Velcro
De Mestral gave the name "Velcro", a portmanteau of the French words "velour" ("velvet") and "crochet" ("hook"), to his invention as well as his company, which continues to manufacture and market the fastening system.
Acrow prop
The props were invented by Swiss-born William de Vigier, who came to London in 1935. At first traditionalism amongst builders preferred the established timber props, cut to fit for each job. The break for Vigier's adjustable props came when they were adopted by a few large builders, including Sir Robert McAlpine. By 1939, over 40,000 Acrow props were in use.
