20th-century engravers

Maurits Cornelis Escher (Dutch pronunciation: [ˈmʌurɪt͡s kɔrˈneːlɪs ˈɛʃər]; 17 June 1898 – 27 March 1972) was a Dutch graphic artist who made woodcuts, lithographs, and mezzotints, many of which were inspired by mathematics.
Despite wide popular interest, for most of his life Escher was neglected in the art world, even in his native Netherlands. He was 70 before a retrospective exhibition was held. In the late twentieth century, he became more widely appreciated, and in the twenty-first century he has been celebrated in exhibitions around the world.
His work features mathematical objects and operations including impossible objects, explorations of infinity, reflection, symmetry, perspective, truncated and stellated polyhedra, hyperbolic geometry, and tessellations. Although Escher believed he had no mathematical ability, he interacted with the mathematicians George Pólya, Roger Penrose, and Donald Coxeter, and the crystallographer Friedrich Haag, and conducted his own research into tessellation.
Early in his career, he drew inspiration from nature, making studies of insects, landscapes, and plants such as lichens, all of which he used as details in his artworks. He traveled in Italy and Spain, sketching buildings, townscapes, architecture and the tilings of the Alhambra and the Mezquita of Cordoba, and became steadily more interested in their mathematical structure.
Escher's art became well known among scientists and mathematicians, and in popular culture, especially after it was featured by Martin Gardner in his April 1966 Mathematical Games column in Scientific American. Apart from being used in a variety of technical papers, his work has appeared on the covers of many books and albums. He was one of the major inspirations for Douglas Hofstadter's Pulitzer Prize-winning 1979 book Gödel, Escher, Bach.

Warwick Hutton (17 July 1939 – 28 September 1994) was a British painter, glass engraver, illustrator, and children's author.
He is most widely known for elegant pen and ink and watercolor illustrations for children’s books. His subjects were Biblical, folk, and mythological stories which Hutton retold, such as Noah and the Great Flood, The Nose Tree, and Theseus and the Minotaur. He also worked with texts by Hans Christian Andersen (The Tinderbox) and with retellings of traditional stories by author Susan Cooper (The Silver Cow, The Selkie Girl, Tam Lin).
The Nose Tree and Jonah and the Big Fish were chosen for the New York Times’s annual list of best-illustrated children's books. Jonah and the Great Fish was also the recipient of the 1984 Boston Globe-Horn Book Award for Best Picture Book.
Hutton died of cancer on 28 September 1994 in Cambridge, England.
His parents were immigrants from New Zealand; his father was the artist and glass engraver John Hutton and his mother was also a modern artist, called Helen Blair.

Before that, he was Assistant Engraver. He designed both sides of the Susan B. Anthony dollar, both sides of the Eisenhower Dollar (with the exception of the Bicentennial issues of 1975–1976), the Lincoln Memorial reverse of the cent (minted from 1959 to 2008), and the reverse of the Kennedy half dollar.

Gascón also illustrated hundreds of books and periodicals, originating the drawing style known as helenismo picassiano.

José Guadalupe Posada Aguilar (2 February 1852 – 20 January 1913) was a Mexican political lithographer who used relief printing to produce popular illustrations. His work has influenced numerous Latin American artists and cartoonists because of its satirical acuteness and social engagement. He used skulls, calaveras, and bones to convey political and cultural critiques.
Among his most enduring works is La Calavera Catrina.
