I felt at the time that Eric was much more successful than I, he was extremely productive during his time in Zurich, and worked on many very original projects, germ line, cell lineage, sex determination, where not many people could follow him. I also had the impression that I was dependent on him because he had more fly experience and without him I would not have gotten the job. This made our start in Heidelberg a little difficult, until we sorted things out, and from then on we thoroughly enjoyed working in the same lab.
