Founded in 1894 by Olof Lindholm, a Swede who had come to Germany with Theodor Mannborg and Lars Magnus Hofberg. Lindholm worked for Mannborg until establishing his own factory. He retired in 1911 and sold the factory to Gustav Weischet, ... Lindholm acquired Hofberg in 1930, Mannborg in 1961, and the reed-making machinery of Deutsch Harmonium-Zungen-Fabrik in 1969. Lindholm managed to operate as a privately owned business until 1972 when it was taken over by the German Democratic Republic and became a part of the state musical instrument making consortium VEB Leipziger Pianoforte fabrik Böhlitz-Ehrenberg, (qv). The factory was restored to private ownership in 1993, and is now manufacturing historical keyboard instruments.“

In 1894 when Mannborg moved to Leipzig, Olaf Lindholm stayed behind in Borna and established his own factory. Lindholm retired in 1911 and sold his factory to Gustav Weischet, ... in 1972 Lindholm was taken over by the government monopoly, which had been renamed VEB Deutsche Piano-Union Bölitz-Enrenberg. Reed organ manufacturing was discontinued and the machinery moved or broken up. The original factory building still exists at the time of this writing; and since the fall of the communist government the last private owner, Joachim Weischet, has recovered ownership and turned it into a harmonium museum.“
