Valley. The organization preserves and operates a portfolio of National Historic Landmarks, including the Rockefeller estate Kykuit, Philipsburg Manor, Washington Irving’s Sunnyside, and Van Cortlandt Manor. Its endowment sustains these properties and funds educational programming for over 300,000 annual visitors. Historic Hudson Valley deploys its endowment across a broad, multi-asset-class strategy that includes venture capital, buyout funds, distressed debt, and growth equity, spanning seed-stage to secondary transactions. The portfolio supports a physical footprint of historic sites and curated collections — among them the Matisse and Chagall stained glass windows at Union Church of Pocantico Hills and a library-manuscript collection — effectively operating a museum-quality asset base while drawing revenue from public tours and school programs. The institution runs its operations from a headquarters building at 639 Bedford Road and partners with the National Trust for Historic Preservation and the Rockefeller Brothers Fund to manage the public tour program at Kykuit. Governing the organization is a board of trustees chaired by Mark F. Rockefeller, with President Waddell Stillman overseeing day-to-day operations and investment decisions. The endowment is supported by donor societies, including the Pocantico Society, which provides backers with exclusive access to private estates and collections. Structurally, Historic Hudson Valley functions as an asset-owning operating foundation rather than a pure grantmaker — its capital supports owned real estate and programming rather than third-party grants. The combination of a directly managed historic-site portfolio and a diversified financial endowment creates an unusual hybrid: a cultural institution that is simultaneously a long-duration real asset owner and an active, multi-strategy allocator.

## Questions

### Who runs investment decisions at Historic Hudson Valley?

Investment decisions are overseen by the president and the board of trustees. Waddell W. Stillman serves as president of the institution, and Mark F. Rockefeller chairs the executive committee of the board. The governing structure brings together operational leadership and a direct family link to the founding Rockefeller legacy.

### Is the endowment managed internally or outsourced?

Historic Hudson Valley has not publicly disclosed whether its endowment is managed internally or through external managers. The board and executive leadership govern the allocation, but the precise operational setup of the investment office is not detailed in public sources.

### How is Historic Hudson Valley related to the Rockefeller Brothers Fund?

The Rockefeller Brothers Fund is a business partner of Historic Hudson Valley. Together they operate the public tour program at Kykuit, the historic Rockefeller family estate that is owned by the National Trust for Historic Preservation and operated by the partnership.

### Does Historic Hudson Valley make grants or run its own programs?

It operates primarily as an operator of historic sites and educational programs rather than as a grantmaking foundation. Revenue from tours, events, and the endowment funds its own programming — school visits, public tours, and large-scale cultural events — rather than being distributed to third parties as grants.

### What real assets does Historic Hudson Valley own?

The organization does not own all the sites it operates — the National Trust for Historic Preservation owns Kykuit — but its asset base includes Philipsburg Manor, Washington Irving’s Sunnyside, Van Cortlandt Manor, the Union Church of Pocantico Hills, and its Pocantico Hills headquarters. The stewardship model combines owned real estate with operating partnerships.
