Vanderbilt Museum History

Vanderbilt Museum History

William K. Vanderbilt II, one of the richest men in the world, traveled the globe in the 1920s and ‘30s, collecting marine, invertebrate and bird specimens, and cultural artifacts for the museum he built on his Long Island estate in Centerport. Upon his death in 1944, he left his mansion, estate and museum to Suffolk County, New York, “for the use, education and enjoyment” of the public. The county opened the museum in 1950.

Educational opportunities at the Vanderbilt Museum and Planetarium.
