8 Explorers Who Mysteriously Disappeared (and Some Who’ve Been Found)

By their very nature, explorers often push the boundaries of survival in the name of glory, so it’s not a great surprise that many have gone missing in the course of their adventures. Over the years, the quest to uncover the truth of what happened to them has captivated the public, historians, and journalists alike, leading to numerous theories and some surprising finds.

1. Gaspar and Miguel Corte-Real

The youngest of three Portuguese brothers, Gaspar Corte-Real was a keen explorer who undertook an expedition to Greenland in 1500. He embarked on a second expedition in 1501 with his older brother Miguel, in which they claimed Greenland for the crown before apparently sailing on to reach Newfoundland or Labrador. At that point, Gaspar sent two of his three ships back to Portugal, including the one captained by his brother. Gaspar’s ship continued its explorations, but was never seen again.

In 1502, Miguel Corte-Real, learning of his brother’s disappearance, led a search party to the area where Gaspar was believed lost, but he found nothing, and his ship too went missing. The oldest Corte-Real brother, Vasco Annes, begged the king to let him mount a further search party to find his lost brothers, but the king refused—perhaps unwilling to risk the embarrassment of losing a third Corte-Real.

The disappearances have remained a mystery for centuries. But in the 1910s, Edmund Burke Delabarre, a psychology professor at Brown University, put forward a new theory about the inscriptions on the famous Dighton Rock in Massachusetts. The rock is covered with petroglyphs that were first noted way back in 1680, and since then scholars have proposed numerous theories about who carved them and why. Delabarre suggested that the inscription was in fact abbreviated Latin, and reads: “I, Miguel Cortereal, 1511. In this place, by the will of God, I became a chief of the Indians.” This astounding theory implies that the explorer may have continued his travels into America and survived at least nine years in the New World. If his inscription is to be believed, he made quite a success of his new life.

2. Jean-Francois De Galaup

Jean-Francois de Galaup, Comte de la Pérouse, was an accomplished sea captain. In 1785, inspired by the successes of Captain James Cook, the French king Louis XVI sent La Pérouse on an expedition to explore the Pacific. The party was made up of two ships—La Boussole and L'Astrolabe—manned by 225 crewmembers. The voyage was expected to last four years. La Pérouse kept scrupulous records of his findings during the trip, mapping coastlines, taking specimens, and making observations of the peoples and places he encountered. (Thankfully, he sent his journals back to France, where they were preserved for posterity and later published to great success.) Having successfully sailed through the Pacific, taking in Japan, the Philippines, and Tonga, La Pérouse arrived at Botany Bay in Australia and was witnessed by British settlers sailing out of the bay in March 1788, the last sighting of the expedition. By 1791, when no communication had been received from La Pérouse for some time, a search party was dispatched from France—but no trace of the expedition was found.

The puzzle seemed to be solved in 1826 when an Irish sailor, Peter Dillon, came across something intriguing while exploring the Solomon Islands. The locals had a number of European swords, which Dillon thought might have belonged to La Pérouse, and told of sighting two large ships that had broken up on the reefs there. In 1964 the wreck of La Boussole was at last discovered on the reefs of Vanikoro in the Solomon Islands, confirming that this indeed was where the expedition had reached its sad end. However, in 2017 an Australian researcher found an 1818 account by an Indian castaway that seems to suggest La Pérouse was killed by locals on a small island off Northern Australia, perhaps in a later leg of his voyage after constructing a schooner from the remains of La Boussole.

3. Naomi Uemura

Modern explorer and adventurer Naomi Uemura was part of the first Japanese team to scale Mount Everest in 1970. (He would have been the first Japanese person to reach the summit if his impeccable manners hadn’t made him relinquish the lead to allow his elder, Teruo Matsuura, the honor of going first.) Uemura completed many amazing feats during his lifetime, including climbing the highest mountain on each of the world’s continents solo, trekking across the Arctic to become the first person to reach the North Pole solo, and rafting down the Amazon. In February 1984, Uemura set off to scale Mount McKinley in Alaska in an attempt to become the first person to achieve a solo winter climb of the treacherous peak. Uemura reached the peak, but that is all we know, as he never made it off the mountain. Rescue parties searched for the adventurer, but all that was found was some equipment and his diary hidden in a snow cave. To date his body has not been found, and the exact circumstances of his tragic death remain a mystery.

