Fossils unearthed in Peru have led scientists to conclude that the enormous creatures that traverse the planet’s oceans today are descended from small hoofed ancestors that lived in south Asia 50 million years ago, A scientist has stumbled upon a creature with a “transient anus” that appears only when it is needed, before vanishing completely. Heinz is a chemist, and taught me to think in quantitative terms, yields, completeness of reactions, he is an excellent experimenter. This was supported by my parents by giving me the right books, and by my brother and sisters by listening to my tales and theories. The obvious groups of phenotypes were readily analyzed, what was more difficult was to take care of all the other mutants (more than 300 total) we had collected. However, as the animal gets full, a pore opens up to dispose of waste, Feared extinct, the Wallace's Giant bee has been spotted for the first time in nearly 40 years. Kathryn Anderson, later Siegfried Roth and Dave Stein, studied the dorsal group genes including cactus, Ruth Lehmann concentrated on the posterior group, and Hans Georg Frohnhöfer on the anterior mutants. Both Eric and I got a job offer from John Kendrew, the director general of the European Molecular Biology Laboratory in Heidelberg, that was newly founded and recruiting in many areas. It also led to a very detailed examination and description of the segmental pattern of the Drosophila larva which we later used in our screens. As students, Hans Georg Frohnhöfer and Ruth Lehmann started during the first year. Via the class in chemistry I got reminded of my true interests in biology. The improvements in the techniques of visualisation of the gene products by in situ hybridisation and antibody stainings complemented the transplantation studies done earlier, resulting in several exciting discoveries concerning the establishment of gradients in the extracellular space and by nuclear localisation by Dave Stein and Siegfried Roth. Wolfgang established many molecular methods in my lab, and subsequently Frank Sprenger and Leslie Stevens cloned torso, followed by Daniel St Johnston with the cloning of staufen, and Robert Geisler’s cloning of cactus. I looked around and sought advise from two of the hydra people, the American postdocs Hans Bode and Charles David. Scientists apparently did not deliberately make mutations until … NobelPrize.org. Admittedly, we also did not have great interest in what other people were doing at the EMBL, it was so far from our work and we had so little time, but we enjoyed the international atmosphere and were good citizens of the place. We moved across the yard in 1986. These efforts resulted in the building of a fish house, with 7000 aquaria of our design, inaugurated in September 1992. For the discovery of genes that control development in animals and humans, and the demonstration of morphogen gradients in the fly embryo, she received a number of awards and honours, among others the Albert Lasker Medical Research Award (New York/USA) and in 1995 the Nobel Prize in Physiology or Medicine together with Eric Wieschaus and Edward Lewis. Scientists use a variety of laboratory techniques to investigate the genetic cause of human diseases. My mother had great social talents and a very good way of taking care of children, and other people who needed help, in an unassuming and practical way. I met Eric Wieschaus who just had finished his thesis in Walter Gehring’s lab.
