Dear Warren:

First let me say that I am glad to have a chance to speak on the Philharmonic program, and I thank you for inviting me.

I enclose the first draft of my talk. It is 1,650 words -I thought that it would be better to get the advice of your group before pruning it. I shall be glad to have advice. It would be possible, of course, to give scores of examples of structures, but I have strived to get a message across - and I hope to be allowed to.

As for item 11. of your suggestions: Perhaps the most interesting feature of my scientific career is its breadth - possibly no one (modern) has covered - or ranged over - more branches of science.

Theoretical (even mathematical) physics: Book on quantum mechanics; papers on momentum eigenfunctions (Gegenbauer functions), spinning electron, etc.

General physics: X-ray spectra, magnetism, line spectra (book).

General and inorganic chemistry: Text book, many papers.

Applied chemistry: B.S. in Chemical Engineering; research on propellants; member of Explosives Division of NDRC.

Organic chemistry: Theory of resonance, etc.

Structural chemistry: Theory of directed covalent bonds, many crystal structure and electron diffraction studies, etc. Book: "Nature of the Chemical Bond".

Physical chemistry: Entropy of supercooled liquids, entropy of ice, properties of electrolytes, etc.

Analytical chemistry: instrument for analyzing for oxygen.

Mineralogy: Structure of silicate minerals and sulfide minerals.

Biochemistry and biology: Work on hemoglobin and other proteins.

Medicine: Work in immunochemistry; oxypolygelatin as a plasma substitute; Consultant CMR; Member Medical Advisory Committee to V. Bush.

Sincerely yours,

Linus Pauling