4. Percy Fawcett

In the last 90 years, some 13 expeditions and over 100 people have perished in futile attempts to discover the fate of British explorer Colonel Percy Harrison Fawcett. Fawcett was the very epitome of a dashing explorer: He had a distinguished military career before following his sense of adventure to help create maps of the vast and uncharted Amazon jungle. During the 1920s, he departed on a number of ambitious expeditions in an attempt to locate the fabled lost city of El Dorado, which he dubbed the city of “Z.”

In 1925 Fawcett set off into the Mato Grosso region of Brazil with his eldest son, Jack, and his son’s best friend, Raleigh Rimell. The trio plowed into the jungle, covering up to 15 miles in a day in their zeal to find the rumored riches of the lost city. By May 29 the group sent their native guides back with their latest letters, including one to Fawcett’s wife, Nina, in which he wrote: “You need have no fear of any failure.” This missive was the last thing heard of Fawcett, and after two years with no sign, the Royal Geographical Society sent the first of many search parties. That no trace was discovered of Fawcett only served to keep the many rumors surrounding his fate alive.

Researchers have since come forward with many different theories: Fawcett had “gone native” and was living among a remote tribe; he succumbed to malaria or a jaguar attack; he deliberately disappeared in order to set up a mystical commune. But perhaps the most believable version of his fate was obtained by journalist David Grann, who retraced Fawcett’s steps in 2005 and discovered the Kalapalo Indians had an oral history indicating that Fawcett had ignored their advice and walked right into the domain of a hostile tribe who, in all likelihood, killed him.

5. George Bass

George Bass was an English surgeon who, inspired by tales of Pacific exploration, took to the seas as a ship’s surgeon. He embarked on many expeditions, but the one for which he is most remembered is his voyage to Australia with Matthew Flinders in the 1790s. The pair mapped large swathes of the Australian coast, and Bass identified the body of water between Australia and Tasmania that was later named the Bass Strait in his honor. Despite his success as an explorer, Bass felt under-appreciated and became envious of the merchants who were making their fortunes shipping goods from Europe to the new settlements in Australia. Consequently, he abandoned his cartography and set himself up as a trader. Unfortunately he was a little late to the party and when he returned to Australia, his ship laden with goods, he discovered many others had beaten him to the punch and the market was saturated with British products.

Undeterred, he decided to try his luck in South America and set sail with his bounteous cargo in 1803. Bass and his ship were never seen again, and their fate remains an enigma. Rumors persisted that Bass made it to Chile or Peru, where he was captured by the Spaniards and forced to work in the mines there as a slave until his death.

6. George Mallory

George Mallory was a British explorer and mountaineer who captured the public’s imagination after he was asked why he wanted to climb Everest and he responded: “Because it’s there.” As one of the foremost mountaineers of his day, Mallory was an obvious choice to take part in the first British expeditions to the as-yet-unconquered Everest throughout the early 1920s—well before the benefit of modern materials, technology, and weather forecasting.

In June 1924, George Mallory and fellow mountaineer Andrew Irvine set off for an attempt on the summit. Another member of the expedition glimpsed them climbing at over 26,800 feet, but that was the last time they were seen alive. That the pair perished in their attempt was certain, but debate raged over whether they had become the first to reach the summit and died on their way down, or if they died having never reached the top. Various pieces of the puzzle emerged over time—in the 1930s, Irvine’s ice axe was discovered at 27,700 feet, and in 1991 a 1920s oxygen canister was found. Finally, in 1999, an expedition discovered Mallory’s frozen body on the mountainside, clearly the victim of a terrible fall. The climbers carefully buried the body where they found it, but sadly no trace was ever found of Andrew Irvine.

It was hoped that Mallory’s camera might be found—an artifact that could prove for certain if he made it to the summit—but unfortunately the camera remains missing. Tantalizingly, Mallory had stated that he was going to carry a photograph of his wife and leave it at the summit, and when Mallory’s body was found the photograph was not there, providing yet another clue that perhaps this great mountaineer had conquered the world’s tallest mountain.

