Caesar Albano Kletke

Caesar Albano Kletke (born November 28, 1805 in Brieg ; † April 5, 1893 in Breslau ) was a teacher and schoolmaster.

Life

Caesar Albano Kletke was the son of the businessman Carl Heinrich Kletke and his wife Josefa Schiller. After attending the “Augustum” grammar school in Görlitz , when he was 13, he went to the Maria Magdalenen grammar school in Wroclaw , which was then headed by Johann Kaspar Friedrich Manso . There he excelled especially in mathematics . He passed his school leaving examination in 1823 with distinction. Kletke studied at the University of Breslau . His focus was mathematics, but also philology under Franz Passow and philosophy under Henrich Steffens . A personal relationship developed with him, who was also a natural scientist, as well as with the writer Karl Schall and Johann Theodor Mosewius , the founder of the Breslau Singakademie. Not yet 22 years old, Kletke passed the examination for the higher teaching degree in mathematics, physics , German, philosophy and a number of minor subjects. Kletke did not retire until he was 71. He died at the age of 88.

In 1828 Kletke became a full teacher at the grammar school in Oels and already in 1829 - at the age of only 24 - a teacher at the traditional Wroclaw Elisabet grammar school . From 1833 he was also a private lecturer at the University of Breslau. Kletke qualified as a professor in applied mathematics and also gave many lectures in the “Silesian Society for Patriotic Culture”. At the beginning of the 19th century, the development of industry and trade as well as the expansion of the administration also changed the previously more agriculturally oriented Silesia . But the schools in Wroclaw up to that point no longer met these new requirements.

After overcoming many difficulties, the time had finally come in 1836: The city council of Wroclaw elected Caesar Albano Kletke as the first rector of the new "Citizens' School at the Zwinger". Through Kletke's successful establishment of this new type of secondary school , he became known at home and abroad as their prominent representative and also gave impetus to schools abroad. In 1840, for example, the circumnavigator Adam Johann von Krusenstern , Russian Vice Admiral and Director of the Naval Cadet Corps , visited the school in the Russian capital of St. Petersburg at the time in order to gain educational ideas.

And in 1871 Pyotr Georgiewski, State Councilor in the Russian Ministry of Culture, came to Wroclaw. Following Kletke's suggestions, he then set up secondary schools in Russia. The supraregional reputation of Kletke also contributed to the fact that the Prussian Ministry of Culture commissioned him in 1845 to write a memorandum on the organization of higher middle and secondary schools. In recognition of his services, he was awarded the title of "director" in 1846 (analogous to the designation of the head of the grammar schools in Wroclaw).

Kletke always advocated the so-called " polytechnical education", that is, for practical subjects such as technical drawing or chemistry , and he advocated greater consideration of German teaching than foreign languages ​​for the purpose of formal education. Caesar Albano Kletke was a brother of the historian Karl Kletke and a cousin of Hermann Kletke (1813–1886), writer and editor-in-chief of the Vossische Zeitung in Berlin.
