Danish firm of organ builders. It was founded in 1909 at Copenhagen by Theodor Frobenius (1885–1972) and in 1925 moved to Lyngby near Copenhagen. In 1944, when his sons Walther and Erik joined the firm, it began building organs with mechanical key-action and slider-chests and mainly mechanical stop-action. It specializes in carefully designed modern casework with the characteristic feature that the pipework of each manual is arranged to present three to six repeating arrangements of front pipes. The characteristic neo-classical organ type, developed by the firm in the period from about 1925 to 1955, has inspired organ builders in other countries, especially in England and the USA. Important new organs built in Denmark include those at Thisted Kirke (1972), Ribe Domkirke (1973, enlarged 1994), St Mortens Kirke, Naestved (1975), Vangede Kirke (1979), and Opstandelseskirken, Albertslund (1992). Instruments built abroad include those at Queen's College, Oxford (...
