Its use became a hallmark of the International Typographic Style that emerged from the work of Swiss designers in the 1950s and 1960s, becoming one of the most popular typefaces of the mid-20th century. Helvetica is a neo-grotesque design, one influenced by the famous 19th century (1890s) typeface Akzidenz-Grotesk and other German and Swiss designs. Helvetica, also known by its original name Neue Haas Grotesk, is a widely used sans-serif typeface developed in 1957 by Swiss typeface designer Max Miedinger and Eduard Hoffmann.
