Foundation & Development: In 1919 Max Ramstein, his wife Emilia and Louis Iberg took over the optical shop on Eisengasse in Basel under the name Ramstein Iberg & Co.
Emilia took over the commercial management.
Move to the Market Square: In 1940 the flourishing business moved into a prominent storefront directly beside Basel’s Town Hall at Marktplatz 11. Art-historical significance: Around 1949/1950 the business commissioned the then-young and little-known artist Jean Tinguely as window dresser. Tinguely’s imaginative and kinetic window decorations in wire for Ramstein Iberg were considered pioneering and already hinted at his later world-renowned signature as an object artist. These historic window arrangements were also part of the exhibition [Fresh Window at Museum Tinguely].
Current status: The renowned specialty shop still exists today at Marktplatz in Basel under the modern name Ramstein Optik.
