Tex may refer to:
Tex is often used as a nickname for someone from the U.S. state of Texas.
TeX (/ˈtɛx/ or /ˈtɛk/, see below) is a typesetting system designed and mostly written by Donald Knuth and released in 1978.
Together with the Metafont language for font description and the Computer Modern family of typefaces, TeX was designed with two main goals in mind: to allow anybody to produce high-quality books using a reasonably minimal amount of effort, and to provide a system that would give exactly the same results on all computers, at any point in time.
TeX is a popular means by which to typeset complex mathematical formulae; it has been noted as one of the most sophisticated digital typographical systems in the world. TeX is popular in academia, especially in mathematics, computer science, economics, engineering, physics, statistics, and quantitative psychology. It has largely displaced Unix troff, the other favored formatter, in many Unix installations, which use both for different purposes. It is also used for many other typesetting tasks, especially in the form of LaTeX, ConTeXt, and other template packages.
Tex Willer is the main fictional character of the Italian comics series Tex, created by writer Gian Luigi Bonelli and illustrator Aurelio Galleppini, and first published in Italy on 30 September 1948. It is among the most popular characters of Italian comics, with translations to numerous languages all around the world. The fan base in Brazil is especially large, but it is very popular also in Finland, Norway, Turkey, Croatia, France, Tamil Nadu, Serbia and Spain.
The Tex Willer series is an Italian-made interpretation of the American Old West, inspired by the classical characters and stories of old American Western movies.
Tex is depicted as a tough guy with a strong personal sense of justice, who becomes a ranger (even if living in Arizona) and defends Native Americans and any other honest character from exaction and greed of bandits, unscrupulous merchants and corrupt politician and tycoons.
Native Americans are portrayed in a complex way, emphasizing positive and negative aspects of their culture. The same can be said of the American authorities, like the U.S. Army, the politicians, the business-men, the sheriffs or the Bureau of Indian Affairs. Tex had a son, named Kit Willer (who would become a ranger too), with a Native American woman, named Lilyth, the daughter of a Navajo Chief (she would later die of smallpox). Later, Tex himself went on to become the Chief of the Navajo tribe.
