The owner of the company that makes Segways died Sunday when he drove an off-road model of the vehicle off a cliff on his estate in West Yorkshire, England.
Heselden, whose estimated worth is more than $263 million and who was ranked 395 on the Sunday Times of London’s Rich List, bought Segway in January.
After working as a miner and engineer, Heselden invented a sort of Jersey Barrier for battlefields. The portable containment system is a wire cage that can be filled with earth and sand and used as a defense barrier to bullets, missiles, and suicide-bomber attacks. His company, Hesco Bastion, founded in 1990, has been very successful in selling the barriers to NATO nations, including the United Kingdom and the United States.
Heselden is survived by his wife, Julie, five children, and eight grandchildren.
