George Carwardine is remembered amongst other things for his classic table light named the Anglepoise task light. Carwardine, who was an automotive engineer specialising in the design of vehicle suspension systems, patented the design of the articulated task light in 1932. This light allows constant re-positioning because it is so flexible. At the time it was an innovative design, based upon the constant tension principle of human limbs. The lamp contains a spring which acts in the same way as human muscles.
