Christian Heinrich Pander

Christian Heinrich von Pander (Russian: Христиан Иванович Пандер, romanized: Khristian Ivanovich Pander; 24 July [O.S. 13 July] 1794 – 22 September [O.S. 10 September] 1865), was a Russian biologist and embryologist of Baltic German origin. He was among the first to identify distinct germ layers involved in the development of the embryo, coining the term "blastoderm". He has been considered as a "father of embryology" but he also worked on comparative anatomy, studying the skeletons of vertebrates, as well as fossils and geology.
