 The H. Berthold foundry's most celebrated family of typefaces is arguably Akzidenz-Grotesk (released 1898), an early sans-serif which prefigured by half a century the release of enormously popular neo-grotesque faces such as Helvetica.In 1950, type designer Günter Gerhard Lange embarked upon a long affiliation with the company, for which he designed various original typefaces, including Concorde and Imago, and oversaw the foundry's revivals of classic faces such as Garamond, Caslon, Baskerville, and Bodoni.As a typefounder, Berthold had no background in producing cold type machinery until the introduction of the Diatype in 1958.
