Christopher Johnson McCandless (; February 12, 1968 – c. August 1992), also known by the pseudonym Alexander Supertramp (Alex), was an American hiker who sought an increasingly itinerant lifestyle as he grew up. McCandless is the subject of Into the Wild, a nonfiction book by Jon Krakauer that was later made into a full-length feature film.
After graduating from college in 1990, McCandless traveled across North America and eventually hitchhiked to Alaska in April 1992. There, he set out along an old mining road known as the Stampede Trail with minimal supplies, hoping to live simply off the land. On the eastern bank of the Sushana River, McCandless found an abandoned bus, Fairbanks Bus 142, which he used as a makeshift shelter until his death. In September, his decomposing body, weighing only 30 kilograms (67 lb), was found by a hunter inside the bus. McCandless’s cause of death was officially ruled to be starvation, although the exact cause remains the subject of some debate.In January 1993, Jon Krakauer published McCandless’ story in that month’s issue of Outside magazine. He had been assigned the story and had written it under a tight deadline. Inspired by the details of McCandless’ story, he wrote and published the more extensive biographical book Into the Wild (1996), about McCandless’ travels. The book was subsequently adapted into a 2007 film directed by Sean Penn, with Emile Hirsch portraying McCandless. That same year, McCandless’ story also became the subject of Ron Lamothe’s documentary The Call of the Wild (2007).
