Who was the first guy who took penicillin?

Answer 1

Penicillin was first described by Alexander Fleming in 1929. He proposed to use it as a disinfectant, but didn't believe it would work in the human body.

A Cecil George Paine was the first to apply it externally to treat a disease called sycosis barbae, but was unsuccessful. As it was only externally applied here, so I'm not sure that qualifes as 'taking it'.

Howard Florey and Ernst Chain continued to do experiments with penicillin in mice, but didn't have enough to treat humans. In 1942 the first human experiment was conducted by Orvan Hess. So the his patient was probably the first to take it.

If you want to be clever about it you could say that penicillium, the genus of mould that produces penicillin, is a common food-spoiling mould. Therefore the first human to ever eat spoiled food would qualify for your answer.

Penicillium roqueforti, the mould in blue cheeses produces small amounts of penicillin, so perhaps the first person to take penicillin was a frenchman.
