The Molecular Basis of Evolution
Dr. Christian Anfinsen published The Molecular Basis of Evolution in 1959. It was partly a basic primer on genetics and evolution for chemists, and partly a manifesto for the importance of chemistry to molecular biology, genetics, and evolutionary theory. The book was Anfinsen’s statement of belief and motivation, and through it he inspired many younger scientists.

Pharmacia Fine Chemicals Chromatography Column, c. 1975
Unknown donor, Accession 89.0001.321
This chromatography column from Pharmacia Fine Chemicals is one kind used in Anfinsen’s laboratory for affinity chromatography, a method that he began using in the 1960s to purify samples of the protein Staphylococcal nuclease, which enabled him to pinpoint the exact positions of the 149 individual amino acid units and their peptide bonds.
Other types of chromatography separate molecules based on size, differences in chemical or physical interactions, or strength of their ionic interactions. In affinity chromatography, a molecule called a “ligand” that binds to a specific receptor, is anchored to solid support. When a solution is passed over it, the ligand binds to the specific molecule that has an “affinity,” or natural bond, with it. After the other components of the solution are washed away, the now purified molecule is stripped from its support.
Key to Building 3 Directory Box, 1938
Donated by Steve Griffin, Accession 04.0008.002
Building 3 was one of the original laboratory buildings on the NIH’s Bethesda, Maryland campus, opening in 1938, to hold the Public Health Methods and Animal Unit. This key opened the Building 3 directory box, which listed the impressive array of scientists who worked in its laboratories, including five future Nobel laureates, three future NIH directors, a pharmaceutical company president, and 15 scientists who were inducted into the National Academy of Sciences

Staphylococcal Nuclease Model, c. 1965
Donated by Dr. Alan Schechter, Accession 89.0001.380
Staphylococcal nuclease was the focus of extensive experimental work under Dr. Christian Anfinsen from about 1963 to 1975. This molecular model was built as part of the educational program of Protein Chemistry evening seminars for Research Associates conducted throughout the 1960’s by Drs. Anfinsen and David Davies. It’s based on the x-ray crystallographic analysis done at the Massachusetts Institute of Technology under the direction of Professor Albert Cotton.
Employee Organization Chart
Donated by Dr. Rodney Levine, Accession 14.0044.001
This is a historical organization chart of the original Laboratory of Cellular Physiology and Metabolism that was started by Dr. Christian Anfinsen at what was then the National Heart Institute (now the National Heart, Lung, and Blood Institute, NHLBI), when he was recruited by NIH director Dr. James Shannon in 1950.
