My second memory-glimpse is also of Everest, but now of the circumstances are very different.
This time it is May 29, 1953, in the very last days of our expedition, and I am at Camp IV, at about 21,000ft, with John Hunt, our leader and a few of the British climbers and Sherpa. The day is brilliant, all seems blue, white and crystal-clear, and we are awaiting the turn of Tenzing Norgay, the most celebrated of all the Sherpa, and Ed Hillary, another New Zealander, from their attempt to reach the summit - the climax of our adventure.
George Lowe has climbed up there, far above his old work-place on the Lhotse face, to meet them and see them safely down, and I am here in the mountain sunshine of the Western Cwm to learn whether they have made it to the top. If they have, I have it in my power to make the pair of them two of the most famous men on Earth.
And here they come! We rush up the snow slope to meet them, grizzled Hunt in the lead, a cluster of us slipping and sliding around him, with me in the middle already planning my night's dispatch. Here they come! Ed and Tenzing, still roped together, look exhausted, almost dazed, but leading them down to meet us is George Lowe, and he looks radiant. He has always walked proud, with an almost military bearing, and now, with his ice-axe in his left hand, like a cocky colour-sergeant, he is giving us an exuberant thumbs-up with his right. They've done it!
Everest is climbed, mankind has reached the summit of its planet, and George Lowe is its stylish, pleased and proper herald.
And here's my third retrospection. This time we are on the other side of the world, in Maryland, or Virginia, or perhaps California - I forget exactly where. I am with George Lowe, Ed Hillary and Charles Evans, our deputy leader on Everest, on a lecture tour in the United States to commemorate that first climbing of the mountain.
We (or rather they, because I am only there as a kind of spokesperson) have been treated like heroes, with banquets and honorary citizenships and presidential receptions and in my memory now I see the four of us lined up to shake hands with a wonderfully generous public, somewhere or other in the Great Republic. There is Ed, the hero of heroes, shortly to be immortalised on postage-stamps and dressed in antique fineries as a Knight of the Garter. There is Charles Evans, the brain surgeon, soon to be knighted too as Principal of Bangor University. There is me, looking sheepish but undeniably pleased with myself.
And there is George, leaning forwards slightly to offer his hand to a glowing matron. He is laughing, perhaps at a joke of hers, perhaps at a sally of his own, and she is laughing too. What does this image suggest to me? Why, it reminds me that George Lowe the mountaineer is a man of sweet charm and courtesy. In an age when the very word is going out of fashion, he is a gentleman.
So what? What have my memories contributed? Nothing perhaps. We are back where we started, with the well-known fact that Wallace George Lowe is a brave, friendly, tough and honest mountain-climber, from New Zealand."
