Designed in 1955 by Howard G. Kettler for the IBM bar typewriter and later adapted for the Selectric typewriter, Courier? has truly stood the test of time. Installed on nearly every computer in the world, Courier? is also one of the most used typefaces in history. The 12 pitch mono Kettler type family pays tribute to the simplicity of Howard Kettler¹s monospaced classic by revisiting the smooth letter fit and efficiency of form.
