Marcussen & Søn

Aside from their many instruments in Denmark, they have built organs in northern Germany, Sweden, Finland, the Netherlands, Great Britain, South Africa, Japan, and the United States.

The company has been based in a house in the small town of Åbenrå, in southern Jutland, since 1830.

Several organs built in Scandinavia and North Germany in their first decades are still in use today, the oldest dating from 1820.

[1] The guiding figure behind the change was Sybrand Zachariassen (1900–1960), who took over management of the firm in 1922 at the age of 21.

Their new organs are based on classical organ-building traditions, with reliable slider windchests, simple mechanical "tracker" action with precise function, and a wide sound spectrum.
