Frobenius Orgelbyggeri (Th. Frobenius & Sons / Th. Frobenius & Sønner Orgelbyggeri A/S) was founded in Copenhagen by Theodor Frobenius (1885–1972) in 1909. The firm moved to Lyngby in 1925. Theodor's sons Walther and Erik joined the company in 1944, at the same time that they began to build organs in the classical tradition, with mechanical actions and slider windchests. They build organs with characteristic modern casework, usually arranging the pipework of each manual such that three to six repeating arrangements of front pipes are shown in the façade. Their organ development after 1925 was in the style of the Organ Reform Movement and neo-classical design.
