Sir James DysonBorn 2 May 1947. English engineer and industrial designer whose inventions include the Dual Cyclone bagless vacuum cleaner and the Airblade hand dryer. He founded Dyson Research Ltd. in 1979. Since 1970, when he re-invented the wheelbarrow as his Ballbarrow, he pursued his passion to create new products that function better than anything before them. He launched a bagless vacuum cleaner made and sold in Japan in 1986. When introduced in Britain in 1993, his vacuum cleaner became the country's best-selling by early 1995. Similarly, when sold in the U.S. from 2002, it captured 20% of the market by early 2005. His company now employs about 1400 people to develop new, more practical inventions.« |
