Piet van der Kruit Kapteyn Astronomical Institute, University of Groningen, The Netherlands vdkruit@astro. rug. nl In the rst place I would like to say that I am extremely grateful that this conference took place. It was a very stimulating and exciting meeting. The speakers and contributors to the discussion were all very inspiring and the S- enti c Organising Committee put together a most interesting program. It was also helpful that the meeting was held in the same place where we were st- ing and had our meals, the Schylge Hotel on the beautiful Frisian island of Terschelling. I am very pleased that so many young astronomers took part and made use of the many opportunities at meals and in the evenings to talk to older astronomers. For me personally it was great to see many colleagues that have worked in the same eld as I and whom I often have known and respected for many years. I rst of all would like to thank those former students of mine that took the initiative to hold this symposium and subsequently did most of the hard work of organising it: Erwin de Blok (although really and truly a student of Thijs van der Hulst), Richard de Grijs, Roelof de Jong, Johan Knapen and Eline Tolstoy (whose real supervisor was Abi Saha). In particular I am very grateful to Roelof de Jong, who chaired the Scienti c Organising Committee, designed the poster and the logo and edited these proceedings.
