Vintage PH 4/3 Pendant Lamps by Poul Henningsen for Louis Poulsen, 1966, Set of 2

Designer and architect Poul Henningsen was born in Copenhagen in 1894, the illegitimate son of satirical novelist Carl Ewald and feminist activist and writer Agnes Henningsen. He studied at the Frederiksberg Technical School from 1911 to 1914, and then at the Copenhagen Technical College until 1917. Early on in his career, he worked as both an architect and a journalist, but quickly became fascinated by lighting design, inspired by the then-new technology of the electric light bulb. He approached lighting from a scientific standpoint, investigating the impact that soft, diffused light had on one’s well being.

In 1925, Henningsen began what would become a lifelong collaboration with Copenhagen-based lighting company Louis Poulsen, for whom he produced over one hundred lamps, all belonging to the PH series, and all based on the idea of multiple shades and diffusors to provide warm, soft light. For a short time at the beginning of World War II, Henningsen was the head architect of the Tivoli Gardens in Copenhagen. However, he was forced to flee Denmark during the German occupation, and moved to Sweden.

Among his best known works are the 1958 PH Snowball, a pendant lamp with eight aluminum shades, and the 1957 PH Artichoke lamp, a pendant lamp with a bulb surrounded by scale-like reflectors—both iconic examples of Scandinavian modernist design. Henningsen's work can be found in major museum collections around the world, including MoMA, Vitra, and the V&A. He passed away in Denmark in 1967.

Now recognized as one of the world’s foremost lighting manufacturers, Louis Poulsen began its long life in 1874, first as the Copenhagen Direct Wine Import Company, and then, starting in 1896, as an electrical components and tools supplier. In the 1910s, Louis Poulsen (1871-1934), nephew of the Copenhagen-based company’s original founder, took over and soon after became partners with entrepreneur and electricity enthusiast Sophus Kaastrup-Olsen (1884-1938). Together they reincorporated as Louis Poulsen & Co. In 1917, Kaastrup-Olsen acquired Poulsen's shares and became the company’s sole proprietor, just in time to benefit from the increasing demand for electrically powered fixtures that developed during and after World War I.

In 1924, Kaastrup-Olsen began collaborating with Danish architect Poul Henningsen (1894-1967) on the design of an innovative, three-shade lamp system, after Henningsen was chosen to participate in the legendary Exposition Internationale des Arts Décoratifs et Industriels Modernes to be held the following year in Paris. Henningsen won the gold medal there, and his work with the Louis Poulsen & Co. grew into a lifelong collaboration that remains the foundation of its ongoing production today.

Henningsen was obsessed with light and considered himself a “lighting architect.” With his PH Lamp series, he sought to create glare-free yet direct light where it was most needed, accompanied by soft shadows, lit by the then-new incandescent bulbs. He did not just design a light, but an entire system; around a thousand different models have been designed over the years. Pioneering and timeless classics such as Henningsen’s Artichoke Lamp (1958) and the PH5 (1958), as well as fellow Danish designer Verner Panton’s Ceiling Flower Pot lamp (1968) and Panthella table lamp (1971), are considered to be among the most iconic Scandinavian contributions to modern design culture.

Louis Poulsen—beloved by design lovers around the world—continues to specialize in the development and production of lighting solutions for indoor and outdoor applications. With function, comfort, and ambience at the core of each design, the company’s products can be found in numerous design museum collections, including MoMA (New York), Cooper Hewitt (New York), Philadelphia Museum of Art, Indianapolis Museum of Art, Museum of Decorative Arts (Copenhagen), Design Museum (London), and Vitra Design Museum (Weil am Rhein). Today Louis Poulsen is part of Polaris Private Equity.
