He said, "So you know how we finish each others' sentences?"

Karl Ernst von BaerDied 28 Nov 1876 at age 84 (born 29 Feb 1792). German-Russian embryologist who discovered the mammalian egg (1827) and the notochord. He established the new science of comparative embryology alongside comparative anatomy with the publication of two landmark volumes (in 1828 and 1837) covering the range of existing knowledge of the prebirth developments of vertebrates. He showed that mammalian eggs were not the follicles of the ovary but microscopic particles inside the follicles. He described the development of the embryo from layers of tissue, which he called germ layers, and demonstrated similarities in the embryos of different species of vertebrates. He was also a pioneer in geography, ethnology, and physical anthropology. |
