Ivan ZavadskyBorn in 1780 near Hadyach in Poltava Oblast. He was a circumnavigator and polar explorer, cartographer, hydrographer, and collector of natural history collections.
During 1819–1821, he served as deputy captain on the warship Vostok (Russian: Шкхид), which made a circumnavigation of the Southern Ocean in search of a route to the South Pole. This expedition was one of the first to discover Antarctica and the islands near it: the South Sandwich Islands, Alexander I, and Peter I. Since the days of Soviet historiography, Ivan Zavadovsky has been called a Russian, as has Lysyansky.

One volcanic island was named in honor of Zavadovsky. In 2016, the government of South Georgia and the South Sandwich Islands printed four postage stamps "Zavadovsky Island". Another island in the Western Ice Shelf near Antarctica was also named after him. In Oleksandr Dovzhenko's film story "Antarctica", Ivan Zavadovsky is one of the main characters. Epifanij DrowniakNikifor Drovniak (real name Epifany Drovniak) was a Ukrainian primitivist artist of Lemko origin, born on May 21, 1895 in the city of Krynica (now Krynica-Zdrój, Poland) and died on October 10, 1968 in Folusz. His life was full of difficulties: he had speech and hearing impairments, lived in poverty and loneliness, and was often considered mentally ill. Despite this, Nikifor created over 40 thousand works, mostly watercolors, on paper, cardboard, notebook covers, and other improvised materials.  
His work includes self-portraits, landscapes of Krynica, and images of churches and city panoramas. In the 1930s, his works were discovered by Ukrainian artist Roman Turin, who presented them in Paris, which brought Nikifor some recognition among artists. However, real recognition came only in the 1960s thanks to the support of the Polish artist Marian Włosinski, who organized exhibitions of his works in Warsaw and other cities. 
After Nikifor's death, his legacy was preserved, and today
