From Silence to Sound: Graeme Clark's Cochlear Implant.

Graeme Clark is an exceptional Australian professor and otolaryngologist who spent most of his life researching a way to help his deaf father and others suffering from profound hearing loss gain a better connection to those around them. His invention, the cochlear implant, has changed the lives of over 300,000 people around the world, with more than half of those individuals being children. Clark successfully created the first sensory connection linking the external world with human consciousness.
