Vitor Negrete

Vítor Negrete (13 November 1967 – 19 May 2006) was a climber and the first Brazilian to reach the summit of Mount Everest without supplemental oxygen.

Among many other adventures, he had crossed the Amazon Rainforest and traveled from São Paulo state to the southernmost part of Argentina– Tierra del Fuego, Patagonia– on a bicycle.

[3] In May 2006, Negrete and his Brazilian teammate, Rodrigo Raineri, attempted to climb Mount Everest following the north ridge route without the aid of oxygen.

On May 16, they learned that, while making a summit bid, David Sharp, a fellow Asian Trekking member, had died on the mountain.

[4] On May 17, resting at Base Camp after a failed summit bid, Negrete told Raineri: “I am going tonight, without O2, without a Sherpa and without a sat-phone, since the batteries of the one I have are almost gone.
