"Ronald Hare, a bacteriologist at Queen Charlotte’s Hospital in London, worked on GAS in the 1930s, a time when they regularly killed women who had just given birth and developed puerperal fever. He collaborated with Lancefield to prove that GAS was the killer. On 16 January 1936 he pricked himself with a sliver of glass contaminated with a GAS. After a day or two his survival was in doubt.
His boss, Leonard Colebrook, had started to evaluate Prontosil, a red dye made by I.G. Farben that prevented the death of mice infected with GAS. He gave it to Hare by IV infusion and by mouth. It turned him bright pink. He was visited in hospital by Alexander Fleming, a former colleague. Fleming said to Hare’s wife: ‘Hae ye said your prayers?’ But Hare made a full recovery."
