The municipality of Richterswil is located on Lake Zurich in the canton of Zurich in Switzerland. The current Protestant Reformed church was built between 1902 and 1904 in neo-Gothic style and consecrated in 1905. In 1904, the organ building company Carl Theodor Kuhn from Männedorf furnished this church with a romantic organ comprising 31 stops on three manuals and pedal with pneumatic action.
Sixty years later, the instrument was regarded as outdated. Its technical condition had deteriorated and it no longer met the needs and tastes of the time. It was therefore decided to have a new organ built. The contract for this was again awarded to the Kuhn company in Männedorf. The new instrument was inaugurated in December 1971 and has 42 stops on three manuals and pedal. As a progressive compromise for the time, the third manual was designed as a French-style swell, as indicated by the French names of the reed stops in the swell. The instrument allows for the performance of a wide range of repertoire, from early music to Romanticism and modern music. The instrument's versatility was enhanced by the fine voicing of Kurt Baumann, the former voicer at Kuhn, who invested a great deal of time in the Richterswil instrument. Project management and disposition were in the hands of organist Hansjürg Leutert, who was appointed organist at the Protestant Reformed Church in Richterswil in 1974 and remained there until his retirement in 2000. The Goll AG company from Lucerne carried out a general overhaul of the organ in 2018 and continues to maintain the Richterswil instrument to this day.
