Walter Jakob Gehring (20 March 1939[2] – 29 May 2014[3])[4] was a Swiss developmental biologist who was a professor at the Biozentrum Basel of the University of Basel, Switzerland. He obtained his PhD at the University of Zurich in 1965 and after two years as a research assistant of Ernst Hadorn he joined Alan Garen's group at Yale University in New Haven as a postdoctoral fellow.[5]
In 1983 Gehring and his collaborators (William McGinnis, Michael S. Levine, Ernst Hafen, Richard Garber, Atsushi Kuroiwa, Johannes Wirz), discovered the homeobox, a DNA segment characteristic for homeotic genes which is not only present in arthropods and their ancestors, but also in vertebrates including man.[9]
Gehring was also involved in the development and application of enhancer trapping methods. He and his collaborators identified PAX6 as a master control gene for eye development, which led to a new theory about the monophyletic origin of the eyes in evolution.[10]
