Captain George Francis Kosco (1 April 1908 – 11 June 1985) was a United States Navy aerologist and polar explorer. Kosco was born in Ramsaytown, Pennsylvania, on 1 April 1908. He was a Slovak American: his father had come from Oľšov, and his mother from Plavnica. His family name had been "Kvasnak", but this was changed to "Kosco" when his parents emigrated to the United States. Kosco graduated from the United States Naval Academy in 1930, and earned a master's degree in weather aerology from the Massachusetts Institute of Technology in 1940. His dissertation, co-authored with John O. F. Dorsett, was called Winter weather types of the eastern North Pacific and adjacent coastal and island areas.
