Meriwether Lewis on August 18, 1774 near Charlottesville, Virginia. Lewis grew up among the forests and wilderness of the Shenandoah Valley and developed a love of hunting and exploring. Lewis became a soldier at an early age and fought in the Whiskey Rebellion of 1794. He soon became an officer in the Army and battled the Native Americans in the Northwest Territory of the new nation. Lewis became very educated about the Native Americans and even learned some of their languages.

As a neighbor and friend of the Lewis family, Thomas Jefferson appointed Meriwether Lewis as his personal secretary. He prepared Lewis for two years to explore the lands acquired in the Louisiana Purchase. Lewis studied plants, animals and navigation at the University of Pennsylvania in preparation. Lewis invited William Clark to co-lead the expedition.

Lewis and Clark spent over two years exploring the new frontier. After successfully establishing Fort Clatsop, Oregon, and after discovering over 300 news species of animals and plants throughout the Great Plains and western mountains, the pair returned. Meriwether Lewis was named the new governor of the Louisiana Territory. On October 11, 1809, Lewis was on his way to Washington D.C. when he mysteriously died at a hotel. Many believe he committed suicide, but others believe he was murdered.
