Introduction
The very size and dynamic nature of embryonic development has always made it a difficult topic to teach. The structures are always so small and the changing nature of development means that a feature you identify at any one time is called, and becomes something else, at a later stage.
Models made from ceramic, wax or plastic, not the "animal models", are useful in that they make tangible the microscopic structures to the students. Models have been in use for some time in the medical teaching of human development with the original plaster models now replaced by commercial modern plastic versions. Many of the early teaching models were not about development, but about the process of childbirth for doctor and midwife education.
A historic alternative to the use of teaching models, were series of plates and drawings found in textbooks and papers from the late 19th century onwards. At the beginning of the 20th century photography also came into play, seen mainly associated with embryos within the Carnegie collection.
Some links on this page are to both historic non-commercial and modern commercial suppliers of some education models for embryology. In some cases these are museum exhibits only available for viewing. This list is provided for information purposes only and does not indicate an endorsement of these commercial products.
Historic Models
Galletti Models
Giuseppe Galletti (? - 1819) these models are currently available for viewing at the Institute and Museum of the History of Science (Italy) "Specimens of obstetric models: the wax models are life-sized; the terracotta versions are reduced to a 1:3 scale. Together with the anatomical waxes in the Specola Museum in Florence, these models are among the most significant examples of the use of artistic techniques for teaching medicine and obstetrics to midwives and surgery students in Florentine hospitals at the end of the eighteenth century."

Ziegler Models
Adolf Ziegler (1820 - 1889) a German modeller developed these models at his Studio for Scientific Teaching Models (Atelier für wissenchaftliche 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.

Carnegie Models
One of the first to be hired, in 1913, was modeler Osborne O. Heard, who spent 42 years at the department and made over 700 wax-based reconstructions. The results of this team effort still stand as the international standard by which human embryos are described and classified. The models were mainly made by the lost-wax casting process and his models were also more detailed than the earlier (1880's) Ziegler embryo models.
