Lewis Terman imported and revised Binet’s tests and launched a gifted-child research industry. Leta Hollingworth, working in New York, described the educational and emotional needs of highly accelerated children with more classroom grain than Terman’s eminence project.
The timeline below follows dated arguments and institutions, not a national myth of genius and not a group ranking.
Origin
1910s–1920s · United States — Lewis Terman imported and revised Binet’s tests and launched a gifted-child research industry. Leta Hollingworth, working in New York, described the educational and emotional needs of highly accelerated children with more classroom grain than Terman’s eminence project.
Timeline
- Binet–Simon scale
Alfred Binet and Théodore Simon build a test to find children who need help in Paris schools — not to crown a caste.
- Stanford–Binet
Terman’s revision spreads IQ language through US schools and his later gifted longitudinal study.
- Hollingworth’s Gifted Children
Leta Hollingworth publishes classroom-near descriptions of highly able children in New York.
- Terman’s Termites
Genetic Studies of Genius begins following high-IQ Californians for decades.
- SMPY founded
Julian Stanley starts the Study of Mathematically Precocious Youth at Johns Hopkins.
- Three-ring conception
Joseph Renzulli publishes the ability × commitment × creativity model.
- Gagné DMGT
Françoys Gagné distinguishes gifts from talents and names catalysts — a Canadian model widely taught in gifted education.
- Winner’s Gifted Children
Ellen Winner synthesises uneven development and the myth of the global gifted child.
- CTY expansion
Johns Hopkins Center for Talented Youth industrialises above-level search beyond Stanley’s first cohorts.
- Twice-exceptional focus
Research and advocacy name students who are both highly able and disabled — a hole in cutoff-only systems.
Eras
- Binet’s brief — Find who needs help — The French origin is remedial, not aristocratic.
- Terman decades — IQ as destiny story — A huge US longitudinal file, a narrow social world, and a public myth of stable genius.
- Hollingworth classroom — Needs, not trophies — Acceleration, peers and emotional intensity enter the literature.
- Model era — DMGT and three rings — Education programmes finally get diagrams that are not a single number.
- Search industrialisation — SMPY / CTY / TIP — Above-level testing becomes a US talent-search product with access questions attached.
Shifts
- From IQ gate to profile 1978–2000s — Renzulli and Gagné made commitment and catalysts official, even where schools still use cutoffs.
- From global gift to domain 1990s– — Maths search, music conservatoires and writing workshops stop pretending one score covers all.
- From prestige to mismatch 2000s– — Twice-exceptional and under-referred students force the field to look at who never gets tested.
Giftedness: keep the dates visible. Names of talents are younger than the work they try to capture.
