Who organized to carry mail across the US in 1860?

In 1860, the Pony Express was organized to carry mail across the United States. It was established by a partnership between William H. Russell, William B. WadDELL, and Alexander Majors, who aimed to provide a faster mail service between the East and West coasts. The service used a relay system of horseback riders to cover the 1,966 miles from St. Joseph, Missouri, to Sacramento, California, in a matter of days, dramatically reducing delivery times. Despite its short operation period, the Pony Express became an iconic symbol of American frontier spirit.
