We all know the feeling: you walk into your kitchen, prepared to start your day, and a cloud of wee annoyances lift off of an overripe banana on your countertop. Your kitchen has been besieged by those unruly, buggy little things we all know as fruit flies. But just imagine if you will, that one of these wee annoyances and instead see the key to understanding just how genetics work. Imagine seeing the beauty and the possibility in a cloud of fruit flies. Well, that’s what our July HerStory recipient, Christiane Nüsslein-Volhard, did. She embraced (not literally, because fruit flies are teensy) the little buggers and figured out how genes control embryonic development.
Born in 1942 in Magdeburg, Germany, Nüsslein-Volhard was a precocious child, always interested in biology and the natural sciences. Her grades throughout primary school were mediocre, as she professed to not give time and energy to the subjects that didn’t interest her. She attended Goethe Frankfurt University in Frankfurt in the early 1960s, but found herself feeling unchallenged and bored, so transferred to the University of Tübingen when they debuted a biochemistry program in the mid-1960s. Tübingen housed the Max Planck Institute for Virus Research, and was host to visiting scientists from a variety of fields, which proved to be inspiring to our young research. While at Tübingen, she briefly married and gained a hyphenated name, but when the marriage ended in divorce, she kept both names, as she
had begun to be published, and preferred the continuity of having the same name. Her PhD work led her to study molecular biology and genetics in more depth, but she found that the course of study she had chosen was limited and not as inspiring as she hoped. She moved on to cellular biology, and studied at the University of Basel in Switzerland for a time, learning more and more about how genes behave, and what effects introducing mutations into a developing embryo have. She moved back to Germany to continue her work on genetics, and in 1980, along with her research partner, published a paper identifying fifteen genes that compromise the fruit fly.
After publishing this seminal paper, in 1986, Nüsslein-Volhard went home, to
Tübingen, Germany, and became the director of the Max Planck Institute for Developmental Biology. She held this position for many years, and continued her work on genetics. Inspired by her genetic discoveries with fruit flies, she began working on isolating genetic structures of vertebrates, and began studying zebrafish. Nüsslein-Volhard also began working on social, ethical, and philosophical issues in the sciences. She served on the National Ethics Council of Germany and became a leader on ethics and gender equality issues. Nüsslein-Volhard established the Christiane Nüsslein-Volhard Foundation, an organization which seeks to promote gender equality in science by providing support and resources to female scientists. One of things that most inspired Nüsslein-Volhard to found this organization was the realization that, no matter how accomplished a female scientist was, at the end of the day, for many women, the burden of homemaking, otherwise known as the invisible workload, most commonly falls to women. Her foundation provides funding resources to help female scientists hire out that invisible workload. She has spoken on the ongoing difficulties women face in the sciences:how hard it is for women to balance research and family obligations, and the fact that this is the leading reason women are so underrepresented in leading scientific positions.
Christiane Nüsslein-Volhard won the Nobel Prize Physiology and Medicine in 1995. She later reflected that it was a double-edged sword: she enjoyed the legitimacy and professional honor, but found it a distraction in many ways. She was torn between feeling the need to accept all invitations to speak and the desire to get back to work, and felt that there was a definite sexist slant to some of the reception to her award. Throughout her career, and throughout the careers of many women in fields that have been dominated by males, she’s had not only to do the work, put in the time, and make sure her work is exemplary, but also to fight against the sometimes-fragile male egos of her contemporaries.
She’s currently Director Emeritus at the Max Planck Institute for Developmental Biology, and in her spare time, loves to cook (she’s even published a cook book!) and play the flute and sing. She continues to be a leader in the field of genetics, and even has an asteroid named after her. So, the next time you find yourself with some overripe fruit and overzealous fruit flies, take a moment before smashing them all to think about how these humble pests helped to further our understanding of how genes work, and inspired the career of a truly inspiring HerStory recipient.
