A great publisher, who often set the tone during his active professional years, is now retiring. Over the decades Klaus G. Saur has developed and carried out publishing projects of an extent almost unimaginable to us today. An impressive hoard of authors who accompanied Klaus G. Saur on part of his journey, and were an important part of his Berlin years, has put their personal experiences and thoughts to paper on this occasion. The result is a mosaic of encounters, of important and amusing moments, that illustrate the years when Klaus Saur wasChief Executive and Partnerof the publishing house de Gruyter.
