Timothy Treadwell was an American environmentalist and documentary maker, who was mauled by the same bear he was supposed to study.
Until this point, nothing seems unusual. You step the invisible line Mother Nature sets for you, and you receive a punishment. However, Timothy Treadwell was not your average city folk that fails to understand the wilderness. With 13 summers spent studying the grizzly bears of Katmai National Park in Alaska, Timothy was probably the person with the most accurate understanding of the beasts’ behavior.
He died together with his visiting girlfriend, Amie Huguenard, and the horrific scene got an audio recording. “Grizzly Man,” by Werner Herzog, is a documentary to watch if you want more on the topic.
