Alaskan adventurer who lived alone in a log cabin in the remote wilderness for close to 30 years.
He retired to the Twin Lakes region of Alaska at the age of 52 after working as a diesel mechanic.
His regular journal entries, complete with weather and local fauna observations, became published in a memoir called One Man's Wilderness, which became a classic about Alaska.
He was never married and had no children.
The state of Alaska frequently attracted men who preferred nature and solitude like Timothy Treadwell, the Grizzly Man.