7. Sir John Franklin

One of the foremost explorers of the Victorian era was Sir John Franklin, who had captained a number of expeditions to the Arctic in search of the Northwest passage. Franklin succeeded in mapping large areas of coastline, identifying many new botanical specimens and furthering our knowledge of the unforgiving Arctic weather during his first two expeditions. Some 20 years after he had retired, Franklin was tempted back to make one final effort to find the Northwest Passage. In 1845, when Franklin was 60 years old, he set off with 129 crewmembers in HMS Erebus and HMS Terror. The ships made it to Baffin Island, where they were sighted by a whaling ship, but after that the ships were seen no more.

With no word from the expedition, numerous rescue missions were sent out to try and discover their fate. Finally, in 1859, after a tip-off from local Inuit hunters, a team led by Francis McClintock found objects and remains from the group on King William Island. It became clear that the two ships had become hopelessly trapped in the sea ice. A note was found which indicated that the ships had finally been abandoned in April 1848, having been stuck fast in the ice since September 1846. The note also revealed that Franklin had died in June 1847, though no cause was given. Scientific analysis of the mummified remains of some of the sailors indicated they may have died from lead poisoning, likely caused by the lead used to seal their canned food. Historians argue that those who did not die from contaminated supplies probably perished in the freezing conditions as they tried to march across the ice to safety. In September 2016, archaeologists announced the discovery of the wrecked remains of HMS Terror off the coast of King William Island, which historians hope will provide yet more clues about the terrible fate of the stranded crew and their desperate struggle for survival.

8. Ludwig Leichhardt

In 1848, German scientist and explorer Ludwig Leichhardt led an attempt to cross Australia’s desert interior from east to west. Leichhardt was already an explorer of some renown, having completed two earlier expeditions across Australia—on one occasion, he had been given up for dead after he spent 18 months in the Australian interior, only to show up very much alive and with copious notes and discoveries.

Leichhardt set off for his final mission accompanied by seven companions, 50 bullocks, 20 mules, seven horses, and a huge amount of supplies and equipment. Despite all of that, the only trace ever found of the missing expedition was a small brass plaque inscribed with Leichhardt’s name and the year 1848, which had been attached to his rifle. The lack of any further evidence of the bodies or equipment from the expedition has proved an enduring mystery, and things aren’t made any clearer by the fact that no one is sure which route they took or how far through Australia’s vast interior they got.

An 1852 search party reported that they had found an abandoned campsite with a tree with the letter L carved into it, a mark Leichhardt reportedly frequently left to indicate his route. Over the years a number of further searches uncovered more trees inscribed with an L, but their disparate locations did little to solve the riddle of the progress and fate of the explorers. The public was so intrigued by the mysterious disappearance that numerous rumors were published in the newspapers, inevitably leading to sensationalist stories of the group dying of thirst, being murdered by Aboriginal people, or even of Leichhardt surviving into old age living in the bush. However, until some concrete evidence or remains are discovered, it is likely that the truth will remain elusive.

The Cleveland Torso Murderer: The Scariest Serial Killer You've Never Heard Of

Kutsuks/iStock via Getty Images

Even in the throes of the Great Depression, there was a lot going on in Cleveland in 1936. Then the sixth-biggest city in the United States, Cleveland had sold itself as the “city of conventions,” welcoming travelers to downtown through its new union train station, with a variety of fancy hotels nearby and a state-of-the-art public auditorium.

For the second time in a dozen years, the city hosted the Republican National Convention, but the big event in Ohio that summer—and the summer after—was the Great Lakes Exposition, celebrating Cleveland’s centennial. The fair, which spread across 135 acres through downtown Cleveland and on the Lake Erie shore, touted local businesses like Higbee’s Department Store, Standard Oil (John D. Rockefeller had founded the company in 1870 in Cleveland), and General Electric, which was showing off its new fluorescent lights. It also spotlighted the handiwork of a serial killer who had been plying his trade for nearly a year.

Killer Attraction

On June 5, 1936, two boys who had cut school to go fishing found a rumpled pair of pants under a tree on the city’s east side. Tied up in the pants was a man’s severed head. The nude, exsanguinated body was found by nearby railroad tracks soon after. The cause of death was decapitation. It was the fourth dismembered body to show up in less than a year, and Cleveland police realized they had a serial killer on their hands.

