Daniel Vergara Lope and Carlos Monge Medrano: two pioneers of high altitude medicine.

Daniel Vergara Lope from Mexico and Carlos Monge Medrano from Peru were brilliant scientists in their own countries. Both scientists studied high altitude physiology and defined the physiological and anatomical mechanisms of adaptation to high elevations. The Mexican physiologist proposed his ideas 40 years before his Peruvian counterpart. This paper studies the contribution of Vergara Lope and Monge Medrano to the understanding of high altitude medicine and proposes explanations of why history has given priority to Monge, whereas Vergara Lope is relegated to anonymity.
