Alphonsus Johannes Maria Diepenbrock (2 September 1862 in Amsterdam – 5 April 1921) was a Dutch composer, essayist and classicist. Life and work Diepenbrock was not a musician by training. Brought up in a prosperous Catholic family, although he showed musical ability as a child, the expectation was that he would enter a university rather than a conservatory. And so he studied classics at the University of Amsterdam, gaining his doctorate cum laude in 1888 with a dissertation in Latin on the life of Seneca. The same year he became a teacher, a job which he held until 1894, and decided to devote himself to music. As a composer, he had been completely self-taught from an early age. He created a musical idiom which, in a highly personal manner, combined 16th-century polyphony with Wagnerian chromaticism, to which in later years was added the impressionistic refinement that he encountered in Debussy's music. His predominantly vocal output is distinguished by the high quality of the texts used. Apart from the Ancient Greek dramatists and the Roman Rite of the Catholic Church, he was inspired by, among others, Goethe, Novalis, Vondel, Brentano, Hölderlin, Heine, Nietzsche, Baudelaire and Verlaine. As a conductor, he performed many contemporary works, including Gustav Mahler's Fourth Symphony (at the Concertgebouw) as well as works by Fauré and Debussy. Diepenbrock is one of the Dutch composers whose name is displayed on the first balcony of the Amsterdam Concertgebouw. Throughout his life, Diepenbrock continued his interests in the wider cultural sphere, remaining a classics tutor and publishing works on literature, painting, politics, philosophy and religion. Indeed, during his lifetime his musical skills were often overlooked. Nonetheless, Diepenbrock was very much a respected figure within musical circles. He counted amongst his friends Mahler, Richard Strauss and Arnold Schoenberg. Alphons Diepenbrock is related to Cardinal Melchior von Diepenbrock, who was his great uncle, as well as to a branch of the family that immigrated to America in 1879. On 8 August 1895 in Rosmalen he married Lady Wilhelmina Elisabeth Cornelia Petronella de Jong van Beek en Donk.
