Flentrop is a Dutch company based in Zaandam that builds and restores organs.
The company originated in 1903 when Hendrik Wicher Flentrop[1] (1866-1950) from Koog aan de Zaan, originally a house painter by trade, and organist at the Westzijderkerk in Zaandam, started a piano and organ company.
Beginning in 1922 he corresponded with Albert Schweitzer, which resulted in pronounced opinions concerning the demands which had to be made on the organ.
In addition he built numerous instruments in the United States (most notably those in Adolphus Busch Hall at Harvard University,[2] and in St. Mark's Cathedral, in Seattle, Washington[3][4]), and restored two in Mexico City.
Tasks were also carried out in foreign countries: Taipei, Riga, Tokyo, Dunblane, Kazan, and Yerevan.
