10. In a car
Who: Clärenore Stinnes and Carl-Axel Söderström
A German car racer and a Swedish cinematographer respectively, Stinnes and Söderström were the first to ever travel around the world by automobile. During their 27,000-mile voyage, which was sponsored by the German auto industry and began in Berlin, they traversed Siberia, the Gobi desert, Japan, and made their way to South America via ferry. Before making it back to Europe, they trekked up and eastward from Vancouver, and were warmly welcomed by President Hoover in a show of support.
