Bent Gantzel-Boysen

Bent Gantzel-Boysen was head of Louis Poulsen’s design team in the 1970s, who stood behind lamps like the 1972 IT series and the PH 80 table and floor lamps, drawn in 1974, to celebrate Poul Henningsen’s (1894 – 1968) 80th birthday. He also designed the LamPetit table lamp in 1966. The design of the LamPetit lamp is often wrongly attributed to Verner Panton. You can find it over here.

Later in the 70s Bent Gantzel-Boysen went on to draw lamps for IKEA with his own firm. One of the more spectacular lamps from 1983 was the Duett pendant lamp with six coloured metal screens. You can find it over here. He designed lamps for IKEA in the period 19791987.
