"The meetings at Stanford...were very interesting. There were lots of times when people wanted to know what Pauling would say about different things, so [John] Edsall and I had to speak for you, taking of course, a fair amount of the credit."

Charles Coryell. Letter to Linus Pauling. July 4, 1941.

"Dr. Charles Coryell, who has worked on the metallurgy project at the University of Chicago for a couple of years, received his training here, and then became Assistant Professor at the University of California at Los Angeles, is an extremely able young inorganic and physical chemist, with a great amount of energy. I recommend him most highly."

Linus Pauling. Letter to George T. Felbeck. November 17, 1943.

"Life is too complicated to permit a complete understanding through the study of whole organisms. Only by simplifying a biological problem -- breaking it down into a multitude of individual problems -- can you get the answers. In 1935, for example, Charles Coryell and I made our discovery about how oxygen molecules are attached to the iron atoms of hemoglobin, not by getting a cow and putting it into our magnetic apparatus, but by getting some blood from the cow and studying this blood."
