Michel Rolle (French mathematician) is the best known by our measure: 33 Wikipedia and sister-site articles in different languages. Next come Pierre-Loup Rajot and Agnelle Bundervoët.
28 people born in Ambert have a French Wikipedia article that confirms the town as their birthplace (and an English one that agrees, when there is one). Wikidata places 45 people here; the rest aren’t listed because an article names somewhere else or no town, or a check couldn’t be completed.
Among its famous people, leaders: 12 of the 28. That is 43% of the town’s list, against 24% across French towns.
Michel Rolle, born in 1652. The youngest on the list was born in 1979.
People whose Wikidata birthplace is Ambert itself, matched by its INSEE code (a commune merged into it counts when the dates allow), whose French Wikipedia article agrees, and their English article too when they have one. A hospital or neighbourhood recorded without its commune isn’t matched. People who only lived here, adult performers and people known mainly for crimes aren’t listed.
Their Wikidata birthplace may be a hospital, a neighbourhood or a wider area, another commune, or missing, or their articles may not name a birthplace. We only list people the sources agree on; editing Wikidata or Wikipedia changes this page at the next refresh.
From Wikidata (CC0: birthplaces, descriptions, years, occupations, how many Wikipedia and sister-site articles cover each person) and French and English Wikipedia (each person’s articles confirm the birthplace; linked, not quoted). Birthplaces are matched to the commune by INSEE code and its history of mergers (INSEE COG 2026). Ranked by the number of articles. Fields are read from Wikidata’s description and occupations. “The usual town”: everyone listed across French towns.
