Did Merck consultant A N Richards diss penicillin during the first two years of the war?

Read any "Pollyanna" history of wartime penicillin and you quickly garner the impression that wartime Washington's top medical research bureaucrat, AN Richards of the famous OSRD organization, first learned of penicillin when his former student Howard Florey dropped by in the Fall of 1941.

In my opinion : "Bullfeathers" !
