In his brief yet wide-ranging career, Theodore Robinson established himself as a major figure in the early years of American impressionism, one of the only artists to work alongside Claude Monet. New York dealer Ira Spanierman, who along with the Baltimore Museum of Art's Sona Johnston is co-authoring the catalogue raisonne of Robinson's work, calls Robinson "one of the few greats" in American impressionism, an assessment backed up by the impressive prices for the artist's work, with a record auction price in excess of two million dollars.
