The correspondence of Dorothy Hodgkin (1910-1994) introduced by her biographer, Georgina Ferry.

After the war, Dorothy juggled pioneering research with bringing up three children. Having cracked the structure of penicillin in 1945, she embarked on an even more complicated molecule, vitamin B12, while her husband Thomas spent long periods living and working in Africa. Elected as one of the first female fellows of The Royal Society aged just 36, Dorothy's reputation as a world class researcher was growing, rapidly.
