Louis Poulsen
Louis Poulsen is a Danish lighting manufacturer with a history extending back to the late 19th century. The company became one of the most influential names in Scandinavian lighting during the 20th century, particularly through its collaborations with leading Danish architects and designers. Its approach has traditionally centred on shaping and controlling illumination through carefully considered forms rather than treating the lamp simply as a decorative object.
Biography
The company traces its origins to Copenhagen in 1874, when Ludvig R. Poulsen established a business supplying tools and electrical equipment. His nephew Louis Poulsen joined the company in the 1890s and later assumed ownership, giving the business the name by which it is known today.
A decisive development came through the company's collaboration with Danish designer and architect Poul Henningsen. Beginning in the 1920s, Henningsen investigated how layered shades could distribute illumination while reducing glare. This work resulted in his influential multi-shade system and established principles that became fundamental to Louis Poulsen's identity.
Henningsen's PH lamps brought the company international attention following their presentation at the 1925 International Exhibition of Modern Decorative and Industrial Arts in Paris. The collaboration continued for decades and produced numerous designs, including the PH series, the PH Artichoke and the PH 5, all based on Henningsen's extensive study of reflection, glare and the relationship between illumination and its surroundings.
During the post-war period, Louis Poulsen expanded its collaborations with prominent Danish designers and architects. Arne Jacobsen created several lamps in connection with his interior projects, most notably the AJ series developed for the SAS Royal Hotel in Copenhagen. Vilhelm Lauritzen, another important collaborator, designed lighting for projects including Radiohuset in Copenhagen.
The company later worked with figures including Verner Panton, whose sculptural Panthella lamp was introduced in 1971. These collaborations broadened Louis Poulsen's catalogue while maintaining an emphasis on the relationship between form, function and the distribution of illumination.
