Sigurd Persson from Stockholm was especially famous for his modern serial production designs. He intially was the chief designer of the most progressive jewelry company in Sweden, Atelier Stigbert, but in 1952 started his own studio.   He is another Martinshof contributor who won the prestigeous European Goldsmith of the Year award.
Martinshof was the promotor and distributor of his 'Scäla och Ruta' collection in Holland. This was designed using two simple shapes only, concave eliptical dishes and rectangular diamond shapes, all produced in silver. Unfortunately the general Dutch taste was at that time not ready to embrace the progressive modern Scandinavian style, and sales of this very affordable product were rather poor.
