This Festschrift has been published in honor of Rinus Plasmeijer, to celebrate the combined occasion of his 61st birthday and the 25th Symposium on Implementation and Application of Functional Languages, IFL 2013, held in Nijmegen, The Netherlands, in August 2013. Rinus Plasmeijer was the main designer of the lazy functional programming language "Clean" and has always been the leader of the associated research team. He has played a decisive role in making the Radboud University of Nijmegen an important center of research in functional programming by organizing and hosting the first few IFL symposia in Nijmegen. This Festschrift contains 19 scientific essays written by former PhD students of Rinus Plasmeijer and researchers in the field of functional programming who have collaborated with him. The authors write about the influence the beauty of functional programming has had or still has on their work.

Die Geschichte vor, während und nach dem Zweiten Weltkrieg war auch in der neutralen Schweiz geprägt durch die Wirtschaftskrise, durch Militärdienst und Lebensmittelrationierungen, durch technische Entwicklungen und durch die Aufbruchstimmung nach dem Krieg. Für diejenigen, die sie erlebt haben, fand diese Geschichte in kalten, verdunkelten Wohnzimmern statt, im engen Luftschutzkeller, beim Radiohören mit der Familie, mit dem ersten Chewing Gum und mit dem ersten, einzigen Auto im Quartier. 28 prominente Zeitzeuginnen und Zeitzeugen schauen zurück und erzählen in ihren Beiträgen davon, wie sie den Krieg und die Vor- und Nachkriegszeit als Kinder und Jugendliche erlebt haben. Ihre persönlichen Geschichten und Schilderungen des Alltags lassen die Vergangenheit lebendig werden und hinterlassen einen fesselnden Eindruck vom Lebensgefühl jener Zeit.
