George Hamilton Green Jr. (May 23, 1893 – September 11, 1970) was a xylophonist, composer, and cartoonist born in Omaha, Nebraska. He was born into a musical family, both his grandfather and his father being composers, arrangers, and conductors for bands in Omaha. From age four G.H. Green showed a prodigious talent as a pianist; he then took up the xylophone and by the age of eleven was being promoted as the “world’s greatest xylophonist” and was playing for crowds of 7,000-10,000. In 1915, when Green was 22 years old, a review in the United States Musician stated: "He has begun where every other xylophone player left off. His touch, his attack, his technique, and his powers of interpretation in the rendition of his solos being far different than other performers.
