GalleristNY reports on the death of Ivan Karp:

Mr. Karp worked at Castelli from 1959 through 1969, during a hugely influential period that saw the gallery launch the career of Andy Warhol, Roy Lichtenstein, RobertRauschenberg, Claes Oldenburg, Tom Wesselmann and John Chamberlain. Before joining Castelli he had worked for the Martha Jackson Gallery.

Over its 43 years on West Broadway (first at 383, then 485), O. K. Harris has been known for its staunch support of representational (particularly Photo Realist) painting. It also presented early shows of a wide variety of artists, including Bill Bollinger. One of the largest spaces in Soho, it sometimes hosted up to five one-person shows at a time.
