His lifelong collaboration with Louis Poulsen began in 1924 and lasted until his passing. To this day, Louis Poulsen still benefits from his genius and continues his heritage working to provide exceptional, glare-free light. In fact, Poul Henningsen's pioneering work concerning the relationship between light, shadows, glare, and color reproduction - compared to man’s need for light laid the foundation of the lighting philosophy still practiced by Louis Poulsen.
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 Henningsen as a gift because he had been terminated from the Danish newspaper he worked for, because his opinions were too radical.
