Poul Henningsen (9 September 1894 – 31 January 1967) was a Danish author, critic, architect, and designer, who was one of the leading figures of the cultural life of Denmark between the World Wars. In Denmark, he often is referred to, simply, as PH. PH's most valuable contribution to design was in the field of lighting. He designed the PH-lamp in 1925, which, like his later designs, used carefully analyzed reflecting and baffling of the light rays from the bulb to achieve glare-free and uniform illumination.
