# bio (long form, separated for readability)
bio: |
  Peter Andreas Grünberg was born 18 May 1939 in Germany and trained as a physicist. Working alongside Albert Fert, he discovered giant magnetoresistance — a quantum effect where tiny changes in magnetic alignment produce dramatic shifts in electrical resistance. The finding unlocked a revolution in data storage, enabling the gigabyte hard disk drives that would power the digital age. The work earned him the Nobel Prize in Physics. Grünberg died 7 April 2018.
