Ferdinand Theinhardt Akzidenz Grotesk 1898
A little bit of font love this morning from Akzidenz Grotesk. Those numbers 2 + 7 are perfect; that lowercase 'a'. And while I've always loved Helvetica's "R", I'm digging this one.
Berlin-based foundry from the 19th century, whose typefaces included Aldeutsch (aka Psalterium, or as Mainzer Gotisch, 1851). Ferdinand Theinhardt (b. Halle, 1820, d. Berlin, 1909) ran it.
Around 1880, he published four weights of a Royal Grotesk (in 4 styles) for the Prussian Academy of Sciences in Berlin (see, e.g., here or here; here is a sample of his 1895 Breite Grotesk). Akzidenz Grotesk is often given the 1898 date. In 1908, H. Berthold AG took over the Theinhardtsche Giesserei. In 1918, H. Berthold sold that Royal Grotesk as Akzidenz Grotesk. —http://luc.devroye.org/fonts-46521.html
