The GREATER efficiency of Dawson's impure Manhattan penicillin

Biochemist Dr Karl Meyer's original idea in early September 1940, one approved by his three helping team mates, was to work towards the man-made synthesis of plentiful amounts of pure penicillin within about six months  ----and only then test it clinically on human patients.

Until then,the job of his microbiologist team mates Dr Henry Dawson and Dr Gladys Hobby, assisted by Meyer and his lab tech Eleanor Chaffee, was mostly to grow some penicillium mold and harvest the natural impure penicillin.
