Angus david great inventors

Nine remarkable men produced inventions that changed the world. The printing press, the telephone, powered flight, recording and others have made the modern world what it is. But who were the men who had these ideas and made reality of them? As David Angus shows, they were very different - quiet, boisterous, confident, withdrawn - but all had a moment of vision allied to single-minded determination to battle through numerous prototypes and produced something that really worked. It is a fascinating account for younger listeners.
