[Karl Ernst von Baer 1792-1876].

Best known for his contributions to the field of embryology [6], Karl Ernst von Baer [5] also pursued a variety of other areas of study including medicine, botany, zoology, and anthropology. Committing his life to scientific research, von Baer?s work led to the advancement of the understanding of mammalian reproduction, development, and organ functioning. His embryological discoveries ultimately led him to a view of development that supported epigenesis [7] and refuted long-held thinking about preformation [8]. Karl Ernst von Baer [5] was born on 28 February 1792 in Piep, Estonia, to first cousins Juliane Louise von Baer and Magnus Johann von Baer. As one of ten children, von Baer spent his childhood in Coburg with his father?s brother Karl and his wife, Baroness Ernestine von Canne.
