11. Science. 1923-1994.
This section has been divided into fifteen thematic sub-sections, which, when taken
as a whole, reflect the extraordinary breadth of Linus Pauling's scientific biography.
Boxes in the Science section typically hold manuscripts, research notes, correspondence,
figures, experimental data, non-Pauling reprints and other scientific research materials.
Generally speaking, materials have been arranged and cataloged according to research
topic. However, two sub-sections reflect the institutional architecture either supporting
or directing Pauling's work during specific periods of his life. For example, the
bulk of the collection's holdings concerning Pauling's relationship with the American
Chemical Society have been cataloged under the rubric "Scientific, Research and Grant-Funding
Institutions." A similar approach has been taken with much of Pauling's work sponsored
by the Guggenheim Foundation, Rockefeller Foundation, Ford Foundation, etc.
