Jan Dzierżon (known also as: Johann Dzierzon or Johannes Dzierzon, 16 January 1811 – 26 October 1906) was a Polish[1], Roman Catholic priest and a distinguished apiarist who was best known for his discovery of parthenogenesis among bees, and for designing the first successful movable-frame beehive.

Early life

Jan Dzierżon was born and died in Łowkowice (German:Lowkowitz) near Kluczbork (German:Kreuzburg) in Silesia, Kingdom of Prussia (later part of Germany).

Dzierżon is variously described as a Pole [2][3][This quote needs a citation] [4][5][6], a German,[7] or a Silesian. He considered himself a member of the Polish nation,[1][8] as he was member of a native Silesian Polish family. His parents who did not speak German[9][This quote needs a citation] were also Polish.[8][10][This quote needs a citation]. His mother's name was Maria z Jantosiów (Polish surname: Jantos);[11][This quote needs a citation]

After completing Polish elementary school he was sent to a Protestant one located a mile away from his village[12][This quote needs a citation] . In 1822 he moved to Breslau (Wrocław), 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.[13][This quote needs a citation]

Professional career

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 published in 1845. The publication, which remained controversial until 1906, proposed that while queen bees and female worker bees were the result of fertilization, drones were not, and that the diets of immature bees contributed to their subsequent roles.[14] His results caused a revolution in bee crossbreeding and may have influenced Gregor Mendel's pioneering genetic research.[15] In 1853, he acquired a colony of Italian bees to use as genetic markers in his research, and sent their progeny "...to all the countries of Europe, and even to America."[16] 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.

Jan Dzierżon is the father of modern apiology and apiculture. Most modern beehives are derived from the basis of his earlier design. The correct distance between combs was described in 1845 by Jan Dzierżon as 1½ inches (3.81 centimeters) from the center of one top bar to the center of the 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 called bee space.

In 1936, his birthplace, Łowkowice (Lowkowitz), was renamed by the Nazi regime to Bienendorf (German for "Bee Village").[17] 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[3]. In 1962, a Jan Dzierżon's Museum of Apiculture was established in Kluczbork (Kreuzburg).

Jan Dzierżon received several 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. He also received an honorary diploma at Graz, presented by Archduke Johann of Austria. In 1903 Dzierżon 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").
