The Carl von Ossietzky University of Oldenburg (German: "Carl von Ossietzky Universität Oldenburg" ) is a university located in Oldenburg, Germany.
 It is one of the most important and highly regarded educational facilities in northwestern Germany and specialises in interdisciplinary & sustainable development studies and renewable energy studies with focus on solar and wind energy.
Johannes Browallius (1707–1755), also called John Browall, was a Finnish and Swedish Lutheran theologian, physicist, botanist and at one time friend of Swedish taxonomist Carl Linnaeus.
Die Weltbühne (English: "The World Stage") was a German weekly magazine focused on politics, art, and business.
 The "Weltbühne" was founded in Berlin on 7 September 1905 by Siegfried Jacobsohn and was originally created strictly as a theater magazine under the title "Die Schaubühne".
 It was renamed "Die Weltbühne" on 4 April 1918.
 After Jacobsohn's death in December 1926, Kurt Tucholsky took over the leadership of the magazine, which he turned over to Carl von Ossietzky in May 1927.
 The Nazis banned the publication after the Reichstag fire, and its last issue appeared on 7 March 1933.
 In exile the magazine was published under the title "Die neue Weltbühne" ("The New World Stage").
 After the end of World War II, it appeared again under its original name in East Berlin, where it endured until 1993.
 In 1997 the magazines "Ossietzky" and "Das Blättchen" appeared, following the model of "Die Weltbühne".
Hans Carl von Carlowitz, originally "Hannß Carl von Carlowitz" (24 December 1645 - 3 March 1714), was a German tax accountant and mining administrator.
 His book "Sylvicultura oeconomica, oder haußwirthliche Nachricht und Naturmäßige Anweisung zur wilden Baum-Zucht" (1713) was the first comprehensive treatise about forestry.
 He is considered to be the father of sustainable yield forestry.
Critica Botanica ("Critique of botany", Leiden, July, 1737) was written by Swedish botanist, physician, zoologist and naturalist Carl Linnaeus (1707–1778).
 The book was published in Germany when Linnaeus was twenty-nine with a discursus by the botanist Johannes Browallius (1707–1755), bishop of Åbo.
 The first and only edition was published in July 1737 under the full title "Critica botanica in qua nomina plantarum generica, specifica & variantia examini subjiciuntur, selectoria confirmantur, indigna rejiciuntur; simulque doctrina circa denominationem plantarum traditur.
 Seu Fundamentorum botanicorum pars IV Accedit Johannis Browallii De necessitate historiae naturalis discursus".
