90 years - 3 designers - 3 designs
For Louis Poulsen 2017 is in many ways a unique year. It is the year where we celebrate the 90th year anniversary of Poul Henningsen’s PH 3/2 Table Lamp, the 60th anniversary of Arne Jacobsen’s AJ lamp and the launch of the Above lamp.
To pay a tribute to the PH 3/2 Lamp and AJ Lamp new editions have been launched this spring.
Arne Jacobsen
Arne Jacobsen (1902-1971) was one of Denmark’s most famous and acknowledged modernist architects and designers. He graduated from the Royal Danish Academy of Fine Arts in 1927 and ventured into various design fields, such as light fixtures, furniture, cutlery, fabrics, and wallpaper patterns.
His break-through as a furniture designer came in 1952 with ‘The Ant’ for Fritz Hansen and was succeeded with ‘Series 7’ in 1955.
Together with the AJ Lamp, two of his most famous chairs, ‘The Egg’ and ‘The Swan’, were designed for his SAS Royal Hotel in 1957.
He was remarkably productive and created more than 300 works encompassing all genres of design.
Poul Henningsen
PH (1894-1967) was born in Copenhagen, son of the famous Danish authoress Agnes Henningsen. He studied six years at the technical schools in Copenhagen, but never completed a degree in architecture.
PH originally practised traditional architecture, in the functionalistic style that was beginning to prevail. Over the years he began to focus primarily on designing lamps and practising journalism with his radical opinions.
PH’s lifelong partnership with Louis Poulsen began back in 1924 with the Paris lamp, which won the first prize at the World Exhibition in Paris. The PH 3/2 Table Lamp was designed in 1927, and is still a part of the Louis Poulsen PH Lamp assortment.
Mads Odgård
Mads Odgård (b. 1960) is a well-established Danish designer. He graduated from the School of Design at the Royal Danish Academy of Fine Arts in Copenhagen and Art Center Europe, Switzerland.
Since 1988, the Mads Odgård Design Studio has focused on product design with a mission to improve what already exists and most importantly to give the user spontaneous delight. More than anything, he believes that excellent design must be logical and functional if it is to endure. Odgård believes that design can be successful only when comfort, technology, ergonomics, ecology, economics and aesthetics are in balance.
Mads Odgård has previously designed professional lamps for Louis Poulsen such as the LP Icon and MO500. The Above Lamp is the first lamp Odgård have designed that both suit the professional and private market. The Above Lamp embodies Odgård’s mantra: How simple do you dare to design?
