Johnston

Johnston (or Johnston Sans) is a humanist sans-serif typeface designed by and named after Edward Johnston. It is well known for its use by Transport for London.

Johnston's former student Eric Gill also worked on the development of the typeface, which was later to influence his own Gill Sans typeface, produced 1928–32.

Features
Features of the font are the perfect circle of the letter O and the use of a diagonal square dot above minuscule letters i and j and for the full stop. Commas, apostrophes and other punctuation marks are also based on the diagonal square dot. The capitals of the typeface are based on Roman square capitals, and the lower-case on the humanistic minuscule, the handwriting in use in Italy in the fifteenth century. In this, it marked a break with the kinds of sans serif previously used, sometimes known as grotesque, which tended to have squarer shapes.

History
The typeface was commissioned in 1913 by Frank Pick, Commercial Manager of the Underground Electric Railways Company of London (also known as 'The Underground Group'), as part of his plan to strengthen the company's corporate identity, and introduced in 1916. Pick specified to Johnston that he wanted a typeface that would ensure that the Underground Group's posters would not be mistaken for advertisements; it should have "the bold simplicity of the authentic lettering of the finest periods" and belong "unmistakably to the twentieth century". In 1933, The Underground Group was absorbed by the London Passenger Transport Board and the typeface was adopted as part of the London Transport brand.

The font family was originally called Underground. It became known as Johnston's Railway Type, and later simply Johnston. It comes with two weights, heavy and ordinary. Heavy does not contain lower-case letters.

New Johnston
The Johnston typeface was redesigned in 1979 by Eiichi Kono at Banks & Miles to produce New Johnston; this variant of the original typeface is currently used by London Underground in their signage. The new typeface is slightly heavier or bolder than the original, and larger 'x' height relative to the ascenders and descenders. Punctuation marks are now stylised to match the diamond tittle, differing from Johnston's original design. The new family comes with Bold, Medium, Light weights. The new typeface replaced the old typeface.

In 2002 the typeface was digitized on behalf of Transport for London by Agfa Monotype Corporation, with the addition of two further weights, Book and Book Bold, and as well as corresponding italic variants. The revised font family – not commercially available – is known as 'New Johnston TfL'.

A further change occurred in 2008 when Transport for London removed the serif from the numeral '1' and also altered the '4', in both cases reverting these to their original appearance.

Johnston Delf Smith
The original font was developed in the 1920s by Percy Delf Smith (another former pupil of Edward Johnston). It was commissioned by Frank Pick of London Underground as a petit-serif variation of the organisation's standard sans-serif Johnston face. The typeface was originally used for the headquarters building at 55 Broadway, SW1. It can still be seen on some signs at Sudbury Town and Arnos Grove on the Piccadilly line.

In early 2007, an electronic version of the typeface was developed under the name Johnston Delf Smith, specifically for use on historic signs.

ITC Johnston
International Typeface Corporation released a variant in 1999 called ITC Johnston, produced by British type designers Richard Dawson and Dave Farey. It originally included three font weights like New Johnston. However, it does not include the hooked 1 and uses side-pointed 4.

In November 2002, the typeface was rereleased in OpenType format, which also expanded the font family to include italic fonts in all weights. Character set was expanded to support ISO Adobe 2 character set. OpenType features include alternates, case forms, small caps (romans only), old style figure. Separate small caps (romans only) and old style figure faces were also released for each weight in TrueType and PostScript formats, for a total of fifteen typefaces.

ITC Johnston Pro
Released in March 2009, this version includes support of Adobe CE character set.

Johnston Underground
In 1997, London Transport Museum licensed the original Johnston typeface exclusively to P22 Type Foundry, available commercially as Johnston Underground. Johnston Underground included Regular, Bold, and Extras weights, with the Extra containing only ornamental symbols.

Underground Pro
P22 later had Paul Hunt add to their version of the Underground typeface to create the Underground Pro (or P22 Underground Pro) family. The full Underground Pro Set contains nineteen Pro OpenType fonts and 58 Basic OpenType fonts, covering extended Latin, Greek, Cyrillic character sets. Weights are expanded to six: Thin, Light, Book, Medium, Demi, Heavy. However, there are no italic styles in P22's designs. Underground, Underground CY, Underground GR support extended Latin, Cyrillic, Greek characters respectively. The Latin sub-family contains medium weight Titling fonts, which feature underscored and/or overscored Latin small letters. Pro fonts include extensive OpenType features, including eleven stylistic sets: Petite Capitals, Dryad Cap Alternates, Humanistic Alternates 1, Humanistic Alternates 2, Geometric Alternates, Round Points, Diamond Points, Alternate Tilde, All Under commas, All cedillas, Alternate Eng.

Usages
Its use has included the Tube map, nameplates and general station signing, as well as much of the printed material issued by the Underground Group and its successors; also by the nationalised British Road Services in the immediate post-war era. It was used primarily in the SMRT.

It was also used for wayfinding signs at the London 2012 Olympic and Paralympic Games, including venues outside London. It is also used in the overlays of the BBC TV show Sherlock. New Johnston is used for signage in the fictional Princeton–Plainsboro Teaching Hospital in the FOX TV show House, although in later seasons the similar font Gill Sans was used, most noticeably on Wilson's Door during Season 8. It is also used in the way finding signage at Westfield London.
