Biography

• James Dyson set out to invent a better vacuum cleaner in 1978, after getting frustrated with his family's vacuum, using a cyclone to lift dirt.
• He's since expanded into a wide range of innovative appliances, including a popular line of intelligent air purifiers whose data Dyson claims to have used to create the most accurate picture of indoor air quality worldwide.
• Dyson now employs thousands of engineers around the world and said in 2020 it would invest the equivalent of $14 million a week on product development through 2025.
• In 2019 Dyson scrapped plans to build electric cars after telling staff they were not commercially viable.
• Dyson, who attended art school in London, does not have an engineering degree.
• After five years of testing and 5,127 prototypes, Dyson invented the world's first bagless vacuum cleaner.
• Dyson's first vacuum was so powerful that its inner-cyclone mechanism separated air and dust at a speed of 924 mph and could pull cigarette smoke from the air.
