German silversmith Christian Dell was a metalworking teacher at the Bauhaus from 1922–25. Collaborating with modernist luminaries László Moholy-Nagy and Marianne Brandt, Dell helped shape the Bauhaus approach to industrial lighting. He started designing lighting for various companies in 1926, including Gebrüder Kaiser & Co., the one that produced the first lamp in the Kaiser-idell Collection (1931). With the first part of the name being for the factory that produced it, the latter is an amalgam of Dell and idee, the German word for “idea.” Brought back into production by Fritz Hansen in 2011, the collection is crafted to the designer’s original specifications, including his worldwide-patented swivel joint for shade adjustability – revolutionary in 1931. Bulb (not included): 4" or shorter LED; E26 base; 25W max. UL Listed. Made in Denmark.
