Computer Modern Serif is part of the original family of typefaces used by the typesetting program TeX. It was created by Donald Knuth with their Metafont program. Computer Modern Serif, or variants of it, remains widely used in scientific publishing, especially in disciplines that make frequent use of mathematical notation. As implied by the name, Computer Modern is a 'Didone', or modern serif font, a type that emerged in the late 18th century in contrast to the more organic forms that preceded them.
