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. He started practising traditional functionalist architecture, but over the years 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. 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.
