Poul Henningsen (1894–1967) was an influential Danish designer and cultural figure, best known for his groundbreaking work in lighting design. His enduring legacy is founded on the "PH Lamp" series, introduced in 1925, which revolutionized the way light is diffused in interiors. Henningsen's meticulous attention to the quality of light and its effects on surroundings led to the creation of the iconic "Artichoke Lamp" (1958), a masterpiece of design that remains a symbol of sophistication and innovation.

'House of the Future' Ceiling Lamp

History:
Designed in 1959 exclusively for 'The House of the Day after Tomorrow' exhibition, with only around 15 lamps ever produced. Reminiscent of the Artichoke Lamp in the Langelinie Pavilion. Lighting engineering based on color concept, based on the observation that the red end of the light spectrum reproduced texture better than the colder color rays.

Furniture

Unique Dining Table

History:
The idea behind the hexagonal and three-legged design was that several tables could be placed next to each other, without the table legs getting in the way of the people seated at the tables. Poul Henningsen designed this one table and had it produced by a cabinetmaker with the intention of putting it into serial production. This never happened though, and this is thus the only piece ever made.

'Septima Five' Light

History:
Beyond the original PH Lamps, Poul Henningsen worked on the Septima between 1927 and 1931. Here again, he cloaked the bulb in several layers that simultaneously diffuse and reflect light to create a warm and harmonious ambiance. The commercial and cultural potential of the Septima was never fully realized, and very few examples were produced. First came the model with clear glass shades, in 1929 the model with amber coloured shades was introduced and in 1930-31 came the one with pink shades. The smaller version 'Septima 4' was introduced in 1931. On the eve of World War II, Louis Poulsen ceased production due to material shortages.
