[Alfie Simpson]

Can someone give me a brief overview of QCD, I'd like to know famous physicists that worked in the field, the main theory's it includes, when did it begin and why do we study it? Thank you.

Hi Alf, good question ! No easy answer, I'm afraid.
Look around at http://www.particleadventure.org/ too; very nice ! And http://pdg.lbl.gov/fireworks/intro_eng.swf too.
Perhaps you wnat to read the CERN courier of Jan 28, 2013 . They mention the great physicists that started QCD.
And there is lots more colourful stuff
