Everest, Kosciuszko, Cook, Logan: many of the world's mountains carry a person's name. I linked 2,228 peaks, ranges and hills named after people to the places those people were born. Click a mountain and follow the line home.
The highest mountain on Earth is named after a man who never saw it. George Everest, the Surveyor General of India, was born in Wales or England (the records disagree) and retired before his successor, Andrew Waugh, proposed his name for Peak XV in 1856; the Royal Geographical Society adopted it in 1865. Across the world, surveyors, explorers and colonial officials put the names of their bosses, patrons, monarchs and colleagues on mountains that already had names in the languages of the people who lived beneath them. Some of those names have since been given back.
Wikidata, the open database behind Wikipedia, records what many mountains are named after and where most of those people were born. I joined the two for every mountain, summit, hill, volcano and range named after a person: 2,228 features, 2,241 namings and 2,010 people, 1,635 of them with a birthplace I could map. The question is the one I asked of the Moon. Whose world is it, on the map?
Each triangle is a mountain named after a person, coloured by the continent where that person was born. Click one to draw the line home; click a birthplace to see every mountain named after the people born there. Filter by where the mountain is, or by what the person did.
Triangles: mountains, coloured by the continent of birth of the person they honour (grey: birthplace not known). Circles: birthplaces, sized by the number of mountains. Lines: great circles from each mountain to its namesake's birthplace (on by default when a filter is chosen, and for the selected mountain). Base map: the Inked World style on OpenStreetMap data via OpenFreeMap.
In Europe the mountains are named after Europeans: 98% of European peaks named after a person honour someone born in Europe. Everywhere else, the names came with surveyors from far away. In Australia and New Zealand 84% honour someone born on another continent, 79% in Europe; in South America 71%; in North America 35%. Of New Zealand's person-named peaks with a mapped namesake, 88% honour someone born outside New Zealand, most of them in the United Kingdom; for Australia it is 84%. The typical line from a peak outside Europe and Antarctica to its namesake's birthplace is 3,289 km long, and the longest run from New Zealand to Britain and Portugal, almost to the other side of the globe: Mount Grey honours George Grey, Governor of New Zealand, born in Lisbon.
Where the honoured were born, by where the mountain is
Mountains named after a person with a mapped birthplace, by the continent of the mountain (rows) and of the birthplace (colours). Hover a block.
Four in five of the person-named peaks of Australia and New Zealand honour someone born on another continent.
Antarctica is the extreme case. Nobody is born there, so all 621 of its person-named features with a mapped namesake honour someone from elsewhere: 73% born in Europe and 16% in North America. And on Svalbard, where Norway has held sovereignty since 1925 after centuries of mostly foreign exploration, 73% of the person-named mountains honour people born outside Norway, above all Swedish, German and British scientists.
Putting each person in one group (titles of rule first, then specific professions, then politics, then the rest), 29% of the people on the mountains were scientists and 19% royals, rulers or politicians, the largest group in North America and in Australia and New Zealand; 17% were explorers, mountaineers or aviators, 12% military or naval officers and 11% surveyors, geographers or cartographers. The surveyors named peaks after one another and after their superiors: the Surveyor General of India got the highest mountain on Earth, and the California Geological Survey of the 1860s put its leader Josiah Whitney, its members William Brewer and Charles Hoffmann and the geologist James Dwight Dana on the peaks of the High Sierra. The most honoured person in the data is the botanist Ferdinand von Mueller, with 6 features.

The tallest mountains named after people in Wikidata are Everest (8,849 m), Ismoil Somoni Peak (7,495 m), the highest point of Tajikistan, named after the Samanid ruler of the ninth century, and Lenin Peak (7,134 m) on the Kyrgyz and Tajik border. The Soviet Pamirs are full of revolutionaries and scientists. In North America the tallest is Denali, named Mount McKinley after the American president in federal use from 1917, renamed Denali in 2015 and Mount McKinley again by presidential order in 2025; the State of Alaska, which adopted Denali in 1975, still calls it Denali.
