Danish Silver Trumpet Ceiling Lamp attributed to Claus Bonderup & Torsten Thorup for Fog & Mørup

Danish modern lighting manufacturing company Fog & Mørup was founded by Ansgar Fog (1880 to 1930) and Erik Mørup (1879-1972) in Aarhus, Denmark in 1904. In its first incarnation, the company operated as a metalwork wholesaler. In 1906, the pair moved to Copenhagen and began to focus on lighting production, over the years buying up a number of electrical and lighting companies. The company continued to expand steadily through World War II. One of the most successful Fog & Mørup products from the pre-war era was the Kongelys Lamp, named for the Danish King Christian X in honor of his 25th jubilee in 1937.

After the war—especially in the 1960s and ’70s—Fog & Mørup’s international reputation reached new heights. In 1959, Johannes (Jo) Hammerborg(1920-1982) joined as head of design and introduced modernist design principles to the Fog & Mørup collections. Streamlined, sleek forms become the company’s signature aesthetic, which was expressed in a range of lamps, pendants, and sconces designed by Hammerborg and other outside designers, like Jørgen Bo, Sophus Frandsen, and Torsten Thorup. Standout designs include the Semi Pendant by Thorup and Claus Bonderup (1967); the Falcon Pendant by Andreas Hansen (1967); and the Nova Pendant (1963), Trombone Lamp (ca. 1966), and Copper Kastor collection (ca. 1969-71) by Hammerborg.

In 1978, Fog & Mørup merged with leading Danish modern lighting manufacturer Lyfa, and Hammerborg retired in 1980. Through the course of the remaining years of the 20th century, the once pioneering Danish lighting brand lost steam as the company changed hands again and again. In 2005, following its final acquisition by Nordlux of Ålborg, Fog & Mørup official closed.
