I took the measure of Sir Edmund Hillary’s greatness last summer, while on a three-week trek in the Everest region of Nepal. In our second week on the trail, my fellow climbers and I perched atop a low adjoining peak and gazed up in wonder at Everest’s 29,035-foot summit. It was there, on May 29, 1953, that Sir Edmund stood alongside Tenzing Norgay to become the first men to climb the world’s highest mountain.

In Nepal, trekkers are advised never to drink water from public sources, unless it is boiled first, and it’s a good idea to add an iodine tablet as well. Even then it’s possible to get sick from treated water, as I found to my discomfort a week or so later. In the high mountain villages, human waste and yak dung regularly pollute the water supply. But not in the small Sherpa village of Khumjung, because Sir Edmund gave the villagers there a safe water system. There is also a Sir Edmund school in Khumjung, and a Sir Edmund medical clinic in the neighboring village of Khunde.

The origins of the Khumjung School, the first of Sir Edmund’s philanthropic efforts in Nepal,

date back to 1960. Sir Edmund, masking his first return visit since the 1953 expedition, embarked on a somewhat quixotic search for evidence of the legendary Yeti (abominable snowman).

The school went up in 1961. And over the next four decades, the charitable organisation Sir Edmund subsequently founded, the Himalayan Trust, raised funds for more than two dozen additional schools in the Solu-Khumbu region, plus clinics, hospitals, bridges, airfields, and projects promoting clean water and reforestation. Every village we visited last summer had pictures and posters of Sir Edmund (locals called him “Sir Ed”). But there is one photographic image of Sir Edmund you will never see, in Nepal or anywhere else, one of him standing atop Mount Everest. And that is because it doesn’t exist.

Sir Edmund brought a camera with him that day in 1953 to the summit and took a photo of his Sherpa companion, Tenzing Norgay, holding his ice ax aloft in a triumphant gesture. That photo was featured on the cover of Life magazine and became one of the iconic images of the 20th century.

Ed Douglas, one of Tenzing’s biographers would later note, “Some climbers might have taken the chance on Tenzing getting lucky.” I think the truth is that Sir Edmund, who fully expected to go back to the family business of beekeeping when he got back from Everest, didn’t care whether his moment of glory was recorded. He was a strong, ambitious climber, and he had the drive to make it to the top. But he was also a simple, uncomplicated, and deeply modest man. And in the years that followed his day on the top of the world, he went on to do a lot of good.

So when I learned of his death last week, I wanted to raise a toast in his memory. My only regret is that, I couldn’t do it with some of that icy cold and remarkably clean Khumjung water. Here’s to you, Sir Ed. — The Christian Science Monitor
