Dyson has become a byword for high performing products, technology, design and invention. Now, James Dyson, the inventor and entrepreneur who made it all happen, tells his remarkable and inspirational story in Invention: A Life.   Famously, over a four-year period, James Dyson made 5,127 prototypes of the cyclonic vacuum cleaner that would transform the way houses are cleaned around the world. In devoting all his resources to iteratively developing the technology, he risked it all, but out of many failures and setbacks came hard-fought success. His products - including vacuum cleaners, hair dryers and hair stylers, and fans and purifiers - are not only revolutionary technologies, but design classics. This was a legacy of his time studying at the Royal College of Art in the 1960s, when he was inspired by some of the most famous artists, designers and inventors of the era, as well as his engineering heroes such as Frank Whittle and Alec Issigonis.   In Invention: A Life, Dyson reveals how he came to set up his own company and led it to become one of the most inventive technology companies in the world. It is a compelling and dramatic tale, with many obstacles overcome. Dyson has always looked to the future, even setting up his own university to help provide the next generation of engineers and designers. For, as he says, 'everything changes all the time, so experience is of little use'.   Whether you are someone who has an idea for a better product, an aspiring entrepreneur, whether you appreciate great design or a page-turning read, Invention: A Life offers you inspiration, hope and much more.
