Bent Gantzel-Boysen
Bent Gantzel-Boysen (1930–2008) was a Danish designer with a background in electromechanics and engineering. He joined Louis Poulsen in 1956 and became head of the company’s design team during the 1970s.
For Louis Poulsen, he designed a number of important lighting models, including the LamPetit table lamp, a design that is often mistakenly attributed to Verner Panton. He is also associated with the IT series and with later additions to the PH family, including the PH 80 table and floor lamps.
In the late 1970s, Gantzel-Boysen started his own company and went on to design lamps for IKEA for about ten years. Among his best-known IKEA designs are the DUETT pendant lamp, launched in the 1983 IKEA catalogue, the CIRKEL pendant lamp from 1978, and the BANJO table, wall and clip-on lamp.

Louis Poulsen
Louis Poulsen is a Danish lighting manufacturer with roots going back to 1874, when Ludvig R. Poulsen founded a business in Copenhagen. Originally a trading company, the firm gradually shifted towards electrical supplies and lighting as electricity became more widely used. In 1896 Ludvig’s nephew Louis Poulsen joined the company, and after Ludvig’s death in 1906 Louis continued the business. In 1914Sophus Kaastrup-Olsen became a partner, and the company name changed to Louis Poulsen & Co.
A decisive turning point came in 1924, when Poul Henningsen began his long collaboration with the company. His scientific approach to glare-free lighting and reflective multi-shade systems became central to the identity of Louis Poulsen and strongly influenced modern lighting design. Since then, the company has continued to combine functional light, architectural clarity and carefully considered form, following the idea that a lamp should not merely be an object, but a tool to shape light.
Over the decades, Louis Poulsen has produced both iconic domestic lighting and large-scale architectural lighting for public and professional spaces. The company remains one of the best-known names in Danish lighting design, with a strong emphasis on the quality, direction and atmosphere of light.
