Introduction
(University of Goettingen, Germany)
The Blechschmidt Collection, named for Erich Blechschmidt (1904 – 1992), developed methods of human embryo reconstruction from serial sections and generated large models describing the embryonic period of human development. The models include whole surface views as well as detailed views of embryo internal structures.
The collection consists of 64 models[1] and approximately 200,000 serial sections of human embryos. Some of these embryo serial section sets were incorporated in 1972 into the Carnegie Collection (assigned Carnegie Nos. 10315-10434), but have since been returned to the University of Goettingen.

Erich Blechschmidt
Erich Blechschmidt (1904 – 1992)[2] was a German anatomist and director of Göttingen University’s Anatomical Institute from 1942 until 1973. He held alternate theories for embryogenesis based upon "morphogenetic fields" and also believed that more than just genes might act to control development. He wrote several embryology books and research articles (32 are listed in PubMed between 1955 to 1976) all originally published in the German language.
