Happy birthday, Thor Heyerdahl

It is the birthday of Norwegian adventurer Thor Heyerdahl (1914), who sailed his raft Kon-Tiki 5,000 miles across the Pacific Ocean from Peru to the Polynesian islands to prove his theory that pre-Columbian people from South America could have settled the islands. Heyerdahl wrote a book about the 1947 adventure, and later an Academy Award-winning documentary film was made. The original raft is on display in Oslo.
