Karl Wien was born in Munich in 1906 and studied geography at the University of Berlin. He specialized in glaciology and led scientific expeditions to the Alps and polar regions, combining fieldwork with academic research. Wien published several papers on mountain geomorphology and the effects of climate on glaciers. A passionate mountaineer, he made first ascents on remote peaks, contributing valuable data to his discipline. His work bridged practical exploration and theoretical geography, earning recognition among scholars. Tragically, he died in a mountaineering accident in 1937, leaving an enduring legacy in both geography and exploration.

Born in 1933 near Moscow, Yevgeny Khrunov joined the Soviet Air Force and graduated from the prestigious Air Force Academy. Selected as a cosmonaut in 1964, he served as flight engineer on Soyuz 5 in January 1969. During this mission, he performed an extravehicular transfer to the docked Soyuz 4 spacecraft, contributing to one of the early Soviet EVA achievements. Decorated as a Hero of the Soviet Union, Khrunov later worked on cosmonaut training and mission planning. He retired from active service in 1988 and held a leadership role at the Yuri Gagarin Cosmonaut Training Center. Khrunov passed away in 2000, remembered as a pioneer of human spaceflight.
