Meriwether Lewis (August 18, 1774 – October 11, 1809) was an American explorer, soldier, politician, and public administrator, best known for his role as the leader of the Lewis and Clark Expedition, also known as the Corps of Discovery, with William Clark. Their mission was to explore the territory of the Louisiana Purchase, establish trade with, and sovereignty over the natives near the Missouri River, and claim the Pacific Northwest and Oregon Country for the United States before European nations. They also collected scientific data, and information on indigenous nations.  President Thomas Jefferson appointed him Governor of Upper Louisiana in 1806.   He died of gunshot wounds in what was either a murder or suicide, in 1809.
Meriwether Lewis was born in Albemarle County, Colony of Virginia, in the present-day community of Ivy.  He was the son of William Lewis,  of Welsh ancestry, and Lucy Meriwether,  of English ancestry. After his father died of pneumonia in November 1779, he moved with his mother and stepfather Captain John Marks to Georgia.  They settled along the Broad River in the Goosepond Community within the Broad River Valley in Wilkes County (now Oglethorpe County).
Lewis had no formal education until he was 13 years of age, but during his time in Georgia he enhanced his skills as a hunter and outdoorsman. He would often venture out in the middle of the night in the dead of winter with only his dog to go hunting. Even at an early age, he was interested in natural history, which would develop into a lifelong passion. His mother taught him how to gather wild herbs for medicinal purposes.
In the Broad River Valley, Lewis first dealt with American Indians. This was the traditional territory of the Cherokee, who resented encroachment by the colonists. Lewis seems to have been a champion for them among his own people. While in Georgia, he met Eric Parker, who encouraged him to travel. At age 13, Lewis was sent back to Virginia for education by private tutors. His father's older brother Nicholas Lewis became his guardian.  One of his tutors was Parson Matthew Maury, an uncle of Matthew Fontaine Maury. In 1793, Lewis graduated from Liberty Hall (now Washington and Lee University).
That year he joined the Virginia militia, and in 1794 he was sent as part of a detachment involved in putting down the Whiskey Rebellion. In 1795, Lewis joined the United States Army, commissioned as an ensign—an army rank that was later abolished and was equivalent to a modern-day second lieutenant. By 1800 he rose to captain, and ended his service there in 1801. Among his commanding officers was William Clark, who would later become his companion in the Corps of Discovery.
On April 1, 1801, Lewis was appointed as Secretary to the President by President Thomas Jefferson, whom he knew through Virginia society in Albemarle County. Lewis resided in the presidential mansion, and frequently conversed with various prominent figures in politics, the arts and other circles.  He compiled information on the personnel and politics of the United States Army, which had seen an influx of Federalist officers as a result of " midnight appointments" made by outgoing president John Adams in 1801. 
When Jefferson began to plan for an expedition across the continent, he chose Lewis to lead the expedition. Meriwether Lewis recruited Clark, then aged 33, to share command of the expedition.[ citation needed]
After the Louisiana Purchase in 1803, Thomas Jefferson wanted to get an accurate sense of the new land and its resources. The President also hoped to find a "direct and practicable water communication across this continent, for the purposes of commerce with Asia."  In addition, Jefferson placed special importance on declaring U.S. sovereignty over the Native Americans along the Missouri River.    
The two-year exploration by Lewis and Clark was the first transcontinental expedition to the Pacific Coast by the United States; however, Lewis and Clark reached the Pacific 12 years after Sir Alexander Mackenzie had done so overland in Canada.  When they left Fort Mandan in April 1805 they were accompanied by the 16-year-old Shoshone Indian woman, Sacagawea, the wife of the French-Canadian fur trader, Toussaint Charbonneau. The Corps of Discovery made contact with many Native Americans in the trans-Mississippi West and found them accustomed to dealing with European traders and already connected to global markets.
After crossing the Rocky Mountains, the expedition reached the Oregon Country (which was disputed land beyond the Louisiana Purchase) and the Pacific Ocean in November 1805. They returned in 1806, bringing with them an immense amount of information about the region as well as numerous plant and animal specimens.  They demonstrated the possibility of overland travel to the Pacific coast. The success of their journey helped to strengthen the American concept of " Manifest destiny" – the idea that the United States was destined to reach all the way across North America from Atlantic to Pacific.  
After returning from the expedition, Lewis received a reward of 1,600 acres (6.5 km2) of land. He also initially made arrangements to publish the Corps of Discovery journals, but had difficulty completing his writing. In 1807, Jefferson appointed him governor of the Louisiana Territory; he settled in St. Louis.
