The architect Erik Lundberg (1895-1969) is one of the most influential church restoration architects in Sweden of all time, and as the Danish artist Asger Jorn described him “…the only real architectural historian we at all have…”. Lundberg’s ten volume magnum opus Arkitekturens Formspråk (The language of form in architecture 1945-60) is to this day, a unique source to theories about the experience of architecture for old as well as new generations of architects. But Lundberg’s role as a designer has remained largely unknown. For the majority of the churches that he worked on in Sweden, Lundberg also designed light fittings with a unique expression which broke with the ideal aesthetics of functionalism. With the help of the Lundberg family, interviews with former colleagues – and with previously largely unpublished photographs, sketches and drawings – this book for the first time aims to present Erik Lundberg in a perspicuous way to a wider design interested crowd and give him a place in the history of Swedish design.
