Re-setting the Allies' moral compass : the acid test of penicillin for wartime endocarditis

Please correct me : but in all my research I could find no indication that in his 15 years of medical research before October 16th 1940, (and he was a world-class expert in the area of strep bacteria) Henry Dawson had never written or spoken one peep - not one peep - on the subject of endocarditis, a very common and deadly disease, usually caused then by a variant of strep bacteria.
