The gallery in its early days became known for hosting the first significant solo exhibitions of now leading art world figures including Alex Katz and Eva Hesse. Knox Martin had four solo shows at the gallery in the mid-1960s.The Fischbach Gallery would later move to two consecutive locations on 57th Street. In the 1970s Marilyn Fischbach hired Aladar Marberger as gallery director. Marberger shifted the gallery's emphasis from Avant-Garde Art to Realism. The gallery included artists Jane Freilicher, Ian Hornak and Neil Welliver.
In the early 1980s, Marilyn Fischbach decided to take on three additional investors in the gallery, although she remained a partial owner until her death in 2003. One of the investors, Beverly Zagor, became an active partner until her death in May 2011. Another investor and active partner, Lawrence L. DiCarlo, is gallery director.
The Fischbach Gallery remains open and has relocated to 210 Eleventh Avenue in New York. They focus primarily on contemporary realism.
