**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.

## Grigori Yakovlevich Perelman life Milestones:

- In 1982, he won a gold medal while competing in the International Mathematical Olympiad as a member of the Soviet Union team. He was competing with international high school students.
- In the late 1980s and early 1990s, with a powerful endorsement from the geometer Mikhail Gromov, He got research positions at numerous universities in the United States.
- In the 1990s, he made prominent contributions to the subject of Alexandrov spaces.
- After his PhD in 1990, He began to work at the USSR Academy of Sciences at the Leningrad Department of Steklov Institute of Mathematics.
- In 1991, for his work on Aleksandrov’s spaces of curvature, At the St. Petersburg Mathematical Society, he got the Young Mathematician Prize.
- In 1992, he was invited as a mathematics guest lectures in Stony Brook University and New York University. This is where he started working on Ricci curvature.
- In 1993, At the University of California, Berkeley, he received Miller Research Fellowship for two-years.
- In 1994, he proved the soul conjecture in Riemannian geometry.
- In 1994, he got many job offers from top universities like Stanford and Princeton, but he rejected them all.
- In 1995, To continue his research work, He returned to the Steklov Institute in Saint Petersburg.
- In November 2002, He gave the first of three preprints to the arXiv.
- In 2002 and 2003, he developed new techniques in the analysis of Ricci flow, and presented a detailed picture of a proof of Thurston’s geometrization conjecture,
- In August 2006, for Perelman’s revolutionary insights into the geometric structure and the analytical and of the Ricci flow and his contributions to geometry, he was offered the Fields Medal.
- On 22 December 2006, the Scientific Journal
*Science*appreciated Perelman’s proof of the Poincaré conjecture as the scientific “Breakthrough of the Year”. - This is the first such recognition in the field of mathematics.
- On 18 March 2010, It is said that he was about to get the first Clay Millennium Prize for solving the Poincaré conjecture.
