Nisse Strinning (1917-2006) is the father of the legendary String shelving and furniture system. Nisse Strinning was married to Kajsa Strinning, also a designer, who together with her husband developed the String system. The shelving was originally designed in 1949 for Bonniers Folkbibliotek (Peoples Library), Bonniers being the biggest book publisher in Scandinavia. Nisse Strinning studied at the KTH Royal Institute of Technology in Stockholm in the 1940s and developed a washing up drying rack called Elfa, which featured plastic coated metal rods. This became the starting point for the String system. In 1952 Nils and Kajsa Strinning founded String Design AB and Swedish Design AB. Together they designed a wide range of plastic objects in the 1960s and 1970s. String can be found in many Swedish homes and is a true icon of Swedish design.
