Edward Johnston

Eric Johnston, born in 1872 was a British-Uruguayan craftsman, now considered to be the father of modern calligraphy and typography. He was a major influence to Eric Gill, the creator of Gill Sans, and he's most famous for creating the sans-serif Johnston typefaces that was used on the London Underground system until it was redesigned in the 1980's, as well as on the massively iconic roundel symbol used throughout the systems. In 1921, students of Eric Johnston formed the Society of Scribes and Illuminators, probably the world's foremost calligraphy society.

The typeface Johnston (or Johnston Sans) is a humanist sans-serif typeface. Johnston's former student Eric Gill also helped with the development of this typeface and it later influenced Gill Sans.
