Jimi Heselden(1948 – September 27, 2010) was a British entrepreneur. A former coal miner, Heselden made his fortune manufacturing the Hesco bastion barrier system. In 2010 he bought Segway Inc., maker of the Segway personal transport system. Heselden was killed in 2010 from injuries apparently sustained while riding a Segway. His fortune was estimated at £166 million and he was ranked 395th in the Sunday Times Rich List.

He accidentally reversed his motorised two-wheel Segway scooter over a cliff - to move out of the way of a walker.
The kind-hearted tycoon then plunged 50ft to his death.
