**István Vincze** ( (1912-02-26)February 26, 1912 – April 18, 1999(1999-04-18) ) was a Hungarian mathematician, known for his contributions to number theory, non-parametric statistics, empirical distribution, Cramér–Rao inequality, and information theory. Considered by many, as an expert in theoretical and applied statistics, he was the founder of the Mathematical Institute of the Hungarian Academy, and was the Head of the Statistics Department. He also held the post of professor at Eötvös Loránd University. He wrote over 100 academic papers, authored 10 books, and was a speaker at several conferences, including the Berkeley Symposiums in 1960, 1965, and 1970. He received honors and awards like the Hungarian State Prize and Grauss Ehrenplakette in 1966 and 1978 respectively.

Born in Szeged, Hungary, he graduated from the University of Szeged in 1935.

Around 1950, he founded the Mathematical Institute of the Hungarian Academy, whose director was Alfréd Rényi.

Early in his career, he wrote papers with Paul Erdős, including *On the approximation of convex, closed pane curves by multifocal ellipses*.

Some of his books that were translated into English are *Progress in statistics* (1972), and *Mathematical methods of statistical quality control* (1974).

He participated in conferences and gave seminar talks throughout the world, including the United States, Canada, Argentina, Germany, and China.

He retired from academic teaching in 1980, and died in 1999.
