Etymologically, the entry records: Named after Gustav Wiedemann and Rudolph Franz. 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 Wiedemann-Franz law, spelled W-I-E-D-E-M-A-N-N---F-R-A-N-Z- -L-A-W, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
