On the reverse the founding Professor Kaminski portrait facing to the right, underneath his autograph, his name above is visible. The professor, who was born in 1921 became famous in 1957 when he was the first man outside the Soviet Union who detected the Sputnik 1 radio signals by a radio antenna set up in the meadow in front of his house. In 1961 he took over the leadership of the observatory he founded. He dealt with space exploration and not astronomy. The institute that he created became involved in the international research, and in 2009 first in Europe managed to catch the radar echoes from Venus. Kaminski did not live to see this, in 2002 at the age of 80 he died.
