Sir James Dyson is best known for inventing the Dual Cyclone bagless vacuum cleaner, an idea which led to the brink of bankruptcy to then become a billion-dollar business. He thrives on developing products that work significantly better and today is recognised for bringing new technology to the vacuum, fan, heater and hand dryer categories. His global James Dyson Foundation has also played an active role in encouraging aspiring engineers and inventors around the world.
