American composer, musician, and pianist
According to Wikipedia,
Scott Joplin was an American composer and pianist. Because of the fame achieved for his ragtime compositions, he was dubbed the "King of Ragtime." During his career, he wrote over 40 original ragtime pieces, one ragtime ballet, and two operas. One of his first and most popular pieces, the Maple Leaf Rag, became the genre's first and most influential hit, later being recognized as the archetypal rag. Joplin considered ragtime to be a form of classical music and largely disdained the practice of ragtime such as that in honky tonk.
