Willem Nicolaas Frederik Sibmacher Zijnen (20 May 1859 - 27 June 1926) was a Dutch journalist and increasingly, towards the end of his career, a music critic.
[1] Willem Nicolaas Frederik Sibmacher Zijnen was born in Middelburg (Zeeland).
In June 1902 he crossed the border in order to attend the premier of third symphony at Krefeld on behalf of his newspaper.
[4] Mahler was widely regarded as "too modern" by concert audiences at this time, but Sibmacher Zijnen was an enthusiast.
In other contributions to the paper he was at pains to praise the symphonic works of Mahler and bemoan the lukewarm reactions they generated in Dutch concert halls.
