Leopold Stokowski was a conductor famous for leading orchestras with only his bare, expressive hands instead of a baton, sculpting the music in the air. He led the Philadelphia Orchestra to a lush, glowing sound and brought classical music to millions by conducting the music for Disney's film Fantasia. In the early 1930s he partnered with Bell Laboratories on pioneering experimental stereophonic recordings with the Philadelphia Orchestra, helping lay the groundwork for modern high-fidelity sound. He kept conducting with full energy into his nineties, always chasing new sounds.
