Some people thought I was crazy. Professor Clark had an idea to help some people to hear. The bionic ear. This required a tiny implant. It's very small. But it was only possible with help from telephone engineers here in Melbourne. They minute, trice the circuitry. And this led to the development of what we now know as the bionic ear. If we can have achieved that, can you imagine the wonderful things that we've all got to look forward to?
