Omaha's pioneer period began in 1854, when the city was founded by speculators from neighboring Council Bluffs, Iowa. The city was founded along the Missouri River, and a crossing called Lone Tree Ferry earned the city its nickname, the "Gateway to the West". Omaha introduced this new West to the world in 1898, when it played host to the World's Fair, dubbed the Trans-Mississippi Exposition. During the 19th century, Omaha's central location in the United States spurred the city to become an important national transportation hub. Throughout the rest of the 19th century, the transportation and jobbing sectors were important in the city, along with its railroads and breweries. In the 20th century, the Omaha Stockyards, once the world's largest, and its meatpacking plants gained international prominence. Today, Omaha is the home to the headquarters of four Fortune 500 companies: mega-conglomerate Berkshire Hathaway; one of the world's largest construction companies, Kiewit Corporation; insurance and financial firm Mutual of Omaha; and the United States' largest railroad operator, Union Pacific Corporation. Berkshire Hathaway is headed by local investor Warren Buffett, one of the wealthiest people in the world, according to a decade's worth of Forbes rankings, some of which have ranked him as high as No. 1.Omaha is also the home to five Fortune 1000 headquarters: Green Plains Renewable Energy, TD Ameritrade, Valmont Industries, Werner Enterprises, and West Corporation.
