I was pleased to hear that Christoph will move to the EBI early next year. Christoph has been working on Open Source and Open Data chemoinformatics since at least 1997. I first got in contact with Christoph when I wrote code for JChemPaint (which Christoph developed) to be able to read Chemical Markup Languages (CML). This also got me into contact with Dan Gezelter who is the original author of Jmol, to which I also added CML support.
