History of transport in the Isle of Man

Richard "Jock" Kinneir (11 February 1917 – 23 August 1994) was a British typographer and graphic designer who, with colleague Margaret Calvert, designed many of the road signs used throughout the United Kingdom, Crown Dependencies, and British overseas territories. Their system has become a model for modern road signage.

Margaret Vivienne Calvert OBE RDI (born 1936) 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 font used on road signs, the Rail Alphabet font 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.

David Rogerson Mellor CBE FCSD RDI (5 October 1930 – 7 May 2009) was an English designer, manufacturer, craftsman and retailer.
