In 1792 while he was the secretary of state under George Washington he tried to get Dr. Moses Marshall to undertake this voyage across the continent but Dr. Marshall never made an attempt. Then one year later, Jefferson acting for the American Philosophical Society, sponsored the most promising attempt at that time. Jefferson sent Andrew Michaux, a French botanist, to find “the shortest & most convenient route of communication between the US. & the Pacific Ocean, within the temperate latitudes, & to learn such particulars as can be obtained of the country through which it passes, it's productions, inhabitants & other interesting circumstances” [1]. Unfortunately, Andrew Michaux got caught up in international issues and did not make it past the Mississippi. This would be the foundation as the Lewis and Clark expedition eleven years later.
In January 1803 Jefferson wrote a secret letter Congress asking for two thousand five hundred dollars for an expedition to the Pacific Ocean. Congress approved and for the first time Jefferson’s dream was to become reality.
