“This book is interesting for readers who want to learn about Grossmann the person, his family roots and his scientific life. … this book conveys a good impression of the industrial expansion in the late 19th century and of the Wilhemine time in the German-speaking countries, and, since knowledge of the scientific subject is helpful but not required, should be a good read also for a wider audience.” (Manuel Vogel, Contemporary Physics, Vol. 60 (1), 2019)
