# bio (long form, separated for readability)
bio: |
  Willem Einthoven was born on 21 May 1860 in what is now Indonesia, trained as a medical doctor in the Netherlands, and turned his attention to physiology. In 1895 he invented the first practical electrocardiograph, a device that could record the heart's electrical activity with precision — transforming cardiology from educated guesswork into measurable science. The work earned him the Nobel Prize in Physiology or Medicine in 1924 "for the discovery of the mechanism of the electrocardiogram." He died on 29 September 1927, three years after the prize, having given doctors a way to see what had always been hidden.
