Gill Sans

Gill Sans is a humanist sans-serif typeface designed by Eric Gill and released by the British branch of Monotype in 1928. It is based on Edward Johnston's 1916 "Underground Alphabet", the corporate typeface of London Underground.

As a young artist, Gill had assisted Johnston in its early development stages. In 1926, Douglas Cleverdon, a young printer-publisher, opened a bookshop in Bristol, and Gill painted a fascia for the shop for him using sans-serif capitals. In addition, Gill sketched an alphabet for Cleverdon as a guide for him to use for future notices and announcements. By this time, Gill had become a prominent stonemason, artist and creator of lettering in his own right, and had begun to work on creating typeface designs.

Gill was commissioned to develop his alphabet into a full type family by his friend Stanley Morison, an influential Monotype executive and historian of printing. Morison hoped that it could be Monotype's competitor to a wave of German sans-serif families in a new "geometric" style, which included Erbar, Futura and Kabel, all of which had been launched to considerable attention in Germany during the late 1920s. Gill Sans was initially released as a set of titling capitals that was quickly followed by a lower-case. Gill's aim was to blend the influences of Johnston, classic serif typefaces and Roman inscriptions to create a design that looked both cleanly modern and classical at the same time. Because Gill Sans was designed before the practice of setting documents entirely in sans-serif text became common, its standard weight is noticeably bolder than most modern body text fonts.

Gill Sans was an immediate success; a year after its release, the London and North Eastern Railway (LNER) chose the typeface for all its posters, timetables and publicity material. British Railways chose Gill Sans as the basis for its standard lettering when the Big Four railway companies were nationalised in 1948. Gill Sans also soon became used on the deliberately simple modernist covers of Penguin Books, and was sold up to very large font sizes, which were often used in British posters and notices of the period. Gill Sans was one of the dominant typefaces in British printing in the years after its release, and remains extremely popular. It has been described as "the British Helvetica" because of its lasting popularity in British design. Gill Sans has influenced many other typefaces and helped to define a genre of sans-serif, known as the humanist style.

Monotype rapidly expanded the original regular or medium weight into a large family of styles, which it continues to sell. A basic set is included with some Microsoft software and macOS fonts.
