Ueli Steck

Ueli Steck (4 October 1976 – 30 April 2017) was a Swiss rock climber and alpinist.

He was the first to climb Annapurna solo via its South Face (though this is disputed by some ), and set speed records on the North Face trilogy in the Alps.

This route had been climbed only a few times, the last of which was in 1991.

His plan was to climb the Hornbein Couloir to the summit, then proceed with a traverse to the peak of Lhotse, the world's 4th highest mountain.

This combination had not been achieved.

On 16 April, during preparations for the attempt, his climbing partner, Tenji Sherpa, suffered frostbite, which would take some weeks to heal.

Steck carried on with scouting and acclimatisation, climbing up to Everest's Camp 2, en route to the South Col. On April 29, he changed his plans, texting Tenji that he would climb the nearby peak of Nuptse instead, and did not respond to a follow-up question.

On 30 April, he began climbing at around 4:30 AM with a French climber named who was attempting to climb Everest.

Lowe and Bridges were killed in an avalanche in 1999 while searching for a route up Shishapangma to attempt the first ski descent.

Steck was born as the third son to a copper smith in the town of Langnau in the Emmental valley in Switzerland.

As a child he played hockey and joined his father on ski tours.

He was a carpenter by training and in adulthood lived in Ringgenberg near Interlaken, Switzerland.

In June 2004, he and Stephan Siegrist climbed the Eiger, Mönch and Jungfrau within 25 hours.

Another success was the so-called "Khumbu-Express Expedition" in 2005, for which the climbing magazine Climb named him one of the three best alpinists in Europe.

The project consisted of the first solo climb of the north wall of Cholatse (6,440 m) and the east wall of Taboche (6505 m).

Steck set his first speed record on the North Face of the Eiger in 2007, climbing it in 3 hours and 54 minutes.

The record was lowered by Steck himself to 2 hours 47 minutes 33 seconds the following year.

In May 2008, climbing Annapurna, he broke off his ascent due to an avalanche threat, but the next week climbed to assist Spanish climber Iñaki Ochoa de Olza, who had collapsed.

Medical help was slow in coming and the Spanish climber died despite Steck's help.

In 2008, Steck was the first recipient of the Eiger Award for his mountaineering achievements.

He won two Piolet d'Or awards, in 2009 and 2014.

Popier also questioned Steck's 2011 ascent of Shishapangma.

On 27 April 2013, while climbing with Simone Moro to prepare for a traverse next spring of Everest and Lhotse, Steck got into an altercation with disgruntled sherpas that according to The Guardian: "... went viral and Steck, wholly blameless in the affair, became severely depressed and disheartened".

On 8 and 9 October 2013 Steck soloed the Lafaille route on the South Face of Annapurna.

on the main and highest part of the face; this was his third attempt on the route and has been called "one of the most impressive Himalayan climbs in history", with Steck taking 28 hours to make the trip from Base Camp to summit and back again.

The veracity of his claim was questioned by some due to absence of any photographs or GPS tracking data.

According to mountaineering journalist Rodolphe Popier, who carried out an analysis of Steck's claim and found it questionable, others skeptical of Steck have included former editor-in-chief of German mountaineering magazine Bergsteiger Andreas Kubin, Rolando Garibotti, Alexander and Thomas Huber, fr:Yannick Graziani, Catherine Destivelle, George Lowe, and Leslie Fuczko, former president of the fr:Groupe de Haute Montagne.

fr:François Marsigny, director of the mountaineering department of fr:École nationale des sports de montagne, France's national mountain guide school in Chamonix, said a "cluster of unfavourable clues" surrounded Steck's climbs.

Steck's claim, however, was supported by two sherpas from his team.

Steck's feat was the first solo ascent of Annapurna, which won him his second Piolet d'Or.

Christian Trommsdorff, chairman of the Piolet d’Or organizing committee, received serveral emails from "Swiss-German and German alpinists and journalists" questioning Steck's claim and his nomination for the prize.

In the winter of 2014/15, Steck and Michael Wohlleben linked up the three north faces of the Tre Cime di Lavaredo/Drei Zinnen in 16 hours.

In the summer of 2015, he climbed all 82 summits in the Alps higher than 4000 meters in 62 days without the use of motorized travel.

Two days slower than the 60-day record, his time included a period when Steck had suspended the tour on 22 July, after his climbing partner on the Aiguille de Rochefort, Martijn Seuren, had fallen to his death on this final peak to make him the first Dutch person to climb all 82 4000ers.

Later that year Steck set a new record for the North Face of the Eiger, soloing it in 2 hours 22 minutes and 50 seconds.

In April 2016, Steck and his German mountaineering partner, David Göttler, found the bodies of Alex Lowe and paraglider David Bridges.

Having previously summitted Mount Everest, Steck died on 30 April 2017, after a fall during an acclimatizing climb for an attempt on the Hornbein route on the West Ridge of Everest without supplemental oxygen.

At the age of 17, Steck achieved the 9th difficulty rating (UIAA) in climbing.

As an 18-year-old he climbed the North Face of the Eiger and the Bonatti Pillar in the Mont Blanc massif.
