First the factory was located in Basel, in the 1920s they relocated to Münchenstein.
Haas traces its origins back to the printer Jean Exertier who began casting type during the second half of the 16th century, later passing to the Genath family.
Haas purchased the French foundries Deberny & Peignot in 1972, and Fonderie Olive in 1978.
With Linotype’s acquisition of the D. Stempel AG in 1985, they became the majority shareholder.
In 1989, Linotype shut down the Haas Foundry, retaining the rights to the typefaces, and transferring metal typefounding operations to Walter Fruttiger AG.
