The Sixteenth Colloquiumfest was intended to honour Peter Roquette, his work, and all the good he has done for his students and those who had the pleasure of meeting him and of working with him. The speakers were students or descendants of him, have worked with him or have been close to our Heidelberg group in the 1980s and 1990s. We discussed topics from Arithmetic and Valuation Theory and remembered the historical background and anecdotes that tied these topics to our Heidelberg group.
