MM 404...........20th century inventions...

....penicillin was discovered, so maybe not an invention, in 1928 by Alexander Fleming (but we all knew that didn't we). Since losing my spleen last year I now take this version of penicillin every day......... 


Penicillin was discovered in 1928 by Scottish scientist Alexander Fleming as a crude extract of P. rubens.[4] Fleming's student Cecil George Paine was the first to successfully use penicillin to treat eye infection (ophthalmia neonatorum) in 1930. The purified compound (penicillin F) was isolated in 1940 by a research team led by Howard Florey and Ernst Boris Chain at the University of Oxford. Fleming first used the purified penicillin to treat streptococcal meningitis in 1942.[5] For the discovery, Fleming shared the 1945 Nobel Prize in Physiology or Medicine with Florey and Chain.
