Poul Henningsen was born in Copenhagen by the famous Danish writer 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 practicing traditional functionalistic architecture, but over the years his professional interests changed to focus mainly on lighting which is what he is most famous for.
