Norman de BruyneBorn 8 Nov 1904; died 7 Mar 1997 at age 92.Dutch inventor who helped to transform aircraft construction by developing strong new lightweight materials and synthetic glues. In 1928, he joined Ernest Rutherford at his Cavendish Laboratory in atomic research. Subsequently developing an interest in flying, by 1934 he started his own company, Aero Research to research his invention of a new form of synthetic glue. The long-established casein glues used until then in the building of wooden aircraft were seriously affected in hot and humid conditions. His own revolutionary cantilever-wing “Snark”monoplane utilized his new bonding methods. Later, his metal-to-metal bonding of lightweight and very strong aluminium honeycomb aircraft structures were extensively used during WW II.[Born in Chile to Dutch parents. Educated and spent most of his life in England. Late in life emigrated and took American citizenship, but returned to England.] |
