*"Moldy" Mary Hunt, a low-level lab worker, used a rotten cantaloupe to facilitate the first ''mass'' production of [[penicillin]].<ref>"Then, in 1943, Mary Hunt, a lab worker in Peoria, Illinois brought in a cantaloupe melon. It was said to have been infected with a 'pretty, golden mould'. This mould was 'Penicillium chrysogeum'. It yielded about 200 times as much penicillin as Fleming's mould. Florey used x-rays to mutate the mould, which eventually gave 1000 times the yield of penicillin from the original."
