Hendrik Franciscus Andriessen was a Dutch composer and organist. He is remembered most of all for his improvisation at the organ and for the renewal of Catholic liturgical music in the Netherlands. Andriessen composed in a musical idiom that revealed strong French influences. He was the brother of pianist and composer Willem Andriessen and the father of the composers Jurriaan Andriessen and Louis Andriessen and of the flautist Heleen Andriessen.
