Ceska Posta has issued a stamp to commemorate the 150th Anniversary of the Foundation of the Union of Czech Mathematicians and Physicists (JCMF).
JCMF is one of the oldest, still existing learned societies in the Czech Republic. It was founded in 1862 as the Association for Free Lessons in Mathematics and Physics (Union of Czech Mathematicians). Its initial mission was to improve the level of teaching physics and mathematics at all levels of schools of any kind, and to support and further develop these disciplines.
The union was extended in 1869 (Union of Czech Mathematicians and Physicists) due to patriotic tendencies. The Union's members were mostly teachers at high schools or higher education institutes, as well as university teachers and scientists.
In 1870 the Union started publishing a bulletin Zpravy Jednoty ceskych matematiku a fyziku (News of the Union of Czech Mathematicians and Physicists), 2 years later (1872) followed by a journal dedicated to mathematics and physics Casopis pro pestovani matematiky a fysiky (Journal to Foster Mathematics and Physics), the first ever mathematics journal in the Austrian-Hungarian empire. A year later the Union already started publishing textbooks and scientific monographs. Following the formation of an independent Czechoslovakia it gained a de facto monopoly as a qualified publisher of textbooks, scientific books, and journals with mathematical-physical themes. In the early 1950s the Union was forced to transfer its property to the newly set up Czechoslovak Academy of Science, and became one of its learned societies. The mathematics section of its library formed the basis for the resources of the Mathematical Institute's library. The name used by the Union over the periods of 1921-39 and 1945-93 was the Union of Czechoslovak Mathematicians and Physicists.
