Simon Terry, the great-great grandson of Herbert and innovation director at Anglepoise Ltd, is the fifth generation of the family at the company.

Designed by the automotive engineer George Carwardine, the ANGLEPOISE lamp is based on the ability of a new type of spring invented by Carwardine in 1932 to remain in position after being moved in every conceivable direction. Efficient and energy-saving, the Anglepoise has remained in production ever since. Having finalised his design, Carwardine decided to license it to Herbert Terry & Sons, a manufacturer based at Redditch in Worcestershire which supplied springs to his factory. The company was then run by Charles Terry, the eldest son of its founder Herbert. He personally signed the licensing agreement for Carwardine's lamp.
