AMS Euler

AMS Euler is an upright cursive typeface, commissioned by the American Mathematical Society (AMS) and designed and created by Hermann Zapf with the assistance of Donald Knuth. It tries to emulate a mathematician's style of handwriting mathematical entities on a blackboard, which is upright rather than italic. It blends very well with other typefaces made by Hermann Zapf, such as Palatino, Aldus and Melior, but very badly with the default TeX font Computer Modern. All the alphabets were executed with the computer-assisted design system Metafont developed by Knuth. Work on the design took place 1980-81 with copyright by American Mathematical Society in 1983.

The AMS Euler typeface is named after Leonhard Euler.

First implemented in METAFONT, AMS Euler was first used in the book Concrete Mathematics, co-authored by Knuth, which was dedicated to Euler. This volume also saw the debut of Knuth's Concrete Roman font, designed to complement AMS Euler. The typeface is now also available in other formats, including PostScript Type 1 and TrueType.

The family consist of seven alphabets: Text, Greek, Fraktur, Text Bold, Greek Bold, Script Bold and Fraktur Bold.
