2016 New Editorship Elisabeth Blum, Jesko Fezer, Günther Fischer, Angelika Schnell. The series, justifiably called legendary, on the history and theory of architecture and urban planning was founded in 1963 by Ulrich Conrads and has been published since the early 1980s together with Peter Neitzke. With over 150 volumes, it is now the most extensive German-language book series on these topics. Following the deaths of the two long-time editors Ulrich Conrads (2013) and Peter Neitzke (2015), a new editorial team has taken over: Elisabeth Blum, Jesko Fezer, Günther Fischer, Angelika Schnell. As future editors, we strive to stay on course. The original aim of the series, to provide an overview of the architectural and urban planning ideas and realizations of the 20th century, has already been achieved in an outstanding manner.