Lewis' record as an administrator is mixed. He published the first laws in the Upper-Louisiana Territory, established roads and furthered Jefferson's mission as a strong proponent of the fur trade. He negotiated peace among several quarreling Indian tribes. His duty to enforce Indian treaties was to protect the western Indian lands from encroachment,  which was opposed by the rush of settlers looking to open new lands for settlements. But due to his quarreling with local political leaders, controversy over his approvals of trading licenses, land grant politics, and Indian depredations, some historians have argued that Lewis was a poor administrator.
That view has been reconsidered in recent biographies. Lewis's primary quarrels were with his territorial secretary Frederick Bates. Bates was accused of undermining Lewis to seek Lewis's dismissal and his own appointment as governor. Because of the slow-moving mail system, former president Jefferson and Lewis's superiors in Washington got the impression that Lewis did not adequately keep in touch with them. 
Bates wrote letters to Lewis's superiors accusing Lewis of profiting from a mission to return a Mandan chief to his tribe. Because of Bates' accusation, the War Department refused to reimburse Lewis for a large sum he personally advanced for the mission. When Lewis's creditors heard that Lewis would not be reimbursed for the expenses, they called Lewis's notes, forcing him to liquidate his assets, including land he was granted for the Lewis and Clark Expedition. One of the primary reasons Lewis set out for Washington on this final trip was to clear up questions raised by Bates and to seek a reimbursement of the money he had advanced for the territorial government.
The U.S. government finally reimbursed the expenses to Lewis's estate two years after his death. Bates eventually became governor of Missouri. Though some historians have speculated that Lewis abused alcohol or opiates based upon an account attributed to Gilbert Russell at Fort Pickering on Lewis's final journey,  others have argued that Bates never alleged that Lewis suffered from such addictions and that Bates certainly would have used them against Lewis if Lewis suffered from those conditions.
Lewis was a Freemason, initiated, passed and raised in the "Door To Virtue Lodge No. 44" in Albemarle, Virginia, between 1796 and 1797.  On August 2, 1808, Lewis and several of his acquaintances submitted a petition to the Grand Lodge of Pennsylvania requesting dispensation to establish a lodge in St. Louis. Lewis was nominated and recommended to serve as the first Master of the proposed Lodge, which was warranted as Lodge No. 111 on September 16, 1808.  (See List of Notable Freemasons)
Unlike William Clark, who brought his slave York on the westward expedition, Lewis did not have a personal valet slave. Although Lewis attempted to supervise enslaved people while running his mother's plantation before the expedition, he left that post and had no valet during the expedition. Lewis made assignments to York but allowed Clark to supervise him; Lewis also granted York and Sacagewea votes during expedition meetings. Later, Lewis hired a free African-American man as his valet, John Pernia. Pernia accompanied Lewis during his final journey, although his wages were considerably in arrears. After Lewis' death, Pernia continued to Monticello and asked Jefferson to pay the $240 owed him, but was refused. Pernia later committed suicide. 
On September 3, 1809, Lewis set out for Washington, D.C. He hoped to resolve issues regarding the denied payment of drafts he had drawn against the War Department while serving as governor of the Upper Louisiana Territory, leaving him in potentially ruinous debt. Lewis carried his journals with him for delivery to his publisher. He intended to travel to Washington by ship from New Orleans, but changed his plans while floating down the Mississippi River from St. Louis. He disembarked and decided instead to make an overland journey via the Natchez Trace and then east to Washington. (The Natchez Trace was the old pioneer road between Natchez, Mississippi, and Nashville, Tennessee.) Robbers preyed on travelers on that road and sometimes killed their victims.  Lewis had written his will before his journey and also attempted suicide on this journey, but was restrained.

According to a lost letter from October 19, 1809, to Thomas Jefferson, Lewis stopped at an inn on the Natchez Trace called Grinder's Stand, about 70 miles (110 km) southwest of Nashville on October 10. After dinner, he retired to his one-room cabin. In the predawn hours of October 11, the innkeeper's wife ( Priscilla Grinder) heard gunshots. Servants found Lewis badly injured from multiple gunshot wounds, one each to the head and gut. He bled out on his buffalo hide robe and died shortly after sunrise. The Nashville Democratic Clarion published the account, which newspapers across the country repeated and embellished. The Nashville newspaper also reported that Lewis's throat was cut.  Money that Lewis had borrowed from Major Gilbert Russell at Fort Pickering to complete the journey was missing.
While Lewis's friend Thomas Jefferson and some modern historians have generally accepted Lewis's death as a suicide, debate continues, as discussed below. No one reported seeing Lewis shoot himself. Three inconsistent somewhat contemporary accounts are attributed to Mrs. Grinder, who left no written account or testimony—some thus believe her testimony was fabricated, while others point to it as proof of suicide.  Mrs. Grinder claimed Lewis acted strangely the night before his death: standing and pacing during dinner and talking to himself in the way one would speak to a lawyer, with face flushed as if it had come on him in a fit. She continued to hear him talking to himself after he retired, and then at some point in the night, she heard multiple gunshots, a scuffle, and someone calling for help.
