'''AMS Euler''' is an [[Italic type#Upright italics|upright cursive]] [[typeface]], commissioned by the [[American Mathematical Society]] (AMS) and designed and created by [[Hermann Zapf]] with the assistance of [[Donald Knuth]] and his Stanford graduate students. It tries to emulate a mathematician's style of handwriting mathematical entities on a blackboard, which is upright rather than [[italic type|italic]].<ref>{{cite journal |last1=Knuth |first1=Donald E. |last2=Zapf |first2=Hermann |title=AMS Euler — a new typeface for mathematics |journal=Scholarly Publishing |volume=20 |issue=3 |date=April 1989 |pages=131–157 |publisher=University of Toronto Press |location=Toronto}}</ref><ref>{{cite book |last=Zapf |first=Hermann |author-link=Hermann Zapf |title=Hermann Zapf and his design philosophy — selected articles and lectures on calligraphy and contemporary developments in type design, with illustrations and bibliographical notes, and a complete list of his typefaces |publisher=Society of Typographic Arts |location=Chicago |year=1987}}</ref> It blends very well with other typefaces made by [[Hermann Zapf]], such as [[Palatino]], [[Aldus (typeface)|Aldus]] and [[Melior (typeface)|Melior]], but very badly with the default [[TeX]] font [[Computer Modern]].{{Citation needed|date=August 2023|reason=Unless based on facts, like, e.g., font metrics, or citation from its authors/other specialists, this is a subjective statement}} All the alphabets were implemented with the computer-assisted design system [[Metafont]] developed by Knuth. Zapf designed and drew the Euler alphabets in 1980–81 and provided critique and advice of digital proofs in 1983 and later. The typeface family is copyright by American Mathematical Society, 1983. Euler [[Metafont]] development was done by Stanford computer science and/or digital typography students; first [[Scott Kim]], then [[Carol Twombly]] and Daniel Mills, and finally [[David Siegel (entrepreneur)|David Siegel]], all assisted by John Hobby. Siegel finished the Metafont Euler digitization project as his M.S. thesis in 1985.

The AMS Euler typeface is named after [[Leonhard Euler]].<ref name=":0" />

First implemented in [[METAFONT]], AMS Euler was first used in the book ''[[Concrete Mathematics]]'', which was co-authored by Knuth and dedicated to Euler.<ref name=":0">{{cite journal |last=Knuth |first=Donald E. |title=Typesetting Concrete Mathematics |journal=[[TUGboat]] |volume=10 |issue=1 |date=April 1989 |pages=31–6 |publisher=TeX Users Group |location=Providence, RI |url=http://www.tug.org/TUGboat/tb10-1/tb23knut.pdf |access-date=2012-02-11}}<br />{{cite journal |editor-last=Beeton |editor-first=Barbara |title=Erratum: Typesetting Concrete Mathematics, TUGboat Vol. 10, No. 1 |journal=TUGboat |volume=10 |issue=3 |date=November 1989 |page=342 |publisher=TeX Users Group |location=Providence, RI |url=http://www.tug.org/TUGboat/tb10-3/tb25hara-latin.pdf |access-date=2012-02-11}}</ref> This volume also saw the debut of Knuth's [[Concrete Roman]] font, designed to complement AMS Euler. The Euler Metafont format fonts were converted to [[PostScript Type 1]] font format by the efforts of several people, including [[Berthold K.P. Horn|Berthold Horn]] at Y&Y, Barry Smith at Bluesky Research, and Henry Pinkham and Ian Morrison at Projective Solutions. It is now also available in [[TrueType]] format.
