Konstanty Jodko-Narkiewicz

Konstanty Jodko-Narkiewicz, also known as Konstanty Narkiewicz-Jodko (1901–1963), was a Polish geophysicist who specialized in studying cosmic radiation. He was also a mountaineer, Arctic explorer, and balloonist.

Jodko-Narkiewicz trained in natural sciences and geography, gaining a doctorate in physics. Professionally he specialized in the study of cosmic radiation. In the 1930s, he was an assistant at the Physical Institute of Warsaw University.

He found a happy marriage between his career as a physicist and his interest in climbing. For instance, he combined a climbing expedition to the Andes in 1934 with a project to measure geomagnetic effects on cosmic rays.

Between 1933 and 1939, of the seventeen papers on cosmic-ray physics published in Poland, Jodko-Narkiewicz was author or co-author of twelve.

An experienced alpinist, Jodko-Narkiewicz also climbed mountains in Africa and Spitsbergen.

In 1929 he climbed the Iceland glacier Langjökull.

In 1933–1934 he led a Polish expedition organized by the Tatra Society to the Andes, beginning with the Cordillera de la Ramada, a mountain range in Argentina. The party included Stefan W. Daszynski, Jan K. Dorawski, Wiktor Ostrowski, Adam Karpiński, meteorologist and equipment designer, and Stefan Osiecki, cameraman, and it made the first ascents of Mercedario, Alma Negra, Pico Polaco, La Mesa, and Cerro Ramada, then proceeded south to climb the better-known Aconcagua, the highest mountain in the Americas. The Polish Glacier of Aconcagua was named after this expedition, which originated an alternative route to the peak along the glacier.
