About the Author:

IN THE mid year of 1955, I orchestrated to go along with a few companions who were going into the Alps. Alfred Tissieres, then a Fellow at King’s, had said he would get me to the highest point of the Rothorn, and even despite the fact that I freeze at voids this didn’t appear to be an ideal opportunity to be a defeatist. So subsequent to getting fit as a fiddle by giving an aide a chance to lead me up the Allinin, I took the two-hour postal transport excursion to Zinal, trusting that the driver was not carsick as he reeled the transport around the restricted street bending over the falling rock inclines. At that point I saw Alfred remaining before the lodging, conversing with a since quite a while ago mustached Trinity wear who had been in India amid the war. Since Alfred was still out of preparing, we chose to spend the evening strolling up to a little eatery which lay at the base of the tremendous icy mass falling down off the Obergabelhorn and over which we were to walk the following day. We were just a couple minutes outside of anyone’s ability to see of the inn when we saw a gathering descending upon us, and I rapidly remembered one of the climbers. He was Willy Seeds, a researcher who quite a while before had worked at King’s College, London, with Maurice Wilkins on the optical properties of DNA strands. Willy soon spotted me, backed off, and immediately gave the feeling that he may expel his rucksack and talk for some time. Be that as it may, all he said was, “The manner by which’s Honest Jim?” and rapidly expanding his pace was soon underneath me on the way.
