Etymologically, the entry records: Named after German surgeon Edmund Leser and French surgeon Ulysse Trélat. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is Leser-Trélat sign, spelled L-E-S-E-R---T-R-É-L-A-T- -S-I-G-N, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
