Simon Gate was a Swedish glass artist, painter, and designer. After studying at the Academy of Arts, he started working at the Orrefors glass factory. Together with the glass artist Edward Hald, he contributed to the glass factory's first international success. From 1916, Simon Gate produced the so-called ’graal’ glass, which master blower Knut Bergqvist further developed from cameo glass. Today, the graal glass pieces from Orrefors are among the most sought-after pieces of art glass among Swedish collectors. Together with Knut Bergqvist, he also created the so-called ’slottsglas’ which have received much attention recently. Simon Gate also became famous for his engraving compositions on the glasses, which were decorated with, among other things, processions and dancing women.
