Harlin's son, John Harlin III, who was nine at the time of his father's death, is also a mountaineer and was the editor-in-chief of the American Alpine Club's American Alpine Journal. Harlin III, himself an accomplished climber and author of five books, recently climbed the Eiger by the original route. He has written a book about his experience entitled The Eiger Obsession. A film of the son's climb to exorcise the ghosts left by his father's death came out in May 2007: The Alps by Steve Judson and his Academy Award-nominated film team, is an Imax movie containing footage of the north face of the Eiger as well as other Alpine peaks. Harlin III returned to the Leysin American School where his father was sports director, as the director of the Alpine Institute.
