context_page_description: László Rátz, was a Hungarian mathematics high school teacher best known for educating such people as John von Neumann and Nobel laureate Eugene Wigner. He was a legendary teacher of "Budapest-Fasori Evangélikus Gimnázium", the Budapest Lutheran Gymnasium, a famous secondary school in Budapest in Hungary.
context_section_description: The János Bolyai Mathematical Society (Bolyai János Matematikai Társulat, BJMT) is the Hungarian mathematical society, named after János Bolyai, a 19th-century Hungarian mathematician, a co-discoverer of non-Euclidean geometry. It is the professional society of the Hungarian mathematicians, applied mathematicians, and mathematics teachers. It was founded in 1947, as one of the two successor societies of the Mathematical and Physical Society ("Bolyai János Matematikai és Fizikai Társulat") founded in 1891. It is a member-society of the European Mathematical Society. The European Mathematical Society (EMS) is a European organization dedicated to the development of mathematics in Europe. Its members are different mathematical societies in Europe, academic institutions and individual mathematicians. The current president is Marta Sanz Solé, professor of Statistics at University of Barcelona. Some of the Presidents of the Society were György Hajós (1963–1972), László Fejes Tóth (1972–1975), Pál Turán (1975–1976) and János Surányi (1976–1980), the names of some of them are below under Középiskolai Matematikai és Fizikai Lapok, KöMaL.
  János Bolyai Mathematical Society organizes László Rátz Congress for secondary school mathematics teachers every year and has issued the László Rátz coin since 2000. The High School Mathematics Journal was published by the János Bolyai Mathematical Society and the publication was financed by the Ministry of Education.
  János Bolyai (15 December 1802 – 27 January 1860) Hungarian: Bolyai János, was a Hungarian mathematician, one of the founders of non-Euclidean geometry — a geometry that differs from Euclidean geometry in its definition of parallel lines. The discovery of a consistent alternative geometry that might correspond to the structure of the universe helped to free mathematicians to study abstract concepts irrespective of any possible connection with the physical world. Bolyai was born in the town of Kolozsvár (Klausenburg), Principality of Transylvania (now Cluj-Napoca in Romania), the son of Zsuzsanna Benkő and the well-known mathematician Farkas Bolyai. He died in Marosvásárhely, Transylvania, Austrian Empire (now Târgu Mureş, Romania).
