Alexander Fleming

Meddyg, biolegydd a dyfeisiwr oedd Syr Alexander Fleming, FRSE, FRS, FRCS(Peirianeg) (6 Awst, 1881 - 11 Mawrth, 1955). Ysgrifennodd lawer am chemotherapi, System imiwneddimiwnedd a bacteria.

Ei ddarganfyddiadau pwysicaf yw ensymau a lysosymau yn 1923 a'r sylwedd gwrthfiotig adnabyddus hwnnw: penicilin o'r llwydni Penicillium notatum yn 1928. Rhannodd Wobr Nobel gyda Howard Florey a Ernst Boris Chain[1] yn 1945.

Yn 1999, rhestrodd y cylchgrawn Time Fleming fel un o'r 100 person pwysicaf yn yr 20fed ganrif gan ddweud:

It was a discovery that would change the course of history. The active ingredient in that mould, which Fleming named penicillin, turned out to be an infection-fighting agent of enormous potency. When it was finally recognized for what it was, the most efficacious life-saving drug in the world, penicillin would alter forever the treatment of bacterial infections. By the middle of the century, Fleming's discovery had spawned a huge pharmaceutical industry, churning out synthetic penicillins that would conquer some of mankind's most ancient scourges, including syphilis, gangrene and tuberculosis.[2]
