Two Nobel laureates in conversation: Robert Robinson listens to Dorothy Hodgkin's account of her life scientific

In 1974 the Nobel laureate Sir Robert Robinson OM PRS (1886–1975) was gathering information for the memoirs he was writing. As part of his research, he recorded a conversation with his former student, fellow Nobel laureate Professor Dorothy Hodgkin OM FRS (1910–1994), during which she outlined the key stages of her career. She explained the principles underlying crystallography and described her work on the structure of biological molecules including penicillin and vitamin B12—for which she received the Nobel Prize—and on insulin. This paper includes a verbatim transcript of the conversation, which reveals the key figures in Hodgkin's career and the technical breakthroughs which underlay the elucidation of the structure of very large complex molecules. The paper includes a commentary on the value of oral accounts and concludes on the issues raised and not raised during the conversation. Sir Robert was President of the Royal Society between 1945 and 1950 when women were first elected Fellows. Hodgkin was elected in 1947. However, no mention is made of the challenges facing women developing a scientific career in the first half of the twentieth century
