Konstanty Jodko-Narkiewicz

For instance, he combined a climbing expedition to the Andes in 1934 with a project to measure geomagnetic effects on cosmic rays.

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.

[7] In 1936, with Stanislaw Siedlecki and Stefan Bernadzikiewicz, he took part in a Polish expedition which crossed West Spitsbergen from south to north.

[10] On 14 October 1938, in the Tatra Mountains, Jodko-Narkiewicz and Captain Zbigniew Burzyński attempted a stratospheric flight in the hydrogen balloon Star of Poland.

They were equipped with a Geiger-Mueller tube telescope, intending to measure the variation in intensity of cosmic rays at different altitudes.
