Frequent layoffs made work in the Hibbing, Minn., iron mines too stop-and-go for Carl Eric Wickman, a Swedish immigrant. So he became the local dealer for Hupmobile cars -- and found he had a product that wouldn't move. To get business rolling, he bought a seven-passenger Hupmobile in 1913 and offered miners 15? rides to a saloon in a nearby town. By 1922, he had sold his transportation business for $60,000 and moved to Duluth. There, he began to buy up local bus lines under the name Motor Transit Corp., which in 1930 became known as The Greyhound Corp.
