As mentioned by Jussi Mononen, four individuals did win two Nobel Prizes. Additionally, botanist Otto Warburg came close to doing so in 1944: some sources claim he was selected but prevented from receiving it by Hitler's regime; others claim he was nominated but not selected. There are a number of others who could or should have won two or more prizes: John von Neumann could easily have won prizes in both Physics and Economics (as well as the Turing Award and possibly even a Fields Medal). For a list of some of his many contributions, see his Wikipedia page.
