Mémoire sur l’auscultation appliquée à l’étude de la grossesse.

Although not the first to record the auscultation of the fetal heart sound, Le Jumeau (Kergaradec), a pupil of Laennec, brought the importance of this diagnostic procedure to the notice of the medical profession. Laennec reprinted Le Jumeau's paper in the later editions of De l’auscultation médiate (No. 2673).
