Pioneering Swiss modernist Architect Alfred Roth worked in the studio of Le Corbusier and Pierre Jeanneret. His projects include the design for the two houses of the International Exposition in Stuttgart. In 1931 he opened his own atelier and carried out important work in Switzerland, Sweden, the United States, and in the Middle East.

In collaboration with Marcel Breuer he constructed the “Doldertal” houses in Zürich. He also served as a guest professor at the Universities of Harvard and Saint Louis as well as at the Polytechnic High School in Zürich. Roth also published several books on architecture, focusing on his liaisons with the most famous exponents of modern architecture, such as Le Corbusier, Loos, Hoffmann, Perret, Van De Velde, and Piet Mondrian.

The iconic 'AR1' bar trolley was designed by Alfred Roth for Embru in 1932. Today it is hand crafted under license in limited editions by Italian atelier MisuraEmme. The design was highly progressive when conceived and today retains its elegance, practicality and modernity; with a sliding table top, built-in ice box, perforated aluminium bottle container and a small wooden cabinet with doors, it's a near perfect little bar on wheels.
