Who was the youngest non Sherpa to climb Everest and how old was s he?

It was Mark Pfetzer who went up with a guy named Ray Dorr and his leader Henry Todd on a trek to the top of Everest in '96. He survived the tragedy (storm) at the top. Scott Fischer and Rob Hall did die though. He was 16 when he climbed Everest and he's American. He has climbed other mountains including, Cotopaxi in Ecuador, Rainier in Washington, Huascaran in Peru, Aconcagua (the largest mountain in the Americas) in Argentina, Ama Dablam in Nepal, Kilimanjaro in Tanzania (he was assistant guide), and cho oyu in Nepal. His dad survived cancer when pfetzer climbed Everest in '96. Pfetzer is now a police officer, though.
