As the science of developmental biology emerged during the 1800s, the need grew for models to demonstrate the intricate details of embryological morphogenesis. The Swiss anatomist Wilhelm His (1831 – 1904) attempted this by collecting embryos and fetuses derived from miscarriage and prenatal deaths. Using large microtome sections and stained glass slides, he was able to prepare a number of freehand designs illustrating normal development. Following His’s instructions, Adolf Ziegler (1820 - 1889) and his son Friedrich crafted a series of wax models, many of which were sold to medical schools around the world. TheÌýmodels shown here were probably made in the late 1800s and acquired by the Ã山ǿ¼é Anatomy Museum in 1914.
