Dear Henry:
Thanks for sending me the clipping from the New York Times on the synthesis of some coenzymes by Todd.
Todd's work is of the greatest importance. I think that his earlier work on the synthesis of nucleosides and nucleotides
is probably to be considered as more important than just the synthesis of these coenzymes. This recent synthesis is a continuation
of the earlier work - an application of now synthetic methods that Todd discovered.
You no doubt remember that we had Todd over here, in the spring of 1938, and that we offered him a professorship. He would
have accepted it, I think, except that the British got busy and arranged for a professorship at Manchester to be given to
him. I believe that Todd is to be considered the leading organic chemist in Great Britain now, except for Sir Robert Robinson.
I talked with Todd about his work a good bit this summer; we stayed with the Todds in Cambridge. In particular, I discussed
the significance of his results with respect to the structure of nucleic acids. Principally as a result of this meeting
with him, I have now discovered, I believe, the structure of the nucleic acids themselves. Biologists probably consider
that the problem of the structure of nucleic acid is fully as important as the structure of proteins. I think that Dr. Corey
and I will probably send in a note on the discovery of the structure of nucleic acids next month; we want to check up on our
present structure a bit more before announcing it.
Sincerely yours,
Linus Pauling: W