She claimed to be able to see Lewis through the slit in the door crawling back to his room. However, she never explained why she never investigated further at the time, but only the next morning sent her children to look for Lewis's servants. Another account claimed the servants found Lewis in the cabin, wounded and bloody, with part of his skull gone, but he lived for several hours. In the last account attributed to Mrs. Grinder, three men followed Lewis up the Natchez Trace, and he pulled his pistols and challenged them to a duel. In that account, Mrs. Grinder said that she heard voices and gunfire in Lewis's cabin about 1:00 am. She found the cabin empty and a large amount of gunpowder on the floor. Thus, in this account, Lewis's body was found outside the cabin.
Lewis's mother and relatives always contended it was murder. A coroner's jury held an inquest immediately after Lewis's death as provided by local law; however, they did not charge anyone with murdering Lewis.  The jury foreman kept a pocket diary of the proceedings, which disappeared in the early 1900s.[ citation needed] When William Clark and Thomas Jefferson were informed of Lewis's death, both accepted the conclusion of suicide. Based on their positions and the never-found Lewis letter of mid-September 1809, historian Stephen Ambrose dismissed the murder theory as "not convincing". 
The only doctor to examine Lewis's body did not do so until 40 years later, in 1848.  The Tennessee State Commission, including Dr. Samuel B. Moore, charged with locating Lewis's grave and erecting a monument over it, opened Lewis's grave. The commission wrote in its official report that though the impression had long prevailed that Lewis died by his own hand, "it seems to be more probable that he died by the hands of an assassin."  In the book The History of the Lewis and Clark Expedition, first printed in 1893, the editor Elliott Coues expressed doubt about Thomas Jefferson's conclusion that Lewis committed suicide, despite including the former president's Memoir of Meriwether Lewis in his book. 
From 1993–2010, about 200 of Lewis's kin (through his sister Jane, as he had no children) sought to have the body exhumed for forensic analysis, to try to determine whether his death was a suicide or murder. A Tennessee coroner's jury in 1996 recommended exhumation. However, since Lewis's gravesite is in a national monument, the National Park Service must approve. The agency refused the request in 1998, citing possible disturbance to the bodies of more than 100 pioneers buried nearby. In 2008, the Department of the Interior approved the exhumation, but rescinded that decision in 2010, stating that decision is final.[ citation needed] It is nonetheless improving the grave site and visitor facility. 
Historian Paul Russell Cutright wrote a detailed rebuttal of the murder robbery theory, concluding that it "lacks legs to stand on".   He stressed Lewis's debts, heavy drinking, possible morphine and opium use, failure to prepare the expedition's journals for publication, repeated failure to find a wife, and the deterioration of his friendship with Thomas Jefferson.   This refutation was countered by Dr. Eldon G. Chuinard, (physician), who argued for the murder hypothesis on the basis that Lewis's reported wounds were inconsistent with his reported two hour survival after the shooting. This theory has been challenged by Dr. David J. Peck (physician), with support from Forensic Pathology and Trauma Surgery. Leading Lewis scholars Donald Jackson, Jay H. Buckley, Clay S. Jenkinson and others, have stated that, regardless of their leanings or beliefs, the facts of his death are not known, there are no eyewitnesses, and the reliability of reports of those in the place or vicinity cannot be considered certain. Author Peter Stark believes that post-traumatic stress disorder may have been a contributor to Meriwether Lewis's condition after spending months traversing hostile Indian territory, particularly because travelers coming afterward exhibited the same symptoms. 
The explorer was buried near present-day Hohenwald, Tennessee, near his place of death. His grave was located about 200 yards from Grinder's Stand, alongside the Natchez Trace. (That section of the 1801 Natchez Trace was built by the U.S. Army under the direction of Lewis' mentor Thomas Jefferson, during Lewis' lifetime).
At first, the grave was unmarked. Alexander Wilson, an ornithologist and friend of Lewis' who visited the grave in May 1810, during a trip to New Orleans to sell his drawings, wrote that he gave the innkeeper Robert Griner money to erect a fence around the grave to protect it from animals. 
The State of Tennessee erected a monument over Lewis' grave in 1848. Lemuel Kirby, a stonemason from Columbia, Tennessee, chose the design of a broken column, commonly used at the time to symbolize a life cut short. 
