  "summary": "A doctor from Menorca who graduated at Barcelona in 1936, set fractures through the Civil War, crossed into France with a convoy of wounded in 1939 and practised two years in rural Mexico before reaching Iowa, found that clubfeet could be corrected by serial plaster casts, a small tendon cut and a brace, rather than by the surgery that left adults with stiff and painful feet. He published in 1963 and was ignored for thirty years. Evidence of the method is now recorded in 113 countries.",

This object binds that path to the memorial literature, gives the global figures with the survey's own admission of what it could not measure, and - unusually for writing about a celebrated method - puts the trial that found the French functional method equally effective in the claims rather than in a footnote.",
