Margaret Calvert, typographer and graphic designer, is probably best known for her work with her former tutor and design partner, Jock Kinneir, on the design of Britain's radical new road signing system (including the lettering 'Transport'). Designed in the period between 1959 and 1963, it is still in use today, despite minor modifications. For details see New Transport website.
Her 'Woman at Work' self portrait, based on her Road works sign, was exhibited in the 2008 Royal Academy Summer Exhibition. She is a Senior Fellow of the Royal College of Art, a member of AGI, and a Royal Designer for Industry.
