George Gershwin couldn't seem to stay out of trouble when he was a boy. He was a tough kid who got in a lot of fights and frequently skipped school. When his family bought a piano, his life was transformed. He quickly mastered the instrument, and then dropped out of school when he was fifteen to become a musician. Within a year, he had sold his first song. When he was 20, he wrote his first big hit. Five years after that, Rhapsody in Blue catapulted him to international fame. With his brother Ira as lyricist, George went on to compose some of the most famous musicals of the twentieth century, and he wrote several movie scores.
