# bio (long form, separated for readability)
bio: |
  Born in Poland on 24 May 1686 to a German family, Fahrenheit spent most of his working life in the Dutch Republic as a physicist and instrument maker. His breakthrough was precision: he redesigned thermometers so thoroughly that independent observers, each holding their own Fahrenheit instrument, could finally compare readings and mean the same thing. He produced the first successful mercury-in-glass thermometers, sharper and more stable than the spirit-filled models that came before. The instruments caught on, and with them the temperature scale he'd marked on their tubes. He died 16 September 1736, leaving a unit of measure that outlasted him by centuries.
