took up its work on DIN 1451 a few years later. The DIN Committee of Typefaces was headed by the Siemens engineer, Ludwig Goller (1884–1964), who also led the central standardization office at Siemens & Halske in Berlin, between 1920 and 1945. The design included not only the DIN , but also a DIN ('medium[-width] face' – now very popular). A DIN ('extended face') design was also included, but it has never been widely used. In order to enable quick and easy reproduction, all drawings were originally based on a coarse grid and could be executed with compass and rulers. The ('standards sheet') DIN 1451, ('typefaces') was released preliminarily in 1931; then, with some minor changes in 1936, it was released as an official standard. In 1938, Temporary Order No. 20 required DIN 1451 to be used on the new German (motorway) system. Due to this and similar regulations, DIN 1451 still dominates German public lettering today. In 1923, Stempel was the first type foundry to produce printing type according to a DIN Standard. The design follows DIN 16, an earlier standard for oblique lettering on technical drawings, which had been released in 1919. In 1929, the Berthold Type Foundry released a similar typeface. DIN 16 had also been made available as lettering templates engraved in celluloid material for drafting use by the Filler and Fiebig company in Berlin. Within the scope of public and technical lettering, the use of the DIN 1451 typefaces spread rapidly once they were adopted. They were released as celluloid lettering stencils for smaller applications, as larger metal stencils for application to machinery, vehicles and airplanes, and as cast metal lettering for street and building signage; nevertheless, printing type conforming to DIN 1451 have never been produced. During World War II, DIN 1451 was also adopted in the Protectorate of Bohemia and Moravia. The 1943 version of DIN 1451 added a set of Cyrillic characters, although their design did not match the weight and proportions of DIN . Sans-serif lettering and typefaces styled around geometric shapes, along with Art Deco in general, was very popular in the 1920s and 1930s. At the Bauhaus, the use of coarse grids for designing typefaces was advocated by Herbert Bayer and Joost Schmidt during the Dessau period. Although of a similar design, the DIN typefaces did not incorporate the elegance of this stylistic trend. Inspired by the DIN standard,
