The scientist, statesman, academician Albinas Rimka (1886–1944) is famous in Lithuanian historiography as a creator of independent Lithuania. First of all, his merits as a politician and economist are to be mentioned. Albinas Rimka is considered to be the founding father of science of statistics in Lithuania in 1920–1940. In the textbooks on fundamentals of statistics and at lectures which Albinas Rimka delivered at university, the academician based statistical methods upon the main verities of high mathematics including elements of mathematical analysis, theory of probability, and mathematical statistics.
