His claim to fame was that Nat Finkelstein was the house photographer of the FACTORY. The complex which housed the studios of Andy Warhol.
(The Factory was Andy Warhol’s New York City studio, which had three different locations between 1962 and 1984. The original Factory was on the fifth floor at 231 East 47th Street, in Midtown Manhattan. The rent was one hundred dollars per year. Warhol left in 1967 when the building was scheduled to be torn down to make way for an apartment building. He then relocated his studio to the sixth floor of the Decker Building at 33 Union Square West near the corner of East 16th Street, where he was shot in 1968 by Valerie Solanas. The Factory was revamped and remained there until 1973. It moved to 860 Broadway at the north end of Union Square. Although this space was much larger, not much filmmaking took place there. In 1984 Warhol moved his remaining ventures, no longer including filming, to 22 East 33rd Street, a conventional office building)
In September 1962 Finkelstein was commissioned by Pageant magazine to do an article on the emerging Pop Art movement. The article was titled “What happens at a Happening?” it covered a Claes Oldenburg “happening” in Greenwich Village and was a break that would define his future. Two years later, while attending a party at the Factory, Finkelstein met Warhol, who had seen his photographs of Oldenburg’s “happening” in Pageant. Finkelstein offered his services as a photographer to the artist, and for the next three years he was a constant presence at the Factory. His iconic images of the include subjects such as the Velvet Underground performing live, Marcel Duchamp, Bob Dylan, Edie Sedgwick, Salvador Dalí, and Allen Ginsberg.
