6 Molecular modeling with kindergarten supplies Linus Pauling won the Nobel Prize in Chemistry in 1954 "for his research into the nature of the chemical bond and its application to the elucidation of the structure of complex substances". Pauling summarized his work on the chemical bond in The Nature of the Chemical Bond, one of the most influential chemistry books ever published. See:

7 “As a result of Kendrew's and Perutz' contributions it is thus becoming possible to see the principles behind the construction of globular proteins. The goal has been reached after twenty-five years' labour, and initially with only modest results” -- Professor Hagg The 1962 Nobel Prize in Chemistry Goes to… Max Perutz and John Kendrew "for their studies of the structures of globular proteins”.

8 The 1962 Nobel Prize in Physiology or Medicine… The Nobel Prize in Physiology or Medicine 1962 was awarded jointly to Francis Harry Compton Crick, James Dewey Watson and Maurice Hugh Frederick Wilkins "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material".

9 Experimental Methods for Structure Determination “Protein Structure and Function”, Petsko GA and Ringe D X-ray crystallography Nuclear magnetic resonance (NMR) Protein purification
