Was a German linguist. He developed the Wellentheorie ('wave theory') of language development.Schmidt was born in Prenzlau, Province of Brandenburg. He studied philology (historical linguistics) with the great Indo-Europeanist August Schleicher and specialized in Indo-European, especially Slavic, languages. He earned a doctorate in 1865 and worked from 1866 as a teacher at a gymnasium in Berlin.In 1868 Schmidt was invited by the University of Bonn to take a position as professor of German and Slavic languages. In Bonn he published the work Die Verwandtschaftsverhältnisse der indogermanischen Sprachen ('The Relationships of the Indo-Germanic Languages', 1872), which presented his Wellentheorie ('wave theory'). According to this theory, new features of a language spread from a central point in continuously weakening concentric circles, similar to the waves created when a stone is thrown into a body of water.

An American geographer and explorer. His work has been mapping and describing caves and geysers.In 1996, Glennon and Jon Jasper discovered an entrance to the Martin Ridge Cave System, Kentucky, and explored connections to nearby Jackpot and Whigpistle Caves (Groves, C.G. 1998). The combined cave system is 51 kilometers (32 miles) long (Gulden, B. 2005). The cave is hydrologically connected to Mammoth Cave---the world's longest cave (Quinlan J.F. and Ray, J. 1989). Glennon also was involved in the discovery of one of the largest cave chambers in Kentucky (Yonker, R. 2003).

Was an early American botanist and horticulturalist. Carolus Linnaeus said he was the "greatest natural botanist in the world."[2] He considered himself a plain farmer, with no formal education beyond the local school, although he had a lifelong interest in medicine and medicinal plants, and read widely.
