If Florey and Chain were responsible for the groundbreaking development, why do we credit Fleming with the miracle of antibiotics? All three won the Nobel prize together, but it's rare to hear more than Fleming's name mentioned in conjunction with penicillin. Reports say
that Florey was too humble and did not want recognition for his work. In fact, he thought that perhaps his drug was too effective and created a larger problem
of population growth. Florey didn't enjoy talking to the publicists who wanted to report on his work; Fleming did. Fleming wasn't self-seeking or vain, but rather was unable to turn reporters away. The credit goes largely to Fleming because talked and Florey/Chain didn't.
