Tuvan Institute for Research in the Humanities is preparing for its 65th anniversary celebration. On October 1, 1945 the Tuvan Research Studies Institute of Language, Literature and History (TRSILLH — presently the TIRH) was established on the basis of the Scientific Committee of the Tuvan People’s Republic. On October 1, 2010 a solemn meeting will take place in the TIRH. It will be dedicated to the anniversary of the institute. Its veterans will be honoured. In the newspapers of the TIRH — “Ertem sozu” and “Slovo Plus” — some memoirs and materials on the history of the institute are being published. They have started the preparation for the opening of memorial plaque devoted to the first director of the institute Leonid Borandaevich Chadamba who was a prominent socio-political figure of Tuva. He was the head of the institute in 1945–1951.