A plaster cast of the man’s face and a diagram showing all the tattoos on his body were displayed at the Great Lakes Exposition. More than 11 million people attended the exposition in the two summers it was open, but none could identify “the tattooed man,” one of at least a dozen “torso murders” that plagued northern Ohio—and possibly beyond.

The killer became known as the Mad Butcher of Kingsbury Run, since most of the bodies were found in that area, described by Cleveland News reporter Frank Otwell as “an unwholesome, crooked gash that meanders carelessly through Cleveland’s lower east side.” The crime bedeviled investigators, including Eliot Ness, one of the era’s most celebrated lawmen.

More than 1500 people were questioned in connection with the murders. A shantytown was burned. Ness’s career ended up ruined. And the case remains officially unsolved to this day.

Untouchable Indeed

When Eliot Ness arrived in Cleveland in 1934, he was known as one of the treasury agents who helped enforce Prohibition laws and did battle with gangsters in Chicago, including Al Capone. Because of his “untouchable” reputation, Ness was named public safety director for the city the following year. His mission was to professionalize and revitalize a police department that had become a corrupt, lazy unit of political patronage.

By the time Ness took office, the Mad Butcher had already claimed four victims. The first two were found in September 1935, both decapitated, exsanguinated, and washed; their genitals had been cut off as well. One was never identified. The other was Edward Andrassy. A year earlier, the lower half of a woman’s torso, down to the knees, had washed ashore east of Cleveland. “The Lady of the Lake” was later determined to be the Mad Butcher’s first victim.

Body parts continued to pile up. Lead police investigator Peter Merylo noted similarities between the Torso Murders and other dismemberment killings in western Pennsylvania, theorizing that the killer might be hopping trains and hiding bodies in boxcars (Kingsbury Run and the city of Cleveland had plenty of railroad tracks). Cuyahoga County coroner Dr. Samuel Gerber said the precision with which the bodies had been dismembered led him to believe the killer could have had some medical training.

Ultimately, Ness was drawn to Francis Sweeney, a doctor from a prominent Cleveland family (his first cousin, Martin Sweeney, was a congressman). Residents were terrified, and public pressure began to mount on Ness, who ultimately holed Sweeney up in a downtown hotel and questioned him for weeks, including with a polygraph. Ness felt Sweeney was the murderer, but could never bring it to trial. For years afterward, Ness would receive taunting postcards from Sweeney.

"Rest Easy Now"

The killer was known as the Mad Butcher, but the killings themselves drove Ness mad. Two more bodies—officially, the 11th and 12th victims—were discovered on August 16, 1938, in a spot on the lakefront that could be seen from Ness’s office. Two days later, Cleveland police swept through Kingsbury Run making dozens of arrests and burning down the shantytowns. Ness was excoriated for his actions—but the murders stopped.

In late 1938, the Cleveland police received a letter purportedly from the killer. “You can rest easy now,” it read. “I have come out to sunny California for the winter.” The killer claimed to have killed someone and buried their body on Century Boulevard between Crenshaw and Western in Los Angeles. No body was ever found.

Ultimately, the only person ever arrested for the Torso Murders was Frank Dolezal, a bricklayer who had lived with Flo Polillo, the third victim, and knew Andrassy and Rose Wallace, the only other victims who were ever identified. Dolezal confessed to killing Polillo, but later recanted. He died in custody, officially a suicide, but his death remains suspicious.

In 1947—the same year Ness unsuccessfully ran for mayor of Cleveland—a woman, later identified as Elizabeth Short, was found murdered in Leimert Park in Los Angeles. Short was cut in half, her intestines were removed, and she was drained of her blood—all similar hallmarks to the Torso Murders. She became known as the Black Dahlia, and her murder has one more thing in common with the Torso Murders: It remains unsolved.

Ness died at 54 in 1957, broke and broken; the man who was once the nation’s top Prohibition agent now had a serious drinking problem of his own. Six months after his death, his memoir, The Untouchables, was published and became the basis for a television show a year later. Ness has remained a pop culture icon ever since. Forty years after his death, Ness was given a funeral with full police honors in Cleveland, and his ashes were scattered at Lake View Cemetery on the city’s east side—not far from Kingsbury Run, where the Mad Butcher left a trail of body parts.
