(Gudgeon, Davey, Davey Gudgeon) Former Hogwarts student nearly lost an eye trying to touch the Whomping Willow.

Davey Gudgeon was a wizard and student at Hogwarts School of Witchcraft and Wizardry in the 1970s. He got his face scarred and almost lost his eye trying to get close enough to the Whomping Willow to touch its trunk. For their own safety (and possibly the Willow's as well), students were forbidden to go near the tree since that event occurred.
