Maurits Cornelis Escher was a Dutch graphic artist, most recognized for spatial illusions, impossible buildings, repeating geometric patterns (tessellations), and his incredible techniques in woodcutting and lithography. Escher was born June 1898 and died March 1972. His work continues to fascinate both young and old across a broad spectrum of interests. Escher was a man studied and greatly appreciated by respected mathematicians, scientists and crystallographers yet he had no formal training in math or science. He was a humble man who considered himself neither an artist or mathematician. Intricate repeating patterns, mathematically complex structures, spatial perspectives all require a "second look". In Escher's work what you see the first time is most certainly not all there is to see.
