Richard (or Rijk) Hol (23 July 1825, in Amsterdam – 14 May 1904, in Utrecht) was a Dutch composer and conductor, based for most of his career at Utrecht. His conservative music showed the influence of Ludwig van Beethoven, Felix Mendelssohn, and Robert Schumann and the Leipzig school, though as a conductor he offered Dutch audiences the more revolutionary music of Hector Berlioz and Richard Wagner.
Hendrik Franciscus Andriessen (17 September 1892 – 12 April 1981) 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.