The fifteen highest
Elevations as Wikidata gives them; where a value is higher than the country's highest point it is read as feet and converted. Click a row.
Of the 2,224 namings whose person has a recorded sex, 113 honour a woman (5.1%). Queens and princesses are a large part of them (30%), from Mount Victoria to the Queen Maud Mountains, but so are scientists such as the astronomer Beatrice Tinsley and the botanist Nancy Burbidge, mountaineers such as Fay Fuller, and the aviators Amelia Earhart and Jean Batten. Among people born since 1900, 11.5% are women, against 3.9% of those born earlier.
Some of these names are being taken off the map. Wikidata records official renamings of person-named peaks: Mount McKinley became Denali in 2015 (and Mount McKinley again for the US federal government in 2025, though Alaska keeps Denali), Harney Peak in South Dakota became Black Elk Peak in 2016, Jeff Davis Peak in Nevada became Doso Doyabi in 2019, Mount Evans in Colorado became Mount Blue Sky in 2023, and Clingmans Dome in the Smoky Mountains became Kuwohi in 2024. Earlier, Mount Stalin in Canada became Mount Peck in 1987 and the Lenin Hills in Moscow went back to being the Sparrow Hills; Western Australia's King Leopold Ranges became the Wunaamin-Miliwundi Ranges in 2020. In New Zealand and Australia a gentler route is the dual name: Ōrongomai / Cass Peak, Takarunga / Mount Victoria, Ōwairaka / Mount Albert, Kunanyi / Mount Wellington, Kata Tjuta / Mount Olga, Mount MacKenzie / Pakihiwitahi, Aoraki / Mount Cook, Mount Grey / Maukatere and Mount Herbert / Te Ahu Pātiki. In 2022 the United States also replaced a slur for Native American women in the names of nearly 650 places; Wikidata records 96 of them that are hills, peaks or mountains.
Renamed mountains
From Wikidata's dated official names and its "named after" links to former names.
Data. Everything comes from Wikidata (CC0), queried through QLever: every mountain, summit, hill, volcano or range that is "named after" (P138) a human, with its coordinates, elevation and country, and the person's birthplace and its coordinates, date of birth, sex and occupations. I removed the duplicate rows the query makes for every occupation and type, left out 81 mountain passes (gaps, not mountains), 16 features on the Moon and Mars 6 undersea ridges and 3 features that are not mountains (two ravines and a road). Mountains and birthplaces are placed in modern countries and continents with Natural Earth; anything south of 60 degrees is Antarctica. Occupations are grouped by keyword. Wikidata often lists several, so each person goes in one group: titles of rule (monarch, president, governor) first, then specific professions (officer, surveyor, explorer or aviator, scientist, clergy), then politics without a title (politician, diplomat, lawyer), then arts and business, then generic labels (military personnel, engineer, university teacher, writer). Other rules give other shares; the order of the groups is robust, the exact percentages less so.
Checks. I read every mountain whose name does not contain its namesake's name (49 wrong links removed: the Galápagos islands linked to the English nobles of their old names, Lenin Peak linked to its former and its Tajik namesakes, Mount Clay to Ronald Reagan, former names such as Mount Stalin and Mount Pétain, and hills named after a saint through a church, chapel or shrine). I left 59 birthplaces off the map because Wikidata gives only a country, state, kingdom or empire (for example a birthplace of "England" placed at the middle of England), and corrected two (Lyon Playfair was born at Chunar in India, not in Haiti; Mount Olga, now Kata Tjuta, was named in 1872 after Queen Olga of Württemberg, not the later Grand Duchess Olga born in 1895). Elevations in Wikidata are sometimes in feet without saying so: 112 values are read as feet, those higher than their country's highest point and a few more found by hand. Wikidata is not a complete list of named mountains, and its coverage favours places with active editors (the Sierra Nevada, Svalbard, New Zealand). Modern borders are applied to old birthplaces, so a person born in the Russian Empire may count for Belarus or Ukraine.
