Wells, Fargo & Company, in United States history, an express company that was active in the development of the Far West. It was set up in 1852 by the owners of the American Express Company to operate in California and between California and the East. The company carried gold, mail, and passengers and did banking for the California gold miners.
Wells, Fargo & Company was merged with other express companies during World War I, but continued to operate as a separate company for a time in Mexico and Cuba. An offshoot of the company, similarly named, entered the business of transporting money by armored cars in New York City and elsewhere. A California bank is also named Wells Fargo.
