Monotype
In the early part of the 20th century the Monotype Corporation developed a series of typesetting machines that used hot metal to cast individual letters. It was floated on the London Stock Exchange in 1936.
To support their typesetting machines they developed a large library of typefaces, most of which are familiar today and are available in digital form.
In 1998 Agfa-Compugraphic acquired Monotype to form Agfa-Monotype Corporation, which was subsequently incorporated into Monotype Imaging Inc.
