His parents, Yule and Ruth, migrated to the United States to escape the effects of World War II. He was born the oldest male of eight children.
A range-rider, it has been his job to protect his brother's cattle against a range of Alaskan wildlife, from bears to wolves and coyotes.
His younger brother, Otto Kilcher, appears alongside him on Alaska: The Last Frontier.
