Solomon R. Guggenheim, American art collector and philanthropist, founded the Solomon R. Guggenheim Museum (b. 1861)
Solomon Robert Guggenheim (February 2, 1861 – November 3, 1949) was an American businessman and art collector. He is best known for establishing the Solomon R. Guggenheim Foundation and the Solomon R. Guggenheim Museum in New York City.

Guggenheim was born into a wealthy mining family, and he founded the Yukon Gold Company in Alaska, among other business interests. He began collecting art in the 1890s, and he retired from his business after World War I to pursue art collecting. He eventually focused on modern art under the guidance of artist Baroness Hilla von Rebay, creating an important collection by the 1930s and opened his first museum in 1939.
