Making Ammonia

Dr. Benjamin Johnson completed his Ph.D. in physics in 2010 at the Technische Universität Berlin with a thesis on thin layer solar cells investigated with X-ray spectroscopic methods. His later research focused on catalytic materials for alternative fuels. In 2015, Dr. Johnson began research in the field of science history, investigating progress in science and technological innovation. His work has resulted in a detailed portrayal of Fritz Haber’s discovery of ammonia synthesis in the first decade of the twentieth century. Continuing in the direction of scientific and technological development, Dr. Johnson is now applying these ideas to prospective technologies for the current energy transition. His approach combines the natural sciences with history and science communication to provide a roadmap for science-based governance incorporating voices from civil society

“Making Ammonia is a well-written and engaging book that makes a significant contribution to our understanding of the history of the ammonia synthesis. Johnson’s book is particularly strong in its exploration of the social and political context in which Fritz Haber worked and provides us with a vivid account of how cultural, technical, and social factors concur in producing a scientific discovery.” (Massimiliano Badino, The British Journal for the History of Science, Vol. 57 (2), June, 2024)
