"This book is very appropriate for a study of the role of science in this period of Barcelona’s history. It is much more than a collective volume; it is an impressive academic collaborative effort. At the same time, it is generally a very accessible, easy read and very rich and diverse in the topics addressed, in the sources and approaches used, and in its analyses of Barcelona’s history. (...) This book is a major contribution to existing scholarly works in several areas: General History of Barcelona, History of Science in Barcelona and the relation between Urban Studies and History of Science. The contributions suggest a great amount of work behind them and clearly show how science was practised, taught, popularized, used and even sold in this period in Barcelona."- Miquel Carandell Baruzzi, Universitat Autonoma de Barcelona – Centre d’Historia de la Ciencia CEHIC in Metascience, 2017"all the ten chapters share –despite the diverse historiographical traditions of the authors and the particularities of each case study - similar historical sensibilities, a high level of historiographical sophistication, and rich and innovative historical sources. This coherence of the volume is the consequence of true teamwork and academic and editorial excellence."- Stefan Pohl Valero, Universidad del Rosario
