# bio (long form, separated for readability)
bio: |
  Johannes Hevelius was born in Gdańsk on 28 January 1611, when the city sat inside the Polish–Lithuanian Commonwealth. He rose to councillor and eventually chairman of the Old Town's council, managing civic affairs in one of Europe's busiest ports. Astronomy consumed his other hours. His lunar charts set the standard for rendering the moon's surface, work so precise it earned him that "founder" title. He also identified ten new constellations; seven remain in the sky charts astronomers use today. He died on his 76th birthday, 28 January 1687.
