printing of Greek (the Didot family were among the first to set up a printing press in the newly independent country). It also is often seen in mathematics, as the open-source standard mathematical typesetting programmes TeX and LaTeX use the Computer Modern family as default. The system's creator, Donald Knuth, deliberately created the system with the intention of producing an effect inspired by the "classic style" of nineteenth-century scientific printing with a family based on an American Monotype Company Modern face. Many newspapers were founded in the nineteenth century, and many newspaper typefaces have remained rooted in nineteenth-century models of type. Linotype's popular Legibility Group of the 1930s, for many years the model for most newspaper printing worldwide, remained based on this model but toughened-up to increase clarity. American Type Founders' Bodoni typeface, introduced around 1907-1911, became hugely popular for news headlines. Writing in 2017, digital font designer Tobias Frere-Jones wrote that he had kept his font design for The Wall Street Journal based on the nineteenth-century model because it "had to feel like the news." Among popular faces in modern use, the typeface family Century is inspired by later American Didone designs, although compared to many in the Didone genre it has quite a low level of stroke contrast, suitably for its purpose of high legibility in body text. Typefaces of the period have often been revived since for cold type and digital composition, while modern typefaces along the same lines include Filosofia and the open-source Computer Modern. Some later Didone families have focused on subgenres of the period, such as Surveyor, inspired by labels on maps. Fat face typefaces remained popular for display use in the mid-twentieth century with new designs such as Monotype's Falstaff and Morris Fuller Benton's Ultra Bodoni; Matthew Carter's Elephant is a more recent version. Usage In print, Didone fonts are often used on high-gloss magazine paper for magazines such as Harper's Bazaar, on which the paper retains the detail of their high contrast well, and for whose image a crisp, 'European' design of type may be considered appropriate. They are used more often for general-purpose body text, such as book printing, in Europe. The effective use of digital Didone typefaces poses unique challenges. While they can look very elegant due to their regular, rational design and fine strokes, a known effect on readers is 'dazzle', where the thick verticals draw the reader's attention
