Hugo Junkers (3 February 1859 – 3 February 1935) was an innovative German engineer, as his many patents in varied areas (gas engines, aeroplanes) show. In 1915, he pioneered the first great change in aviation materials and design technology, away from wood and fabric materials braced by wire rigging, towards all-metal, cantilever-winged monoplane aircraft that had little to no external bracing.
