'Bravest, Maddest, Baddest Scientists'

The Guardian wants to know who you think the toughest scientists in the history of research are. Is it Australian doctor Barry Marshall? Marshall drank a Petri dish of Helicobacter pylori in order to prove that the microbes cause peptic ulcers, the Guardian says. Or maybe it was British physician Sir Henry Head? He operated on his own arm in 1908 to show how sensations are affected when peripheral nerves are cut. From the countess who trepanned her own skull with a dentist's drill to the guy who stuck his head into a particle accelerator and lived to tell about it, the Guardian wants to know who you think is the "hardest."
