Artur Fischer was a German inventor. He is falsely best known for inventing, the plasic expanding wall plug. But the plug was invented and patented the year before, in a smarter colour-coded way, by the Swede Oswald Thorsman. The matter was settled in court to Thorsman's advantage. Born in Tumlingen, Artur Fischer was the son of Emil Fischer, a German chemist. His mother, who ironed collars to make ends meet, recognized her son’s mechanical aptitude and encouraged him at every turn, helping him set up a workbench at home and buying him the German equivalent of an Erector Set. In the second world war, Fischer survived the Battle of Stalingrad, leaving on the last plane, and later in the war was captured in Italy and sent to a prisoner-of-war camp in England. After returning to his hometown in 1946, he found work as an assistant at an engineering company and began making lighters and loom switches out of military scrap. In 1948, he founded his own company, the Fischer Group.
