Short History Of...

The Conquest of Everest

December 29, 2025

Key Takeaways Copied to clipboard!

  • The 1952 Swiss expedition, featuring Tenzing Norge and Raymond Lombert, set a new altitude record of 28,200 feet and marked the first time a Sherpa was recognized as a full team member, not just a porter. 
  • The 1924 British attempt by George Mallory and Andrew Irving ended in tragedy, leaving an enduring mystery as to whether they reached the summit before their disappearance, evidenced partly by the later discovery of Mallory's body. 
  • The successful 1953 British expedition, led by Colonel John Hunt and utilizing technological advancements from WWII, succeeded with the climbing pair Edmund Hillary and Tenzing Norge, though political complexities arose regarding the recognition of Tenzing. 
  • Mount Everest was originally named Peak 15 until 1856, when it was renamed after retired Surveyor General George Everest, despite objections from Everest himself who preferred indigenous names like Sagamatta or Kamalangma. 

Segments

1952 Swiss Expedition Failure

(00:00:26)
  • Key Takeaway: Tenzing Norge and Raymond Lombert turned back 800 feet from the summit in May 1952 due to faulty oxygen supply and altitude sickness.
  • Summary: Tenzing Norge and his companion, Raymond Lombert, were forced to retreat from Everest in 1952, despite setting a new altitude record of 28,200 feet. Tenzing suspected their oxygen supply was faulty, leading to concerns about ‘mountain madness.’ Lombert, who had previously lost toes to frostbite on Mont Blanc, was recognized as a full team member by the Swiss explorers.
Naming and Early Survey

  • Key Takeaway: Radhanath Sikdar, a 19-year-old Bengali mathematician, discovered in 1852 that Peak 15 was the world’s highest mountain, though it was later named after Sir George Everest.
  • Summary: The mountain, initially called Peak 15, is located in the Himalayas, straddling the border of Nepal and Tibet. Sikdar’s 1852 measurement of 29,000 feet was extraordinarily accurate, only about 30 feet off modern satellite measurements. Sir George Everest preferred indigenous names like Sagamatta (Nepal) or Kamalangma (Sherpa).
Early British Attempts

(00:07:01)
  • Key Takeaway: British climbers secured permission for attempts starting in 1922, but early efforts lacked modern meteorological data, exemplified by Mallory’s reliance on slow postcards.
  • Summary: The era of ’trophy exploration’ drove early attempts on Everest following its measurement in the 1850s. The 1924 attempt by Mallory and Andrew Irving was hampered by atrocious weather, as they had no reliable forecasting information. Mallory’s famous justification for climbing was simply, ‘Because it is there.’
Mallory’s Fate and Mystery

(00:11:13)
  • Key Takeaway: George Mallory’s body was found in 1999, but the missing photograph of his wife suggests he might have reached the summit before dying on the descent.
  • Summary: Andrew Irving’s ice pick was found in the 1930s, followed by the discovery of a body identified as G. Mallory in 1999. The absence of a photograph Mallory intended to leave on the summit fuels speculation that he and Irving were the first to conquer Everest. Experts consider it unlikely due to the climbing difficulties, especially with the inexperienced Irving.
Post-War Exploration and Yeti

(00:13:21)
  • Key Takeaway: Nepal opening up after WWII allowed access to the south side, where Eric Shipton photographed a massive footprint attributed to the Yeti in 1951.
  • Summary: The opening of Nepal enabled new routes from the south, leading Eric Shipton to explore the South Col in 1951. Shipton photographed a large footprint, fueling fascination with the Yeti, though some friends suspected the renowned practical joker was playing a prank. The Himalayas were seen as a realm of fantasy where such cryptozoological stories thrived.
1953 British Expedition Planning

(00:17:03)
  • Key Takeaway: Colonel John Hunt was appointed leader of the 1953 British assault due to his military background and systematic approach, emphasizing superior technology like prototype breathing apparatus.
  • Summary: Hunt was chosen over Shipton to lead the 1953 attempt, as the British were under intense pressure to succeed before the French and Swiss had slots. Hunt tested new equipment, including windproof nylon and improved oxygen systems, in a decompression chamber at Farnborough Airport. The expedition shipped 15 tons of supplies to Kathmandu before trekking to Base Camp.
Team Assembly and Trek

(00:22:50)
  • Key Takeaway: Hunt recruited Tenzing Norge, the Sherpa leader from the 1952 Swiss expedition, and befriended Edmund Hillary, a determined New Zealander beekeeper, during the trek to Base Camp.
  • Summary: Tenzing Norge, already recognized for his leadership, joined Hunt’s team despite initial ambivalence about working with the British post-colonially. The 175-mile trek from Kathmandu to Base Camp (18,000 feet) was an endurance test for the 350 local porters, who were paid three rupees per day. Hillary, a seasoned climber despite his humble description as a beekeeper, formed a friendship with Tenzing en route.
Ascending to Death Zone

(00:28:28)
  • Key Takeaway: The Kumbu Ice Fall, deemed ‘impossible’ by Mallory, was navigated by Shipton’s team using ladders and ropes, becoming the most dangerous barrier on the South route.
  • Summary: Base Camp was established on the Kumbu Glacier, below the ‘death zone’ (above 26,000 feet) where human cells die off. The expedition’s first major obstacle was the Kumbu Ice Fall, which required establishing a route known as ‘Mike’s Horror’ to reach Camp 2 at the Western Cwm. The South Col camp (Camp 8) was set at 26,000 feet, right on the edge of the death zone.
First Summit Attempt

(00:36:40)
  • Key Takeaway: The first summit pair, Charles Evans and Thomas Bodillon, reached the false South Summit on May 26, 1953, but turned back due to exhaustion and low oxygen, realizing Everest had two summits.
  • Summary: After Wilf Noyce tested the oxygen apparatus successfully, the Great Lift moved supplies to the South Col. Evans and Bodillon were the first pair to use the improved oxygen systems for a summit push. They reached the South Summit, realizing it was a false peak about 200 feet below the true summit, and retreated after an 11-hour effort.
Successful Summit Ascent

(00:39:35)
  • Key Takeaway: Edmund Hillary and Tenzing Norge reached the summit on May 29, 1953, overcoming the final obstacle, a 40-foot rock face later named the Hillary Step, using chimneying technique.
  • Summary: Hillary and Tenzing set out three days after the first attempt, reaching the South Summit by 9 a.m. They crossed a dangerous ice cornice before Hillary scaled the final vertical rock face, the Hillary Step, by jamming himself in the crack. They spent only 15 minutes on top, where Tenzing left Buddhist offerings and Hillary buried a cross.
Aftermath and Legacy

  • Key Takeaway: The news of the conquest coincided with Queen Elizabeth II’s coronation, but political disputes arose over Tenzing Norge not receiving a knighthood, which Hillary and Hunt did.
  • Summary: The world learned of the conquest on June 2, 1953, linking it to the Queen’s coronation, though Tenzing was omitted from some newspaper photos. A dispute arose over who stepped first, though both climbers agreed they succeeded as a team. Hillary later revealed in his autobiography that Tenzing was the first to set foot on the summit, breaking their long-held pact of silence.
