John Coltrane
World War II so moved John Coltrane that he joined the army despite not receiving a conscription call. The jazz maestro undertook training at the New York naval station and was then posted at Pearl Harbor shortly after. It was during this period he fell in love with jazz music, and the unit assigned him the role of playing saxophone for their swing band.
After his stint with the Navy ended, he continued to perform and achieved great success in the world of music. All in all, we can say that Coltrane achieved a great deal in the four decades of his lifetime!
