Aristodimos Kaldis (August 15, 1899 in Dikeli, Ottoman Empire – May, 1979) was an artist and left-wing activist in New York.
During the 1940s he supported himself by giving lectures on art and archeology in a room at Carnegie Hall - with Willem de Kooning at the slide projector.
Also during the 1930s he participated with Communist League of America in organizing the 1934 New York Hotel Strike with B. J.
When the union leadership under the latter accepted concessions that were not acceptable to the CLA leadership they were expelled and joined Gitlow's sect, the Workers Communist League, to form a new group called the League for a Revolutionary Workers Party.
[1] Kaldis was also a painter, and since 1979, there have been numerous exhibitions of his work, including one in 1985 at the Artists' Choice Museum, which had the unique distinction of misnaming Phillip Pavia as Franz Kline in a picture of Kaldis and Pavia.
