Coolsma, Hans [Johannis] (Tennis)
- Maurice Byrne
(b Coevorden, Netherlands, 1919; d Coevorden, Netherlands, 1991). Dutch recorder maker. He made his début as an oboe and recorder player in 1947 and in 1951 obtained the oboe diploma of the conservatory in Utrecht, after studying with Ferdinand Pels. In 1946 he opened a music shop in Utrecht, later known as the Nederlands Centrum Blokfluit (Dutch Recorder Centre), where in 1951 he started making recorders (the ‘Aura’ range) and flutes. He aimed to build recorders using modern precision machinery but aspiring to the standards of the traditional artist craftsmen. His solo instruments were received with acclaim and were adopted by such players as Frans Brüggen. In designing recorders he imitated historical models, interpreting (but not slavishly copying), at modern and low pitches, instruments by the best Baroque masters, notably Bressan. He used both traditional materials and machined polyester, and also restored historical instruments. In 1990 he transferred his business to the recorder manufacturer and retailer AAFAB BV in Utrecht....
