William Becknell (1787 or 1788–1856, Amherst County, Virginia) was a freighter and the first white man to open what became known as the Santa Fe Trail to trade. Becknell left Franklin, Missouri in September 1821 on his first trip the western US with a load of freight to deliver to Santa Fe, New Mexico. The next year Becknell left Franklin with party of traders on a trip that was to open up the Santa Fe Trail to regular traffic and military movement. It became the first and only international trade route between The United States and Mexico until a railway to Santa Fe was built in 1880. He became known as the Father of the Santa Fe Trail.
