Gerard Kockelmans (May 5, 1925 in Meerssen - September 7, 1965 in Beek), was a Dutch composer, conductor and music teacher.
He studied at the conservatoires of Maastricht, The Hague and Utrecht, where Kees van Baaren, Sem Dresden and Henri Geraedts were among his teachers.
Although he was clearly influenced and inspired by the twelve-tone music, which was very popular in his day, he never completely embraced this style.
Towards the end of his life, he practiced the so-called ‘serial’ style of composition, which he developed himself.
Amongst the choirs he conducted were the ‘Maartrichts mannenkoor’, ‘oratoriumvereniging Nieuw Leven’, ‘Mignon’ and ‘Maastrichter Staar’.
