Reference excerpt

Georg Heinrich Freiherr von Langsdorff (8 April 1774 – 9 June 1852) was a German naturalist and explorer, as well as a Russian diplomat, better known by his Russian name, Grigori Ivanovich Langsdorf. He was a naturalist and physician on the First Russian circumnavigation from 1803 to 1806. Later Langsdorff was nominated consul general of Russia in Rio de Janeiro, Brazil. From there he organized expeditions to Minas Gerais (1813 to 1820) and the Langsdorff Expedition to the Amazon rainforest, which lasted from 1825 to 1829.

Life Georg Heinrich Langsdorff was born in April 1774 at Wöllstein, in the Electoral Palatinate, Holy Roman Empire. He studied medicine and natural history at the University of Göttingen, Germany, under Johann Friedrich Blumenbach and graduated with a doctorate in medicine and surgery in 1797. That same year he accompanied Christian August, Prince of Waldeck and Pyrmont, Field Marshal of the Portuguese land army, to Lisbon. However, after Prince Christian died in 1798, he set up a private medical practice, and subsequently accepted the post of surgeon to English troops in Portugal. After the Treaty of Amiens he visited London and Paris, and returned to Göttingen. He was appointed a member and correspondent of the Russian Imperial Academy of Sciences on 29 January 1803. He requested to join the scientific crew of the First Russian voyage of circumnavigation but received a polite rejection letter; the expedition's ships would take on board the official naturalist at Copenhagen. The day he received the letter he left Göttingen and reached Copenhagen in seven days, where the Russian ships were still docked. He implored with ambassador to Japan Nikolai Rezanov, and supported by Captain Adam Johann von Krusenstern, his petition to join the expedition was granted.

Russian Voyage of Circumnavigation

Langsdorff participated as a naturalist and physician in Krusenstern's Russian expedition from 1803 to 1805. On this journey he visited Falmouth in England, Tenerife in the Canary Islands, Santa Catarina Island in Brazil, Nuku Hiva, the Hawaiian Islands, Kamchatka and Japan. When the expedition returned to Kamchatka he left with ambassador Nikolai Rezanov and headed to the northwest coast of North America. He explored the Aleutians, Kodiak and Sitka. At Sitka he met and befriended the American maritime fur trader John DeWolf, who sold the RAC his ship Juno. Langsdorff and Rezanov traveled sailed Juno to San Francisco to acquire food for Sitka. From Sitka, Langsdorff and DeWolf sailed to Petropavlovsk, then Okhotsk. From there both traveled overland across Siberia separately making their way to Saint Petersburg, where Langsdorff arrived in 1808. He encountered various problems on his journey. For example, in Brazil the humidity caused the botanical samples to rot, and ants came and ate his insect collections. On his way back to Saint Petersburg he lost part of his herbarium collection in the Lena between Yakutsk and Irkutsk. However he was able to publish his findings in books such as Plantes recueilles pendant le voyage des Russes autour du monde: expédition dirigée par M. de Krusenstern. (Plants collected during the Russians' voyage around the world: expedition led by Mr. Krusenstern), published in 1810.

Brazil In 1813 Langsdorff was nominated consul general of Russia in Rio de Janeiro, Brazil. He acquired a farm (named "Mandioca", or manioc) in the north of Rio and collected plants, animals and minerals. He hosted and entertained foreign naturalists and scientists, such as Johann Baptist von Spix (1781–1826) and Carl Friedrich Philipp von Martius (1794–1868), and explored the flora, fauna and geography of the province of Minas Gerais with French naturalist Augustin Saint-Hilaire from 1813 to 1820.

The Langsdorff Expedition

In 1821 he proposed to the Tsar Alexander I and to the Academy of Sciences to lead an ambitious exploratory and scientific expedition from São Paulo to Pará, in the Amazon, via a fluvial route. In March 1822, he returned to Rio in the company of scientists Édouard Ménétries (1802–1861), Ludwig Riedel (1761–1861), Christian Hasse and Nester Rubtsov (1799–1874), who would take care of zoological, botanical, astronomical and cartographical observations during the expedition. With the aim of illustrating and documenting his findings, the Baron hired painters Hércules Florence, Johann Moritz Rugendas and Adrien Taunay. The inventor of the bicycle Karl von Drais was also a participant in the expedition.

Worked examples

Example 1 — a first encounter with Georg von Langsdorff

Start with the simplest possible case. Write down what Georg von Langsdorff claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Georg von Langsdorff before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Georg von Langsdorff ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Georg von Langsdorff

In research: Georg von Langsdorff appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Georg von Langsdorff in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Georg von Langsdorff is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1774 births, 1852 deaths, 19th-century German botanists, so understanding it makes those chapters shorter.
In everyday life: Look for Georg von Langsdorff outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
