Fritz Kahn (1888-1968), the pioneer of infographics, published more than 20 books with his artist friends and made thousands of scientific illustrations. His infographics attempt to take you inside the functioning of the human mind and body, by depicting people as rather whimsical contraptions. Here are his most amazing illustrations.

Kahn was chased out of Gemany by the Nazis, who burned his books, emigrated to Palestine, France and New York with the help of Albert Einstein. Along the way, he helped contribute to our understanding of ourselves.
