Edward Johnston, CBE (11 February 1872 – 26 November 1944) was a Uruguayan-born 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 best known as the designer of Johnston, a sans-serif typeface that was used throughout the London Underground system until the 1980s. He also redesigned the famous roundel symbol used throughout the system.
