August Thienemann

German limnologist and freshwater biologist. In the 1910s, through research on small crater lakes in the middle Rhine region, he discovered the relationship between lake depth, dissolved oxygen, and the species of benthic chironomids. This became the basis for subsequent lake typology. He became director of the Prion Limnological Institute and also served as a professor at Kiel University. He was one of the founders of the International Society for Theoretical and Applied Limnology, which was established in 1922, and later served as its president. In addition to researching lakes in central Europe, he conducted limnological surveys in the Sunda Islands (1928-1929), laying the foundations for research into tropical lakes. He published approximately 460 papers and books, occupying an important position in modern limnology.

ドイツの陸水学者、淡水生物学者。1910年代にライン川中流地方の小火口湖の研究から、湖の深さと溶存酸素、底生ユスリカの種類との関係をみいだした。これは、その後の湖沼類型の基本となった。プリョン陸水生物研究所所長となり、キール大学教授をも務めた。1922年に発足した国際理論応用陸水学会の発起人の一人で、のちに会長も務めた。中部ヨーロッパの湖沼研究のほか、スンダ列島の陸水調査（1928～1929）を行い、熱帯の湖沼研究の基礎をもつくった。論文・著書は約460編に及び、近代陸水学のなかで重要な位置を占めている。
