Following his death, his grieving troops composed a song in his honor. However, a famous line on his tombstone; "If he weren't dead, he would still be envied" ("S'il n'était pas mort, il ferait encore envie"), was misread centuries later as: "If he weren't dead, he would still be alive" ("S'il n'était pas mort, il serait en vie"). This is where the French word lapalissade (and the English derivative "lapalissian") comes from.- 25:19, Teodora Groza's PhD thesis on 'Governing Innovation: Antitrust and the Organization of Industry': https://sciencespo.hal.science/tel-05379990.
