Sir James Dyson OM CBE RDI FRS FREng FCSD FIET (born 2 May 1947) is a British inventor, industrial designer, farmer, and business magnate who founded Dyson. He is best known as the inventor of the bagless vacuum cleaner, which works on the principle of cyclonic separation. According to the Sunday Times Rich List 2023, he is the fifth richest person in the UK, with an estimated net worth of £23 billion. He served as the Provost of the Royal College of Art from August 2011 to July 2017, and opened a new university, the Dyson Institute of Engineering and Technology, on Dyson's Wiltshire campus in September 2017. Dyson helped design the Sea Truck in 1970 while studying at the Royal College of Art. His first original invention, the Ballbarrow, was a modified version of a wheelbarrow using a ball instead of a wheel. This was featured on the BBC's Tomorrow's World television programme. Dyson stuck with the idea of a ball, inventing the Trolleyball, a trolley that launched boats. He then designed the Wheelboat, which could travel at speeds of 64 kilometres per hour (40 mph) on both land and water. (Source: Wikipedia.org, CC BY-SA)
