Karl Friedrich May ( /maɪ/ MY; ; 25 February 1842 – 30 March 1912) was a popular German writer, noted mainly for adventure novels set in the American Old West (best known for the characters of Winnetou and Old Shatterhand) and similar books set in the Orient and Middle East (with Kara Ben Nemsi and Hadschi Halef Omar). In addition, he wrote stories set in his native Germany, in China and in South America. May also wrote poetry and a play, and composed music; he was a proficient player of several musical instruments. Many of his works were filmed, adapted for the stage, turned into audio dramas or into comics. A highly imaginative and fanciful writer, May never visited the exotic places featured in his stories until late in life, at which point the clash between his fiction and reality led to a complete change in his work.
Asteroid 15728 Karlmay is named in his honor.
