## About

Founded in 1909, the Houston Museum of Natural Science operates as a civic institution with an endowment rather than a single-family pool. President and CEO Joel A. Bartsch leads the organization, while board chairman Randa Duncan Williams, also chairman of Enterprise Products Partners, provides governance ties to Houston's industrial wealth. The endowment's corpus was built through a century of earned revenue and major donor gifts, including $5 million from the Cullen Foundation for the Cullen Hall of Gems and Minerals and $2.3 million from the Dan L Duncan Foundation for education and preservation. The endowment's investment posture mixes direct fund commitments with a mandate that spans buyout, venture, growth, secondaries, and fund-of-funds. The board draws on Houston's energy and civic leadership, with the late S. Reed Morian, former CEO of DPC, serving as vice chairman until his passing in 2024. Adjacent philanthropic vehicles are integrated directly into the museum's operating structure — the Morian Hall of Paleontology, Cullen Hall of Gems and Minerals, and John P. McGovern Hall of the Americas function as named collection pavilions whose endowments sit within the broader institutional portfolio. The museum's professional network includes membership in the American Alliance of Museums and the Houston Museum District Association. The institution's structural profile differs markedly from private foundations and family offices: it is a public-facing educational charity whose endowment exists primarily to preserve and exhibit a collection of scientific assets — including a triceratops, a T-Rex, and the Guido T. Poppe malacology collection — rather than to maximize financial return for external beneficiaries. This creates a perpetuity-oriented, rather than fundraising-cycle-oriented, investment horizon.

Named donors include the Cullen Foundation, which contributed $5 million for the gem hall, and the Dan L Duncan Foundation, which provided $2.3 million for education and preservation, according to Altss research.

### How is the Houston Museum of Natural Science related to the Cullen Foundation or Duncan family?
