Eric Wieschaus and Christiane Nüsslein-Volhard isolated and characterized many of the genes necessary for early embryonic development in Drosophila.

Eric Wieschaus was born in South Bend, Indiana in 1947. His family moved to Birmingham, Alabama when he was six. He grew up without any special interest in science. He spent his free time painting and sketching; his ambition was to become an artist. This all changed when he participated in a summer program funded by the National Science Foundation. The program brought bright teens together and encouraged them to consider careers in science by sponsoring their internship in science laboratories. Wieschaus enjoyed the camaraderie of fellow students, and was given a chance to work in a neurobiology lab. He didn't believe that what he did in the lab produced much data, but he was so interested in the "scientific" process and interacting with other science "geeks" that he decided to study science in college. Wieschaus went to Notre Dame and majored in biology. As a way to earn money, he took a job making fly food in Harvey Bender's Drosophila lab. Here he learned the basics about fruit flies, but he was much more interested in embryology, and questions like: "how do cells know what to do as an embryo develops?", "what drives differentiation and development?" Wieschaus thought he might not have a chance to find out because just as he was finishing college, the Vietnam War started. He applied for conscientious objector status, and decided to go to graduate school at Yale University while he waited to see if he would be drafted. Harvey Bender intervened on his behalf and wrote to Donald Poulson, a Drosophila geneticist at Yale. Poulson took Wieschaus on as a grad student sight unseen. It was a stroke of luck to be in Poulson's lab because Poulson did a lot of the work on Drosophila embryogenesis. Poulson was about to retire, so Wieschaus wasted no time to learn as much as he could from him. After about a year, Poulson sent Wieschaus to Walter Gehring, who was just starting a fly lab at Yale. Poulson was able to retire and Wieschaus found himself in the enviable position of being the only graduate student in a new lab. He and Gehring worked closely together and Wieschaus finished his Ph.D. in 1974. By this time, he was in Basel, Switzerland where Gehring's lab had moved, and Wieschaus planned to go to Zurich, Switzerland, to do post-doctoral work. Before he left, Christiane Nüsslein-Volhard came to Basel and the two of them began talking about possible experiments. In 1978, Wieschaus was offered a job at the newly established European Molecular Biology Laboratory (EMBL) in Heidelberg. Nüsslein-Volhard had been offered a job there as well, and the two of them were able to collaborate on the experiments they had talked about in Basel. They carried out large-scale mutagenesis experiments to find developmental Drosophila mutants. The result of their work was a new understanding of the mechanism involved in early Drosophila development. Wieschaus and Nüsslein-Volhard shared the 1995 Nobel Prize for their work with Ed Lewis. In 1981, Wieschaus accepted a position at Princeton University and he has been there ever since. His research continues to focus on development, specifically on changes in cell shape during the various developmental stages. Wieschaus believes that his early passion for art enhanced his ability as a scientist especially when it comes to "seeing" things. He still paints and does much of the image editing and presentation work of data from his lab. Wieschaus also does all the food preparation for his family, and spends his commuting time - he usually bikes to work - planning nutritious and practical meals.
