Erling Christoffersen (1932–2015) was a Norwegian jeweler who founded the Plustinn Norway applied arts centre in Fredrikstad in 1958.
He began his career at the National College of Art and Design in Oslo. 1 At the age of 17, he began working as an apprentice at the renowned Norwegian company J. Tostrup.
Together with his wife, Anna Greta Eker, he ran a jewellery workshop in the 1960s, both in Norway and abroad.
Christoffersen and his wife continued to work at Plus until the centre closed in the mid-1970s.
In addition to jewellery, Christoffersen’s workshop also brought together artists and craftsmen of various disciplines: silversmiths, ceramicists, weavers, glassblowers, carpenters, furniture designers and others.
