He studied architecture at Georgia Tech from 1925 to 1927, and went on to get a Bachelor of Fine Arts at the University of Pennsylvania in 1929. From there he attended the University of South Carolina from 1932 to 1933, graduating with a degree in design and painting in the midst of the great depression. Career Geis served as a coauthor and illustrator of many biochemical books that were written by Albert Lehninger and Richard E. Dickerson, as well as the book How to Lie with Statistics by Darrell Huff. He was a frequent contributor to Scientific American.
