The Worboys Committee was formed by the British government in July 1963 to review signage on all British roads. This was in response to two articles published in 1961 by graphic designer Herbert Spencer, illustrating the shortcomings of non-motorway British road signs. The committee was chaired by Sir Walter Worboys of ICI. T. G. Usborne of the Ministry of Transport had charge of proceedings, and Jock Kinneir and his assistant (and later business partner) Margaret Calvert were commissioned as designers.
