A ‘founding father’ of zeolite science and its applications, Richard Barrer was also known for his research in the gas permeability of membranes. Throughout his career he wrote over 400 papers, 3 monographs and held 21 patents. His contributions to his field saw him give his name to the zeolite ‘Barrerite’ and Barrer, a unit of gas permeability still used today. He primarily resided in the UK, and taught in Cambridge, London and Aberdeen. His legacy continues through the Barrer Award, recognising work in the field of porous inorganic materials.
