Embryology History - Ziegler Models
Introduction
Not a collection as such, but a historic series of wax models made in the 1860-80s based upon the embryos of Prof. Wilhelm His, Leipzig. Wilhelm His had earlier prepared a series of freehand models. These Ziegler models are the basis of some of the teaching models that are still commercially available and used today.
Adolf Ziegler (1820 - 1889) a German modeller developed these models at his Studio for Scientific Teaching Models (Atelier für wissenschaftliche Unterrichtsmodelle) from the 1860's onwards of both human and animal embryos. Ziegler's models were first used in Germany, but were also later exhibited in Paris (1867) and Vienna (1873).
His son, Friedrich Ziegler (- 1936), continued the modelling company.
The Carnegie Institute later in the early 1900's also developed many additional models based upon their own collection. (More? Carnegie Models)

Eye Models
Development history of the eye series 8b consists of 3 models while series 8c consists of 5 models of early eye development.
Series 8b Models 1-3
Series 8b, three wax models, submitted by F. Ziegler, c 1930. Models are made to example of Prof. von Szily. Showing the development of the papilla nervi optici primitiva s. lamina typus "sauger". max. height 18 cm.
Series 8c Models 1-5
Models of the right eye of the developing rabbit embryo.
Series 8c, five wax models, submitted by F. Ziegler, c 1930. Models are made to example of Prof. von Szily. it is a view of the ontogenesis of the idiotype gap formation of the eye of microphthalmia and the orbital cistern. it concerns a rabbit eye. maximum height 32 cm.
Series 8b Model 1
Left primordial eye of 12 days old embryo.
Images show model viewed laterally and from the external and internal view.
