Margaret Calvert

Margaret Vivienne Calvert is a British typographer and graphic designer who, with colleague Jock Kinneir, designed many of the road signs used throughout the United Kingdom, Crown Dependencies, and British Overseas Territories, as well as the Transport typeface used on road signs, the Rail Alphabet typeface used on the British railway system, and an early version of the signs used in airports. The typeface developed by Kinneir and Calvert was further developed into New Transport and used for the single domain GOV.UK website in the United Kingdom.
