Aleksandr (Alexander) Semenovich Kronrod (Russian: Алекса́ндр Семёнович Кронро́д) (October 22, 1921 – October 6, 1986) was a Soviet mathematician and computer scientist, best known for the Gauss-Kronrod quadrature formula which he published in 1964. Earlier, he worked on computational solutions of problems emerging in theoretical physics. He is also known for his contributions to economics, specifically for proposing corrections and calculating price formation for the USSR. Later, Kronrod gave his fortune and life to medicine to care for terminal cancer patients. Kronrod is remembered for his captivating personality and was admired as a student, teacher and leader.
He is the author of several well known books, including "Nodes and weights of quadrature formulas. Sixteen-place tables" and "Conversations on Programming". A biographer wrote Kronrod gave ideas "away left and right, quite honestly being convinced that the authorship belongs to the one who implements them."
Kronrod was born in Moscow. Growing up, he studied math with D. O. Shklyarsky in school and in 1938 entered the Department of Mechanics and Mathematics at Moscow State University. He did his first independent mathematical work as a freshman with Professor A. O. Gel'fond. Kronrod was honored as a student with the first prize of the Moscow Mathematical Society and was the only person to win the prize twice.
During World War II he was rejected for military service because at the time graduate level students were exempt. They did help to build trenches around Moscow, and when he returned, Kronrod reapplied and was accepted. He served twice, and was injured twice. He was awarded several medals, including Order of the Red Star and Order of the Patriotic War. The second injury in 1943 hospitalised him for a year and he was discharged from the army in 1944. This injury made him an invalid of sorts for life.
