"The Anglepoise lamp, c 1930."

"Page from a brochure promoting the use of the lamp at home. In the early 1930s George Cawardine, a motor car engineer, conceived the idea of balancing a weight against a spring through a linkage which allowed the weight to remain stable in any position. He joined forces with Herbert Terry & Son of Redditch, who specialised in in making springs. The idea was patented and subsequently the name 'Anglepoise' was coined. The first lamps, made in 1933, were an instant success."
