The great tower fire in the German Church in October 1878 completely destroyed the tower, the organ and the gallery. A new organ was designed by organ builder Per Larsson Åkerman and was completed in 1884. This organ was typical of Swedish contemporary organ building tradition, with both tonal and technical solutions inspired by German, French and English organ builders, some of them unique in Sweden. Despite the relatively small number of voices, the organ's sound was symphonic and orchestral. This type of organ came to be strongly questioned by the "Orgelbewegung" - the Organ Movement (which can best be described as the "Back to Nature" of organ history), which arose in Germany in the 1920s. In this spirit, the organ was redesigned in 1959, replacing a number of typically romantic, soft-sounding stops with more sharp and "baroque" sounding voices (e.g. the pointed flute and krummhorn). In 1971, the decision was made to build a completely new organ in the organ movement style. In the 1960s and 1970s, many Romantic organs were scrapped and replaced by poorly crafted instruments. Only three organs from the late 19th century were preserved in the Diocese of Stockholm. The Åkerman organ in the German Church was stored in the parish basement in 1972. There are now plans to document, restore and supplement, and to reinstall the historic Åkerman organ. This will also restore the architectural homogeneity of the church. In connection with the inauguration, a scientific documentation of the organ will be published.
