Margaret Vivienne Calvert[1]OBERDI (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.[2]
Born in South Africa, Calvert moved to England in 1950, where she studied at St Paul's Girls' School and the Chelsea College of Art. Kinneir, her tutor there, asked her to help him design the signs for Gatwick Airport. They chose the black on yellow scheme for the signs after researching the most effective combination.[3] They also designed luggage labels for P & O Lines in 1957.[4][5]
In 1957, Kinneir was appointed head of British signs for Britain's roads. He then hired Calvert[6] to redesign the road sign system and she came up with simple, easy-to-understand pictograms, including the signs for 'men at work' (a man digging), 'farm animals' (based on a cow named Patience that lived on a farm near to where she grew up), and 'schoolchildren nearby' (a girl leading a boy by the hand, which she said were actually modelled after herself), using the European protocol of triangular signs for warnings and circles for mandatory restrictions.[7] The Worboys Committee was formed by the British government in July 1963 to review signage on all British roads.
In addition to her road signs, Calvert has designed commercial fonts for Monotype, including the eponymous Calvert font, a slab serif design which she created in 1980. It originated in a 1970s proposal to the French new town of Saint Quentin-en-Yvelines for a new font to provide a visual identity for the town. However, the slab-serif typeface and three-dimensional letter shapes were rejected.[5] The font was later adopted by the Tyne and Wear Metro system as well as north-east England bus and ferry services in the 1980s.[8]
In 2020 a new version of the font used in the UK rail system was introduced, Rail Alphabet 2. It was designed in collaboration with Henrik Kubel.[9]
Calvert taught at the Royal College of Art for almost 40 years and was head of graphics from 1987 to 1991.[5]
She appeared on the fourteenth season of the famous motoring show, Top Gear on 3 January 2010. James May interviewed her in a 2009 Vauxhall Insignia VXR, talking about the design process of the UK road signs.[11]
A retrospective exhibition of her work, Margaret Calvert: Woman at Work,[9] was held from 21 October 2020 till 10 January 2021 at the Design Museum in London.[5]
