Named on the cast card scanned with the recording (AubertForetcasttracks.JPG in the folder), the tray insert of the CD carrying the RTF Paris broadcast of Louis Aubert, La Foret bleue, 11 June 1954 under Eugene Bigot. That broadcast is corroborated by https://fr.wikipedia.org/wiki/La_For%C3%AAt_bleue ("Un enregistrement est realise en 1954 avec Martha Angelici et Jacqueline Brumaire notamment"). No standalone biography found; for a French radio singer of this period the cast sheet is the only document.
