This is a stand-alone chapter in Levi’s autobiographical mosaic of fact and fiction as told through the chemical elements he has worked with. ‘Iron’ describes his attempt to identify an unknown chemical substance when he was a student in Fascist Italy, and moves from there to a poignant study of a fellow student who became a resistance fighter, and whose ‘iron’ moral strength inspired Levi. The Periodic Table was chosen by the Royal Institution in 2006 as ‘the best science book ever’.
