This typeface was initially released as Neue Haas Grotesk, and was designed in 1957 by Max Miedinger for the Haas’sche Schriftgiesserei (Haas Type Foundry) in Switzerland.
The name was changed to Helvetica (an adaptation of Helvetia, the Latin name for Switzerland) by Walter Cunz when D. Stempel AG, a major stockholder in Haas, reworked the design for Linotype GmbH in Frankfurt, a major stockholder in Stempel. The Mergenthaler Linotype Company in New York, then a major stockholder of Linotype GmbH, adopted the design, and it rapidly became the most popular sanserif in the world, replacing Futura.
Helvetica is designed as a strong central series, with condensed and extended forms and extreme weights adapted and added later, a system which suited Linotype mechanical limitations and marketing philosophy, but which resulted in a family of weights that were not as well coordinated as they might have been.
