More from Alexander Fleming
"I was just a dirty old man who left his dishes unwashed."
"I have been working for many years on the problem of finding substances which would destroy microbes in the body without injuring the cells of the body."
"It is a wonderful thing to be able to save lives with a simple substance."
"I am often asked if I foresaw the impact of penicillin. My honest answer is no."
"It is not difficult to make microbes resistant to penicillin in the laboratory by exposing them to concentrations not sufficient to kill them, and the same thing has occasionally happened in the body."
