The PH Artichoke is considered to be a classical masterpiece made by Poul Henningsen more than 40 years ago. The structure is made of twelve steel arches. On this structure PH placed 72 copper leaves in twelve circular rows with six blades in each row. Because each row is staggered from the previous, all 72 leaves are able to "cover for each other". This design allows viewing the fixture from any angle without being able to see the light source located in the center of the PH Artichoke. The original PH Artichokes were developed for a restaurant in Copenhagen called the Langelinie Pavilion, and they are still hanging there today.
Poul Henningsen was born in Copenhagen to the famous Danish actress Agnes Henningsen. He never graduated as an architect, but studied at The Technical School at Frederiksberg, Denmark from 1911-14, and then at Technical College
in Copenhagen from 1914-17.
his professional interests changed to focus mainly on lighting which is what he is
most famous for. He also expanded his field of occupation into areas of writing, becoming a journalist and an author. For a short period at the beginning of WWII, he was the head architect of the Tivoli Gardens in Copenhagen. But like many other creative people, he was forced to flee Denmark during the German occupation but soon became a vital part of the Danish colony of artists
living in Sweden. His lifelong collaboration with Louis Poulsen Lighting began in 1925 and lasted
until his death. To this day, Louis Poulsen Lighting still benefits from his genius. Poul Henningsen was also the first editor of the company magazine "NYT". The CEO of Louis Poulsen at the time, Sophus Kaastrup-Olsen, gave the magazine to PH as a gift because he had been terminated from the Danish newspaper he worked for (his opinions were too radical). Poul Henningsen's pioneering work concerning the relations between light structures, shadows, glare, and color reproduction-compared to man's need
for light remains the fondation of the lighting theories still practiced by Louis Poulsen Lighting.
