"Proof of the therapeutic action in vivo of penicillin against streptococcal and other bacterial infections. Building upon Fleming's work, the consequences of which had originally been widely unappreciated, even by Fleming himself, Chain and his co-workers concentrated penicillin and showed that it was probably the most effective chemotherapeutic drug known, and that it was relatively non-toxic. This led to mass production of the drug, which has saved untold millions of lives . . . Chain and Florey shared the Nobel Prize with Fleming in 1945"--Garrison-Morton 1934.
