# bio (long form, separated for readability)
bio: |
  Justus Freiherr von Liebig was born on 12 May 1803 in Germany and became a professor at the University of Giessen, where he invented the laboratory teaching method that still shapes how chemistry is taught. He's considered a principal founder of organic chemistry, but his sharpest legacy came from agriculture: he identified nitrogen and minerals as essential plant nutrients and popularized the law of the minimum — the idea that growth is choked by the scarcest resource, not the sum of available ones. That framework earned him the title "father of the fertilizer industry." He also developed a process for manufacturing beef extracts; with his blessing, the Liebig Extract of Meat Company launched to sell it, later introducing the Oxo bouillon cube. He died on 18 April 1873, having left chemistry both more rigorous and more useful.
