Sidney Felsen founded Gemini Gel (Graphics Editions Limited) in 1966 and soon after began to photograph the artists who came to work in what has become America's premier graphics studio. Artists from Bruce Nauman and architect Frank Gehry (who also designed the Gemini Studios in 1979) to the American masters Robert Rauschenberg, Jasper Johns, and Roy Lichtenstein became subjects for Sid Felsen's camera. In 2001 the National Gallery in Washington opened an exhibition celebrating the prints of Gemini GEL and Sidney Felsen's portraits of the artists at work.
