He wrote two other highly praised memoirs, ("Moments of Reprieve", 1978) and ("The Periodic Table", 1975). "Moments of Reprieve" deals with characters he observed during imprisonment. "The Periodic Table" is a collection of short pieces, based in episodes from his life but including two short stories that he wrote while employed in 1941 at the asbestos mine in San Vittore. Each story was related in some way to one of the chemical elements. At London's Royal Institution on 19 October 2006, "The Periodic Table" was voted onto the shortlist for the best science book ever written.
