This is perhaps the largest contributor to the legacy of MC Escher, as his works such as Ascending and Descending and Waterfall are widely recognized as some of his best works. As I discuss in my research paper(see page titled Papers) he is far from the only contributor to impossible objects, but it is a safe assumption that without the recognition he received for these works perhaps impossible objects would not have the applications and renown they do in the art and psychology disciplines.
