Léonard Cruveilhier (1760-1836), Bruno Giraud (1768-1811), Léonard Boudrye (1769-1852). The author deals with their biographies during a period marked by wars. Descended from middle-class and students in Paris they were promoted through campaigns and battles. After the First Empire Boudrye and Cruveilhier took back their medical work in Tulle and Limoges while Giraud was selected by King of Holland, Louis Bonaparte, but unexpectedly died in 1811. Their medical careers were glorious but they were submitted to the consequences of the political changes.
