C. Arthur Knight was one of many virus researchers that Franklin visited during her 1954 trip to the United States. A colleague of Wendell Stanley, Robley Williams, and Heinz Fraenkel-Conrat, he sent her samples of cucumber virus, and in this letter also addressed questions about the differences between her x-ray diffraction values for TMV composition, and the biochemical findings by the Berkeley virus lab.
