Born Ogawa on 23 January 1907, Hideki Yukawa built his career on a single audacious idea: that nuclear forces required a new particle to make sense. Working purely from theory, he described mesons before anyone had observed one - a leap that redefined how physicists understood the forces binding protons and neutrons. When experiment caught up with imagination, the Nobel followed in 1949. He died on 8 September 1981, having opened a door that others would walk through for decades.
