The famous explorer who started his journey to the West from Saint Louis is Meriwether Lewis. He, along with William Clark, led the historic Lewis and Clark expedition in 1804-1806 to explore and map the newly acquired western territories of the United States.

That is correct! Meriwether Lewis, along with William Clark, led the Lewis and Clark Expedition, which began from Saint Louis in 1804. The expedition was commissioned by President Thomas Jefferson and aimed to explore and map the newly acquired Louisiana Territory, as well as find a practical route to the Pacific Ocean. Their journey took them through present-day states such as Missouri, Kansas, Nebraska, Montana, Idaho, Oregon, and Washington.
