Meriwether Lewis and William Clark are most famous for leading the expedition that began in St. Louis in 1804, took them up the Missouri River, over the Rocky Mountains to the west coast and back.

But their connection with St. Louis didn’t end there. In 1807, Thomas Jefferson appointed Lewis and Clark to leadership positions in the Louisiana Territory, with a home base in the St. Louis region.