An iron fence erected around the base of the monument was partially dismantled during the Civil War by General Hood's detachments marching from Shiloh toward Franklin; they forged the iron into horseshoes 
A September 1905 article in Everybody's Magazine called attention to Lewis' abandoned and overgrown grave.  A county road worker, Teen Cothran, took the initiative to open a road to the cemetery. Thereafter, a local Tennessee Meriwether Lewis Monument Committee was soon formed to push for restoring Lewis' gravesite. In 1925, in response to the committee's work, President Calvin Coolidge designated Lewis' grave as the fifth National Monument in the South.
In 2009, the Lewis and Clark Trail Heritage Foundation organized a commemoration for Lewis in conjunction with their 41st annual meeting October 3–7, 2009.  It included the first national memorial service at his grave site. On October 7, 2009, near the 200th anniversary of Lewis' death, about 2,500 people (National Park Service estimate) from more than 25 states gathered at his grave to acknowledge Lewis' life and achievements. Speakers included William Clark's descendant Peyton "Bud" Clark, Lewis' collateral descendants Howell Bowen and Tom McSwain, and Stephanie Ambrose Tubbs ( Stephen Ambrose's daughter; her father wrote Undaunted Courage, an award-winning book about the Lewis and Clark Expedition). A bronze bust of Lewis was dedicated at the Natchez Trace Parkway for a planned visitor center at the grave site area. The District of Columbia and governors of 20 states associated with the Lewis and Clark Trail sent flags flown over state capital buildings to be carried to Lewis' grave by residents of the states, acknowledging the significance of Lewis' contribution in the creation of their states. 
The 2009 ceremony at Lewis' grave was the final bicentennial event honoring the Lewis and Clark Expedition. Re-enactors from the Lewis and Clark Bicentennial participated, and official attendees included representatives from Jefferson's Monticello. Lewis and Clark descendants and family members, along with representatives of St. Louis Lodge #1, past presidents of the Lewis and Clark Trail Heritage Foundation, and the Daughters of the American Revolution, carried wreaths and led a formal procession to Lewis' grave. Samples of plants which Lewis discovered on the expedition were brought from the Trail states and laid on his grave. The U.S. Army was represented by the 101st Airborne Infantry Band and its Army chaplain. The National Park Service announced that it would rehabilitate the site.

For many years, Lewis' legacy was overlooked, inaccurately assessed, and somewhat tarnished by his alleged suicide.  Yet his contributions to science, the exploration of the Western U.S., and the lore of great world explorers, are considered incalculable. 
Four years after Lewis' death, Thomas Jefferson wrote:
"Of courage undaunted, possessing a firmness & perseverance of purpose which nothing but impossibilities could divert from it's direction, careful as a father of those committed to his charge, yet steady in the maintenance of order & discipline, intimate with the Indian character, customs & principles, habituated to the hunting life, guarded by exact observation of the vegetables & animals of his own country, against losing time in the description of objects already possessed, honest, disinterested, liberal, of sound understanding and a fidelity to truth so scrupulous that whatever he should report would be as certain as if seen by ourselves, with all these qualifications as if selected and implanted by nature in one body, for this express purpose, I could have no hesitation in confiding the enterprise to him. 
Jefferson wrote that Lewis had a "luminous and discriminating intellect." William Clark's first son Meriwether Lewis Clark was named after Lewis; the senior Meriwether Clark passed the name on to his son, Meriwether Lewis Clark, Jr.
Captain Meriwether Lewis and Lieutenant (de facto Co-Captain and posthumously, officially promoted to Captain in advance of the bicentennial) William Clark commanded the Corps of Discovery to map the course of the Missouri River to its source and the Pacific Northwest overland and water routes to and from the mouth of the Columbia River. They were honored with a 3-cent stamp July 24, 1954 on the 150th anniversary. The 1803 Louisiana Purchase doubled the size of the United States. Lewis and Clark described and sketched its flora and fauna and described the native inhabitants they encountered before returning to St. Louis in 1806. 
Both Lewis and Clark appear on the gold Lewis and Clark Exposition dollars minted for the Lewis and Clark Centennial Exposition. Among the Early United States commemorative coins, they were produced in both 1904 and 1905 and survive in relatively small numbers.
The Lewis and Clark Expedition was celebrated on May 14, 2004, the 200th anniversary of its outset, by depicting the two on a hilltop outlook: two companion 37-cent USPS stamps showed portraits of Meriwether Lewis and William Clark. A special 32-page booklet accompanied the issue in eleven cities along the route taken by the Corps of Discovery. An image of the stamp can be found on Arago online at the link in the footnote. 
The plant genus Lewisia (family Portulacaceae), popular in rock gardens and which includes the bitterroot ( Lewisia rediviva), the state flower of Montana, is named after Lewis, as is Lewis's woodpecker (Melanerpes lewis) and a subspecies of cutthroat trout, the westslope cutthroat (Oncorhynchus clarki lewisi).
