Was Claude Debussy a conductor?

No, he was a composer. He was born in France in 1862 and died in 1918. Debussy was one of the most prominent figures working within the field of impressionist music, though he himself intensely disliked the term when applied to his compositions. Debussy is not only among the most important of all French composers, but also a central figure in European music at the turn of the 20th century.
