Professor Sándor Csörgő (16 July 1947 at Egerfarmos, Heves County – 14 February 2008 at Újszeged, Csongrád County[1]) was a Hungarian mathematician, and a professor at the University of Szeged.
His main fields were probability, mathematical statistics, and asymptotic theory. He did important research on the St. Petersburg paradox.
He was a member of the Hungarian Academy of Sciences.
His brother Miklós Csörgő was also a mathematician.
Csörgő graduated from the István Dobó High School in Eger, Heves County. He did undergraduate studies in the mathematics department at József Attila University (University of Szeged), graduating in 1970, and immediately joined the János Bolyai Mathematical Institute at the University as a graduate student. In 1972, he presented his doctoral thesis to Béla Szőkefalvi-Nagy and Károly Tandori.
