He won the 2007 [[Nobel Prize in Physics]] for discovering [[giant magnetoresistance]]. This made [[gigabyte]] [[hard disk drive]]s easier to make. Half of the prize was given to [[Albert Fert]]. Fert discovered giant magnetoresistance at the same time. But, Fert and Grünberg did not work together.<ref>{{cite web | url=http://nobelprize.org/nobel_prizes/physics/laureates/2007/index.html| title=The Nobel Prize in Physics 2007 | accessdate=2007-10-09 |publisher=The Nobel Foundation}}</ref> ==Early life== Grünberg was born in [[Pilsen]], [[Bohemia]].
