In 1966, at the age of forty-one, Sidney Felsen moved from the world of accounting to that of art, founding the artists’ workshop and fine-art print publisher Gemini GEL in Los Angeles. With Gemini GEL, Sidney quickly got to work with some of the biggest artists of the twentieth century: Man Ray, Josef Albers, Jasper Johns, and Robert Rauschenberg, to name a few. And Gemini GEL continues its work with new generations of artists, including Julie Mehretu, Tacita Dean, and David Hammons.

Sidney Felsen is the co-founder of Gemini G.E.L., a printmaking studio in Los Angeles that has been operating since 1965. Some of his photographs documenting the artists at work at Gemini are collected in the book The Artist Observed.
