Johann Dzierzon, or Jan Dzierzon ['jan 'd???r??n] or Dzierzon ['d???r???], also John Dzierzon (16 January 1811 – 26 October 1906), was a pioneering Polish apiarist who discovered the phenomenon of parthenogenesis in bees and designed the first successful movable-frame beehive.
Dzierzon came from a Polish family in Silesia.
Trained in theology, he combined his theoretical and practical work in apiculture with his duties as a Roman Catholic priest, before being compulsorily retired by the Church and eventually excommunicated.
His discoveries and innovations made him world-famous in scientific and bee-keeping circles, and he has been described as the "father of modern apiculture".
