Jan Dzierżon (also Johann Dzierzon or Johannes Dzierzon) , (16 January 1811 – 26 October 1906) was an Upper Silesian Roman Catholic, temporarily Old Catholic, priest of ethnic Polish descent and a distinguished apiarist who was best known for his discovery of parthenogenesis among bees, and for designing the first successful movable-frame beehive.

Biography

Jan Dzierżon was born and died in Łowkowice (German:Lowkowitz) near Kluczbork (Kreuzburg) in Silesia, Kingdom of Prussia (later Germany). Dzierzon wrote his own biography in 1889 , which was printed in the 1906/7 editition of the Jahresbericht der Schlesischen Gesellschaft fuer vaterlaendische Kultur. He is described by Encyclopedia Britanica (2007) and many other sources as an ethnic Pole and he considered himself a member of the Polish nation, as he was member of native Silesian Polish family.His parents did not speak German. His mother's name was Maria z Jantosiów (Polish surname: Jantos); after completing Polish elementary school he was sent to a Protestant one located a mile away from his village. In 1822 he moved to Wrocław (Breslau), where he attended a middle school commonly know in that area as a gymnasium. In 1833, he graduated from the Faculty of Catholic Theology of the Breslau University, and, in 1834, became chaplain in Siołkowice (Schalkowitz). As an ordained Roman Catholic priest he took over a parish in Karłowice (Karlsmarkt) in 1835. Years later his religious authorities took offence at his scientific research and retired him in 1869.

In his apiary, Jan Dzierżon studied the social life of honeybees and constructed several experimental beehives. In 1838, he devised the first practical movable-comb beehive, which allowed manipulation of individual honeycombs without destroying the structure of the hive. The correct distance between combs had been described as 1 and ½ inches from the center of one top bar to the center of next one. In 1848 Dzierzon introduced grooves into the hive’s side walls replacing the strips of wood for moving top bars. The grooves had been 8 × 8 mm—exact average between ¼ and ⅜ of an inch, which is range recently called bee space. His design quickly gained popularity in Europe and North America. On the basis of the aforementioned measurements, August von Berlepsch (May 1852) in Thuringia and L. L. Langstroth (October 1852) in the United States designed their frame-movable hives.

In 1835, Dzierżon discovered that the drones are produced from unfertilized eggs. The discovery was publicized in 1845. His results caused a revolution in bee crossbreeding. In 1854, he discovered the mechanism of secretion of the royal jelly and its role in the development of queens.

In 1872, Dzierżon received a honoris causa doctorate from the University of Munich. In 1874, he moved back to Łowkowice. From 1873 to 1902 Dzierżon, a sympathizer of Döllinger, was a member of the Old Catholic Church, but in 1905 he was reconciled to the Roman Catholic Church, after a series of theological debates with curate Szoltysek of the Roman Catholic parish of Łomkowice in Upper Silesia.

Legacy

Painting from 1936

Jan Dzierżon is the father of modern apiology and apiculture. All modern beehives are descendants of his design.

Dzierżon considered himself a Pole and was born to Polish parents, although several modern English language sources call him German. Others call him an ethnic Pole recalling his statement that he is a member of the Polish nation, having been born to ethnically Polish parents. Some sources also stress his region of birth (Silesia), and refer to him as Silesian.

In 1936, his village of birth, Łowkowice (Lowkowitz), was renamed by Nazi Germany to Bienendorf (German for "Bee Village") and kept the name until 1945. It was renamed Łowkowice after the region came under Polish control following World War II.

Also, after 1945, the town of Reichenbach im Eulengebirge was first renamed Rychbach, then Dzierżoniów in Dzierzon's honor. In 1962, a Jan Dzierżon's Museum of Apiculture was established in Kluczbork (Kreuzburg). Another was established in the town of Maciejów.

Jan Dzierżon received many honors, among them the Austrian Order of Franz Joseph, the Bavarian Merit Order of St. Michael, the Hessian Ludwig Order, the Russian Order of St. Anna, the Swedish Order of Vasa, the Prussian Order of the Crown (4th Class) at his 90th birthday, and many more. He was an honorary member of the German Academy of Sciences Leopoldina, among others. Dzierżon received an honorary diploma at Graz, presented by Archduke Johann of Austria. In 1903 he was presented to Emperor Franz Joseph I of Austria. In 1904 he became an honorary member of the Schlesische Gesellschaft für vaterländische Kultur ("Silesian Society for Fatherland Culture").
