Where the conditions came from
Three sources, read side by side
Each is placed on a −1 to 3 scale from documented evidence, and the three are never added together. A combined total would rank Gilles Brassard against other people. Held apart, they explain why this path ran differently from another one—which is the only comparison this project supports.

What capability, drive, or early skill is documented in the person rather than their surroundings?
Older brother Robert taught him advanced math concepts from an early age. Entered University of Montreal at 13, BSc at 17, MSc at 20. Exceptional early university entry showing strong early ability.

What money, family standing, network, or permission was already in place before the work began?
Older brother sparked passion for math. No evidence of wealthy or academic parents. Montreal, Canadian family. Brother's mentorship was the key family advantage.

What place, timing, institution, or peer group made the next step available?
University of Montreal for BSc and MSc, Cornell PhD under John Hopcroft (Turing Award winner). Met Charles Bennett at a conference in 1979, launching quantum cryptography collaboration. Strong advisor and serendipitous collaboration.
A −1 is a documented headwind, not a missing value; a 0 means the sources record nothing notable either way. Annotation confidence: Medium. 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
Perseverance and luck stay visible—not scored.
Documented perseveranceNot documented in the reviewed biographical summaries.
Silence in a biography is not evidence that perseverance was absent.
Encounter luckMet Charles Bennett at a conference in 1979, launching quantum cryptography collaboration.
This is an unchosen opening or condition in the record, not an estimate of how much luck caused the outcome.

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.

04 Observed career standing
T1 · Global icon
Legendary or globally iconic career standing. The tier summarizes documented career recognition through the data cutoff—not Gilles Brassard's worth or future potential.
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.
Started serious reps before 201/1
Advantage-enabledmedium confidence
One or more documented starting advantages plausibly enabled this lever.
One or more documented starting advantages plausibly enabled this lever.
Elite institution pipeline (2/2)
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Gilles Brassard's outcome attributable to any origin.
Luck is not a leftover score.
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.
Within Researchers / independent engineers, Gilles Brassard's starting-advantage total is at the 56th percentile. Separately, their built or converted leverage total is at the 92th percentile. Other T1 profiles average 8.7 / 24 starting advantage and 13.6 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.

Family context
Born in Montreal, Quebec, Canada; family background not detailed.
Brassard earned his BSc at 17 and MSc at 20 from the University of Montreal, then his PhD from Cornell at 24 in 1979 under John Hopcroft (Turing Award winner). He later co-invented the BB84 quantum cryptography protocol.
