Letter from Rosalind Franklin to Donald L. D. Caspar
Description:
Biophysicist Donald Caspar had recently finished his doctoral work on TMV structure, and had contacted Franklin at James Watson's suggestion. In this letter she expressed her interest in his results and discusses her own work briefly. Caspar worked with Franklin's team during the 1955-56 year, helping them determine the configuration of TMV.

8th November, 1954
Dear Dr. Caspar,
Thank you very much for your letter. I am very interested in your results.
I have calculated Fourier projections from the equatorial data, in very much the same way as you (using the theoretical shape of the central peak) and I find a heavy density shell at about r = 55A. My intensity measurements are undoubtedly less accurate than yours, but they extend to much larger angles, which enabled me to calculate a complete projection rather than its difference from a uniform rod.
I am at present busy writing up this and other aspects of the work and hope to be able to send you a copy of a draft paper in a week or two.
Yours sincerely,
Rosalind Franklin
