Peter Higgs, Robert Brout and François Englert were jointly awarded the 2004 Wolf Prize in Physics for their work on the Higgs boson, which is a subatomic particle that is believed to be responsible for giving mass to all other subatomic particles. Higgs and Englert proposed the existence of the Higgs boson in the 1960s, while Brout developed Theory further in the 1970s.
