Perhaps not a well known name in the UK, but a genuine Mountain Bike pioneer and bicycle inventor/innovator.
His wife (Jacquie Phelan) is better known and has visited Edinburgh and met several people on this forum.

In early August, 2015, Charlie Cunningham, bicycle builder, inventor and all around amazing person, fell off his bike and sustained several serious injuries.
Charlie suffered broken bones, bruises, and trauma to his head. At the time, he didn't feel his head injury was significant. Unfortunately, six weeks later, the head injury manifested into a subdural hematoma, a life threatening condition that resulted in emergency brain surgery.
