Maurits Cornelis Escher (1898-1972). Escher initially pursued a career in architecture, but his passion for graphic arts soon changed his mind. He was taught the principles of graphic art by S. Jessurun de Mesquit in the Dutch town of Haarlem. After 1936, his realistic style and subject matter changed profoundly, when he drew the first of his famous ‘impossible realities’. During the rest of his life, Escher devoted himself to graphic art and the incorporation of transcendental ideas, such as metamorphosis and infinity, within the world of mathematics.
