When did Luis and clark die?

After the expedition, the two would lead completely different lives. Lewis, a troubled individual, was not suited for the bureaucratic life and found himself deep amongst petty and jealous administrators. On the way to Washington to clear his name, he stopped at Fort Pickering at the Chickasaw Bluffs. Those there described him as mentally distressed. Three weeks later, he was found in his rooms with two gunshot wounds at a roadside inn at Grinder's Stand, Hohenwald, Tennessee. He died the next morning on October 11, 1809, of two gunshot wounds. Some say that they were self-inflicted, others say it was murder. Jefferson -- for as long as he'd known the man -- admitted that he had suffered from "hypochondriac afflictions."

Clark would serve as governor of the Missouri Territory and he continued to lead Native American affairs for 30 years, enjoying a high reputation as an authority on the West. Many hunters, adventurers and explorers would visit him in St. Louis for advice. He died at age 69 on September 1, 1838, while at the home of his son, Meriwhether Lewis Clark.
