The Yale Embryo

In 1934 a fourteen-day-old embryo was discovered during a postmortem examination and became famous for being the youngest known human embryo specimen at the time. The embryo was coined "the Yale Embryo," named after the location where it was discovered, Yale University in New Haven, Connecticut. During the early twentieth century, the rush to collect embryos as well as to find younger and younger embryos was at an all time high, and the Yale Embryo is representative of the this enthusiasm.

Washington University in St. Louis

Washington University in St. Louis served as the backdrop for many scientific discoveries, including that of nerve growth factor (NGF). Many of the accomplishments in embryology at Washington University can be attributed to the influence of Viktor Hamburger. He served as chair of the zoology department for twenty-five years. One of the few Nobel Prizes given for embryological research was awarded to faculty members Hamburger hired; Rita Levi-Montalcini and Stanley Cohen won for their role in the discovery of nerve growth factor.

The ruling stemmed from the 1983 case involving an infant born with severe physical and mental congenital defects; the infant was only identified as Baby Jane Doe.

Arizona State University Embryo Project Photograph Collections

In the 1970s Stanford University Embryologist Harold Heath sent a box of photographs to Frederick B. Churchill, who was a Professor in the History and Philosophy of Science Department at Indiana University. Heath was born in Indiana, he knew that Churchill was the leading historian of embryology, and he wanted his photographs to be used and therefore wanted them to be housed somewhere with an interest in the history of biology. Heath made it clear that he was donating the photographs for use by scholars and the public.

Slime mold development video by John Tyler Bonner

1 black and white video ; approximately 6 minutes ; sound; video/mp4; reformatted video

This video is composed of a sequence of time lapse films created by John Tyler Bonner in the 1940s to show the life cycle of the cellular slime mold, Dictyostelium discoideum. As only the second person to study slime molds, Bonner frequently encountered audiences who had never heard of, let alone seen, the unusual organism. He therefore decided to create a film to present at seminars in order to introduce his object of study. Bonner created the video for his senior thesis at Harvard University with the help of photographer Frank Smith.

Meselson, Stahl, and the Replication of DNA: A History of "The Most Beautiful Experiment in Biology" (2001), by Frederic Lawrence Holmes

In 2001, Yale University Press published Frederic Lawrence Holmes' book, Meselson, Stahl, and the Replication of DNA: A History of "The Most Beautiful Experiment in Biology" (Replication of DNA), which chronicles the 1950s debate about how DNA replicates. That experiment verified that DNA replicates semi-conservatively as originally proposed by Watson and Crick. Rather than focusing solely on experiments and findings, Holmes's book presents the investigative processes of scientists studying DNA replication.
