Charles S. Houston: Dr. Houston, well known to American Alpine Journal readers for his part in expeditions to Mts. Foraker, Nanda Devi and K2, was until recently Lieutenant-Commander Houston, U.S.N.R. During the war a flight surgeon in charge of various aspects of physiological research at the U. S. Navy Research Laboratory at Pensacola, Florida, he directed the Navy’s "Operation Everest” and other pioneer experiments in tracing the effects of altitude on the blood.
Albert H. Jackman: Lt. Col. Jackman, long an advocate of mountain troop training, served with the 10th Mountain Division in Italy.

Casualties from frostbite during air operations made his work of utmost importance.
Weldon F. Heald: During the war the issue of clothing to U. S. troops was changed from a hit-or-miss system to a scientific arrangement of climate zones based on maps prepared by Major Heald. The advantages of climatological topography to civilian mountaineers and travelers as well as to the military will be seen by reading his article.
H. Adams Carter: As Adams Carter shows in his article, he began intelligence work on mountain troop problems early in 1941 and continued on the broader phases of this problem throughout the war.
