Documented path
Perelman's mathematical talent was apparent by age 10, when his mother enrolled him in Sergei Rukshin's after-school mathematics program. He attended Leningrad Secondary School 239, a specialized math and physics school, won a perfect-score gold medal at the 1982 IMO at 16, and continued at Leningrad State University before completing his PhD in 1990 under Aleksandr Aleksandrov and Yuri Burago.
Born in 1966 in Leningrad (St. Petersburg), Soviet Union; parents were Jewish; father was an electrical engineer who emigrated to Israel.
Reclusive Russian mathematician living in St. Petersburg; refused both the Fields Medal and the $1 million Clay Millennium Prize for solving the Poincare conjecture.
Where the conditions came from
Each is placed on a −1 to 3 scale from documented evidence, and the three are never added together. A combined total would rank Grigori Perelman against other people. Held apart, they explain why this path ran differently from another one—which is the only comparison this project supports.
The marble itself
+3Tailwind
What capability, drive, or early skill is documented in the person rather than their surroundings?
Prodigy-level: mathematical talent apparent by 10, won IMO gold medal with perfect score of 42/42 at 16. Rare trajectory-changing ability recognized early. Father also encouraged problem-solving skills and taught him chess; mother nurtured mathematical development.
Where it was dropped
+1Tailwind
What money, family standing, network, or permission was already in place before the work began?
Mother taught mathematics at a technical college and had abandoned her own graduate math study to raise him — she actively nurtured his mathematical talent. Father was an electrical engineer. Educated Jewish family in Leningrad, though not wealthy. Jewish identity created some discrimination in Soviet academia.
The shape of the track
+3Tailwind
What place, timing, institution, or peer group made the next step available?
Sergei Rukshin's intensive after-school mathematics program from age 10. Leningrad's Specialized Mathematics and Physics School Number 239. PhD under Aleksandr Aleksandrov and Yuri Burago at Leningrad State University. Once-in-a-generation math education pipeline.
A −1 is a documented headwind, not a missing value; a 0 means the sources record nothing notable either way. Annotation confidence: High. These are analyst readings of what the sources record, not measurements of merit, talent, or effort. The twenty-two scored dimensions remain available inside the deeper research detail.
What moved through the conditions
This records repeated behaviour or recovery described by sources; it is not a grit or merit score.
This is an unchosen opening or condition in the record, not an estimate of how much luck caused the outcome.
Strongest documented signals: Elite institution pipeline, Frontier geography, Dedicated mentor / coach.
Describes the starting position, not what the person later made of it.
Strongest observed levers: Prior reps, Scarce skill depth, Domain proximity.
Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
The timeline below shows the sequence of work and transitions around the selected early milestone. It is evidence of a path, not proof that every step was necessary.
Legendary or globally iconic career standing. The tier summarizes documented career recognition through the data cutoff—not Grigori Perelman's worth or future potential.
Question four · where did the leverage come from?
Each non-zero lever gets a best-supported origin, evidence signals, and confidence. Unresolved is the honest default when the biography cannot distinguish self-built, advantage-enabled, earned, external, or mixed.
One or more documented starting advantages plausibly enabled this lever.

A structural wave is external to the person, even when their position improved access to it.
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Grigori Perelman's outcome attributable to any origin.
Structural luck, Encounter luck, Event luck, Outcome variance can change every arrow in the path. This successful-only dataset cannot observe the near-identical paths that did not break through, so luck stays visible and unscored.
Multiplying capacity documented later in the path. Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
Access or conditions documented near the beginning of the path. Zero means "no clear evidence in reviewed sources," not "advantage was absent."
Perelman was born to Jewish parents in Leningrad. His mother Lyubov gave up graduate work in mathematics to raise him, creating a mathematically oriented household. His father Yakov later moved to Israel. The family's Jewish identity in the Soviet Union may have created institutional friction.
His mother Lyubov was a mathematician who sacrificed her own graduate studies to raise him, providing early mathematical exposure. His father Yakov's profession is not documented in reviewed sources.
Perelman's mathematical talent was identified at age 10 by his mother, herself a mathematician who had abandoned graduate study, who enrolled him in Sergei Rukshin's intensive after-school mathematics program. He attended Leningrad's specialized School 239 and won a perfect-score gold medal at the 1982 IMO at 16. He was then embedded in the Leningrad mathematical tradition under Aleksandr Aleksandrov and Yuri Burago, with Mikhail Gromov as a key recommender. His mother's mathematical background provided early domain exposure, though no financial advantage is documented. Being Jewish in the Soviet Union may have created institutional friction that sharpened his focus.
