Caspar Friedrich Wolff (1734-1794) was a German embryologist and anatomist best known today for identifying the Wolffian duct (mesonephric duct; ductus deferens, epididymis), Wolffian body (mesonephros) and Wolffian cyst (mesonephric origin uterine broad ligament cyst) that bear his name. Thought also to be a founder of the germ layer theory. His doctorate dissertation Theoria generationis (1774) discarded the developmental theory of preformation. Later in his career, his teaching in Berlin was opposed by the professors of the Medical-Surgical College, who had guild privileges to teach medicine.
