Much more than one of Bohr's faithful lieutenants: Helge Kragh: From quanta to gravitation: the science and life of Christian Møller. Copenhagen: The Royal Danish Academy of Science and Letters, 2023, 492 pp, 250,00 DKK.

Helge Kragh's biography of Christian Møller sheds light on the significant contributions Møller made to twentieth-century physics, despite his relative obscurity in historical writings. Møller's work in quantum mechanics, elementary particle physics, and general relativity is extensively covered in the biography, along with his involvement in scientific organizations such as CERN and the International Committee on General Relativity and Gravitation. The book provides detailed discussions of Møller's work, making it more suitable for readers already familiar with twentieth-century physics. While the biography offers valuable insights into Møller's life and work, some aspects, such as his role as a teacher and his philosophical views on science, could have been further explored. Overall, the book serves as a comprehensive starting point for further research on Møller's pedagogy and the development of the "Copenhagen spirit" in physics and philosophy of quantum mechanics.
