Guillaume Lekeu (January 20, 1870 – January 21, 1894) was a Belgian (Wallon) composer of classical music. Lekeu, who was born in Verviers, Belgium, took his first lessons at the conservatory in that city. In 1879, his parents moved to Poitiers. There, he finished school while he continued his music studies autodidactically. At the age of 15, he composed his first piece. In 1888, his family settled down in Paris where Lekeu became a student of César Franck. After Franck's death, Vincent d'Indy became his new teacher. In 1891, he obtained a second Second Prix de Rome for his cantata Andromède.
