**Grigori Yakovlevich Perelman** is a Russian mathematician who was born on 13 June 1966 in Leningrad, the Soviet Union to Russian-Jewish parents. He made great contributions to geometric topology and Riemannian geometry.

Her mother, Lyubov was a mathematic graduate, but she gave up to raise him.

He was a bright student. From the age of 10, he started showing his mathematical skill to the world. His mother, after-school mathematics training program, enrolled him in Sergei Rukshin. At the Leningrad Secondary School, he continued his mathematical education. This is a specialized school where advanced physics and mathematics are been taught. Grigori outshined in all subjects excluding physical education.
