THE FIRST EFFORT to build an organ in colonial South Africa occurred in 1720, but the plan for a Dutch instrument to be installed in the Groote Kerk in Cape Town never came to fruition. Because of the impact of the Reformation in Europe, no organs were constructed in South Africa before 1735.1 Evidence suggests that the first documented organbuilder in the country was Johann Jacob Posse (Poosen), who emigrated from Eisleben, Germany, and whose ship docked in Cape Town in 1735. The largest free-standing organ in South Africa in terms of structural design is found in the Feather Market Centre in Port Elizabeth. ...many South African organs during the 1970s and 1980s were characterized by fresh, natural, and unforced tone.12 However, the tonal features of this newly-found sound idiom were not appreciated in all circles and began eliciting various levels of criticism in the organ fraternity. Paul Ott built other significant organs in South Africa based on Orgelbewegung principles:16 Evangelisch-Lutherische Kirche St. Petri in Paari (1962, И/Р/10) Deutsche Evangelisch-Lutherische Kirche in Kroondal (1964, II/P/14) Deutsche Evangelisch-Lutherische Kirche in Mossel Bay (1971, II/P/17) Deutsche Evangelisch-Lutherische Kirche in Pretoria (1973, II/P/21) The Kroondal organ was donated to the congregation by Bayer, the German pharmaceutical company.17 Ott also built a number of practice organs for the music departments of the University of Stellenbosch (two in 1967), the University of the Free State (two in 1970), and the University of Pretoria (one in 1970).18 MARCUSSEN & SØN The internationally acclaimed Danish firm Marcussen & Søn was established in 1806 by Jürgen Marcussen (1781-1860).
