The Met's collection of photographs, numbering more than 25,000 in total, is centered on five major collections plus additional acquisitions by the museum. Alfred Stieglitz, a famous photographer himself, donated the first major collection of photographs to the museum, which included a comprehensive survey of Photo-Secessionist works, a rich set of master prints by Edward Steichen, and an outstanding collection of Stieglitz's photographs from his own studio. The Met supplemented Stieglitz's gift with the 8,500-piece Gilman Paper Company Collection, the Rubel Collection, and the Ford Motor Company Collection, which respectively provided the collection with early French and American photography, early British photography, and post-WWI American and European photography. The museum also acquired Walker Evans's personal collection of photographs, a particular coup considering the high demand for his works. The department of photography was founded in 1992. Though the department gained a permanent gallery in 1997, not all of the department's holdings are on display at any given time, due to the sensitive materials represented in the photography collection. However, the Photographs department has produced some of the best-received temporary exhibits in the Met's recent past, including a Diane Arbus retrospective and an extensive show devoted to spirit photography. In 2007, the museum designated a gallery exclusively for the exhibition of photographs made after 1960.
