Hodgkin was invited to a conference on steroid hormones at the Medical Foundation of Buffalo Research Laboratories to celebrate the publication of the Atlas of Steroid Structure, dedicated to her, J.D. Bernal and I. Fankuchen. She gave the keynote address, probably on the early history of steroid structure. She then visited the University of Connecticut, where she gave an informal talk. Following this Hodgkin went to Harvard University to give the John T. Edsall Lecture on 'The Structure of Insulin in Crystals'.
