Savants in 1887: J. Langdon Down’s notes

Islands of extreme skill beside disability — Treffert’s clinic, not a circus and not a superhero genre. Savant syndrome is a clinical pattern: extraordinary skill in a narrow island — calendar, music, drawing, calculation, memory — beside significant disability in other areas. Darold Treffert spent decades insisting on respectful description. Kim Peek, Leslie Lemke, Stephen Wiltshire, Derek Paravicini and historical cases like Gottfried Mind are documented lives, not acts. The skill is typically not a school “gifted” profile and does not transfer widely — hence the low transfer and trainability scores.
