Andrey Kolmogorov was a Russian mathematician who is known for his path breaking contributions to numerous branches of mathematics and other fields of sciences including, probability, harmonic analysis, information theory, set theory, and number theory. There is no doubt that he is one of the most prominent mathematicians of the twentieth century. In fact, his contributions to probability theory are often compared to Euclid’s contributions to geometry. The greatness of Kolmogorov can also be gauged by the fact that he made significant contributions to not only mathematics but also physics, history, linguistics, and even poetry. From 1923 to 1977 he wrote more than 500 articles and books. He studied every branch of mathematics with the exception of number theory. His studies provided deep insights into mathematics and started new investigative fields in mathematics. He also played a key role in the education reforms in Russia. He was awarded numerous awards and honors, including Stalin Prize (1941), Balzan International Prize (1962), Lenin Prize (1965), Wolf Prize (1980), and Lobachevsky Prize (1986). He was also elected to many academies and societies including, Royal Society of London, Indian Statistical Institute, the American Academy of Arts and Sciences, and the French Academy of Sciences.
