Editing Dorothy Hodgkin (section)

===Mentor===
Hodgkin's mentor [[Professor]] [[John Desmond Bernal]] greatly influenced her life: scientifically, politically, and personally. Bernal was a key scientific adviser to the UK government during the Second World War. He was also an open and vocal member of the [[Communist Party of Great Britain|Communist Party]] and a faithful supporter of the [[Soviet Union|Soviet]] regime until its [[1956 Hungarian Revolution|invasion of Hungary]] in 1956. He was a chemist who believed in equal opportunity for women. In his laboratory, Hodgkin extended work that he began on biological molecules including sterols. She helped him to make the first X-ray diffraction studies of pepsin and [[Crystallin|crystalline protein]]. Hodgkin always referred to him as "Sage". They were lovers before she met Thomas Hodgkin.<ref>{{cite book |last1=Brown |first1=Andrew |title=J.D.
