Letter from H. Fraenkel-Conrat to Rosalind Franklin
Heinz Fraenkel-Conrat was one of many virus researchers that Franklin visited during her 1954 trip to the United States. Like
many others, he was able to send her samples of the materials he was using. The TMV with heavy atoms, such as mercury, added
would help Franklin calculate the structure of TMV more accurately.

At last I have managed to package a sample of an iodo-TMV preparation for you, before it got used up for any other purposes.
To reward your patience, I am also sending you a very new derivative, containing methylmercuric residues attached to the -SH
groups. This preparation has not yet been described. [Rho]-Chloromercuribenzoate does not react with the virus.
I hope these preps will arrive safely and not dehydrated, and that they will prove of interest to you.
