In December 1941 Levi received an informal job offer from an Italian officer to work as a chemist, under a clandestine identity, at an asbestos mine in San Vittore. The project was to extract nickel from the mine spoil, a challenge he accepted with pleasure. Levi later understood that, if successful, he would be aiding the German war effort, which was suffering nickel shortages in the production of armaments. The job required Levi to work under a false name with false papers. Three months later, in March 1942, his father died. Levi left the mine in June to work in Milan. Recruited through a fellow student at Turin University, working for the Swiss firm of A Wander Ltd on a project to extract an anti-diabetic from vegetable matter, he took the job in a Swiss company to escape the race laws. It soon became clear that the project had no chance of succeeding, but it was in no one's interest to say so.
