Don Campbell was an author and entrepreneur. His book, The Mozart Effect: Tapping the Power of Music to Heal the Body, Strengthen the Mind, and Unlock the Creative Spirit spawned a business designed to enhance children's creativity and performance. The Mozart Effect states that "music is not just entertainment, it is medicine." The book unifies medicine, Eastern wisdom, and the new science of sonic healing. The text offers accounts of doctors and others who use music to deal with everything from anxiety to cancer, chronic pain, and even mental illness.
Campbell died in June 2012 of pancreatic cancer.
