The Charles Egan Gallery opened at 63 East 57th Street (Manhattan) in about 1945, when Charles Egan was in his mid-30s. Egan's artists helped him fix up the gallery: "Isamu Noguchi did the lighting... Willem de Kooning and Franz Kline painted the walls."
A group show the next year included works by de Kooning, Joseph Stella, Josef Albers, Mark Rothko, Paul Klee and Georges Braque.
In 1948, Charles Egan Gallery held a solo exhibition of de Kooning's black and white paintings. Irving Sandler wrote that because of this exhibition, "de Kooning was established as a major Abstract Expressionist ... soon to be the most influential artist of his generation."
In 1949 Joseph Cornell had his first show at the Charles Egan Gallery.
