Frank Martin (15 September 1890 – 21 November 1974) was a Swiss composer, who lived a large part of his life in the Netherlands. He was born in Geneva, the tenth and last child of Charles Martin, a pastor. Before he started school, he was already playing the piano and improvising. At nine, he was composing complete, fully formed songs, without having had any instruction in song forms or harmony. A performance of Bach's St. Matthew Passion which he heard at the age of twelve left upon him an ineradicable impression, and Bach became his true master.
