Flemish composer and violinist Carl Rosier wa active mainly in Germany. From about 1664 he was a violinist at the court of the Elector Maximilian Heinrich in Bonn and later became vice-Kapellmeister there. From 1675 he lived principally in Cologne, but from about 1683 to 1699 he also worked in the Netherlands, where he was highly regarded as a violinist and numbered Carolus Hacquart among his colleagues.

On a title-page of 1691 he is described as vice-Kapellmeister at the court at Cologne. In 1967 he participated in a collegium musicum in Amsterdam together with Nicolas Desrosier, Hendrik Anders, N.F. Le Grand and others. In 1699 he was Kapellmeister of Cologne Cathedral and in 1701 was appointed to a similar post by the city council: he thus held simultaneously the two most important positions in the musical life of Cologne. His daughter Maria Anna married Willem de Fesch.
