HistoryNamed after Jacob Winslow (1669-1760), a Danish-born French anatomist who received his degree from Ole Borch’s College in 1693, while training under barber-surgeon Johannes de Buchwalde. He would concentrate on anatomy, instead of surgery, as the site of blood “alarmed him”. He would go on to train with many of the most revered surgeons and anatomists of his time while traveling Europe and was widely regarded as the greatest European anatomist of his day. His career would culminate in achieving professor anatomicus and full professor of anatomy at Jardin du Roi in 1743. His most famous work entitled “Exposition anatomique de la structure du corps humain” was published in 1732 and was the quintessential anatomical text of the mid-1700’s
