Who is the father of modern embryology?

Karl Ernst von Baer (1792-1876), commonly referred to as K.V. Baer, is widely regarded as the father of modern embryology. He discovered the mammalian ovum (egg cell) and established the germ layer theory, showing that early embryos of different vertebrates are remarkably similar (von Baer's laws). Theophrastus studied botany, while Darwin and Lamarck are known for evolutionary theory, not embryology.
