Hans Christian Andersen (April 2, 1805 – August 4, 1875) was a Danish author and poet. Although a prolific writer of plays, travelogues, novels, and poems, Andersen is best remembered for his fairy tales, a literary genre he so mastered that his works have been immortalized in children's world literature. Andersen's popularity was not limited to children, as his fairy tales—called eventyrs, or "fantastic tales"—express universal themes that transcend age and nationality.
