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.
As the organist at St. Catherine's Cathedral, Utrecht, he became well known for his improvisation abilities. From 1926 to 1954, he lectured in composition and music theory at the Amsterdam Conservatory while also teaching at the Institute for Catholic Church Music in Utrecht between 1930 and 1949.
He was the director of the Utrecht Conservatory from 1937 to 1949.
During World War II the only musical activities he was allowed were to give lessons and to accompany church services.
He wrote the Intermezzi in two periods: two books (1935 and 1943–46)
