Edward Johnston,
CBE (11 February 1872 – 26 November 1944) was a Uruguayan and
British craftsman who is regarded, with
Rudolf Koch, as the father of modern
calligraphy, in the particular form of the broad edged pen as a writing tool. He is most famous for designing the
sans-serif Johnston typeface that was used throughout the
London Underground system until it was re-designed in the 1980s. He also redesigned the famous
roundel symbol used throughout the system.
