Carel Christiaan Wilhelm Mann ( July 23, 1871 in Amsterdam ; November 30, 1928 in The Hague ) was the first Dutch chess composer of international importance. After leaving school, he worked as a butcher in his father's butcher shop. He initially played tournament chess passably, and in 1892 he began composing chess problems and endgame studies . Some of his studies became internationally known and won awards.

173 studies and 62 chess problems were published. Many of his studies showed two queens and some pieces, and he liked to work on Zugzwang themes .
