The Nobel Prize in Physics 1999

‘t Hooft and Veltman did their Nobel Prize work around 1970. Not until results were presented from the particle accelerator LEP at CERN, the European Laboratory in Geneva, was the breadth of their contributions realised.
     From these results, among other things, the mass of the top quark could be predicted. This prediction was confirmed when the top quark was discovered in 1995 at the Fermi Laboratory outside Chicago.
