Trained as illustrator and textile designer, Franck was employed in 1945 by the legendary Finnish glass works iittala but became design director of the large porcelain factory Arabia already in 1946. In 1950 he became design director of glass works Nuutajärvi. Franck revolutionised the dinnerware in Scandinavia with his radical but simple and utilitarian glass, plates and bowls which all could be mixed and matched.

The Kilta (later Teema) series for Arabia was fired in the same kiln as the companies wash basins and toilet bowls. Until today, more than 25 million pieces have been sold. Franck also produced beautiful art glass at iittala and Nuutajärvi, today highly valued by collectors around the world.
