Poul Henningsen, known by his initials "PH," was born in 1894. He was a Danish designer who dedicated his entire career to researching the importance of light.
Although he never qualified as an architect, he designed houses, industrial buildings, and contributed to the Tivoli Gardens in Copenhagen.
He won a gold medal at the International Exhibition of Modern Decorative and Industrial Arts in Paris, where he presented a lamp with a multi-shade system designed to eliminate glare and provide soft, diffused light.
His most famous lighting designs include the PH lamp series, the PH Artichoke (Koglen) from 1958, and the PH5, also from 1958.
