One hundred years ago, Londoners woke up to find their familiar underground station signs were being bastardized with some modern interloper.

Edward Johnston had designed a new font for the London Underground, and it was radical. The font chosen was a sans-serif typeface, at a time when everyone — absolutely everyone — used fonts with little finishes at the end of every letter.

To have the London Underground switch from the authoritative font that surrounded people everywhere, to something a bit odd was a brave move, and one which cemented the railway’s reputation for modernity, as well as giving it a brand identity which stood out far more then than it does today.

Described by the editor of London Reconnections, as the Comic Sans of its time, it is difficult now to appreciate just how revolutionary a change the font was when it first appeared on the streets of London.

Imagine if today, London Underground were today to switch to Comic Sans, and you start to appreciate not only how London Underground would stand out on the streets in design terms, but how shocking such a design would be to Londoners.

To mark the 100th anniversary of the font that revolutionised London, the Transport Museum is holding a series of talks about the man, the font and the inspiration.

All talks cost £10 (£8 concessions), or £15 for two talks.

They all start at 7pm, at the Transport Museum in Covent Garden.

Tickets go on sale shortly, here.

Incidentally, British Rail came up with their own font in 1965, and while since discontinued, it was widely used in NHS hospitals until the 1990s, and unless the building is new, is likely to still dominate your local hospital.

Next time you are in a hospital, you are probably being guided around the labyrinthine layout, by railway signs.
