August Froriep (1849–1917) was a German anatomist at Tübingen and a student of the great Jacob Henle (1809–1885). Froriep is known for his studies on the morphology and embryology of the head and vertebrae, and his descriptions of the temporary aggregation of neurons at the root of the embryonic hypoglossal nerve, known today as Froriep’s ganglion. 

In 1882, Froriep and Henle’s former students gathered in Gottingen to commemorate the 50th anniversary of Henle’s doctorate and present him a gift, Beiträge zur Anatomie und Embryologie (Contributions to Anatomy and Embryology), a book composed of chapters written by his students. The book included the classic paper by Froriep on the development of the notochord, which contained six beautifully crafted illustrations of this developmental anatomy. The present book is the first English transla-tion of Froriep’s paper as it appeared in Contributions to Anatomy and Embryology as a Gift to Jacob Henle, On April 4, 1882, Presented by his Pupils. Froriep’s black-and-white illustrations of notochordal development are reproduced in color.
