This course is for those wishing to learn more about the history and importance of Cambridge's thriving technology cluster. Christened a 'Phenomenon' by the Financial Times, our small city punches way above its weight. In the digital economy alone, Cambridge has the fifth highest turnover in the UK - ahead of cities such as Birmingham and Southampton. How did it get that way? Based on a range of material, including my two books about the evolution and global impact of the Cambridge Phenomenon, we'll explore how the early technology entrepreneurs got started, the challenges they had to overcome and how the Phenomenon 'grow'd like Topsy'. I'm hoping that at least some of the participants in this series of talks will have first-hand experience from their own careers, so am looking forward to sharing and learning at the same time.
