A principal aim of this first biography of Robert Le Rossignol, engineer of the Haber process, is to bring new evidence to the attention of the scientific community allowing a re-assessment of the origins of the 'Haber' process. However, the scope of the book is much wider and goes beyond the discovery of 'fixation' to account for a life distinct from Haber, one full of remarkable science, cruel circumstance, personal tragedy and amazing benevolence, the latter made possible by Haber’s generous financial arrangement with Le Rossignol regarding his royalties from the BASF.
