Mark Simonson · Mark Simonson · 2009

A free, open-source fixed-width family for code, descended from Mark Simonson's own 1990s bitmap font Anonymous.
About
Anonymous Pro is a four-style monospaced family aimed squarely at programming use, with an international Unicode character set covering Western and Central European Latin, Greek and Cyrillic. It traces back to Anonymous, Simonson's TrueType version of a mid-90s Macintosh bitmap font by Susan Lesch and David Lamkins. It ships in two versions, with and without embedded bitmaps for small sizes, and is released under the Open Font License.
Classification
A fixed-width family built for code, so it sits squarely in mono rather than any text or display category.
