Leo Bagrow

Leo Bagrow is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Leo Bagrow rather than just read about it. In short: Leo Bagrow (born Lev Semenovich (Solomonovich) Bagrov; 6 July 1881 – 10 August 1957) was a Russian-born historian of cartography, founder of the journal Imago Mundi. He grew up in Russia, and initially pursued a career within the Imperial Russian Navy.

Key takeaways

  • Leo Bagrow belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Leo Bagrow to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Leo Bagrow from memory before moving on to harder problems.

Reference excerpt

Leo Bagrow (born Lev Semenovich (Solomonovich) Bagrov; 6 July 1881 – 10 August 1957) was a Russian-born historian of cartography, founder of the journal Imago Mundi. He grew up in Russia, and initially pursued a career within the Imperial Russian Navy. In naval service, he traveled extensively to conduct surveying work. During this time, he encountered the historical map collection of Arctic explorer Adolf Erik Nordenskiöld in Helsinki and became interested in the history of mapmaking. Following the outbreak of World War I, he taught navigation and what may have been the world's first academic course on the history of geodesy and cartography in Saint Petersburg. By this time he had also begun publishing scholarly articles and receiving international recognition within his field. Following the Russian Revolution, he fled the country, never to return. He settled in Berlin, where he began working as a dealer in antique maps. There he met Hans Wertheim, with whom he founded the world's first international scholarly journal dedicated to the history of cartography, Imago Mundi. The first issue was published in 1935; Wertheim, who was Jewish, was soon forced to flee Nazi Germany to Belgium, where he died. Bagrow managed to find a new publisher for the journal in London, but stayed in Germany until April 1945, when he was evacuated with the help of Swedish colleagues with the last diplomatic flight from Berlin to Stockholm. He would spend the rest of his life in Sweden, where he was granted citizenship in 1952 and where he enjoyed the patronage of King Gustav VI Adolf.

Early life in Russia

Leo Bagrow was born in the settlement of Vereteye, close to Solikamsk in the Russian Empire. His father was a Jewish engineer, working on the railway. His mother died when he was still an infant. After having attended school in Tambov for the first years of his life, he was enrolled in the prestigious private Gurevich gymnasium in Saint Petersburg in 1899. Among the schoolmates with whom he became friends was the future composer Igor Stravinsky; Bagrow himself had a keen interest in music throughout his life. He graduated from school in 1902 and then enrolled as a cadet in the Imperial Russian Navy. In the same year he began academic studies at Saint Petersburg State University in geography, and later Bagrow also pursued studies at the Imperial Archaeological Institute. His university studies were cut short by the outbreak of the Russo-Japanese War in 1904 and by the subsequent Russian Revolution of 1905. He left the university for the Navy in 1905, and worked in the Naval Ministry's Hydrographical Office 1906–1908 and again 1912–1914. In 1909 he married Olga Ladan.

During his years at the Hydrographical Office he travelled extensively. He went on surveying trips to the Caspian Sea, the Gulf of Finland, the Kara Sea, the lower Amur and Kamchatka. He also went abroad: twice to Japan, and also to Korea, China, present-day Thailand and Myanmar. While working in the Gulf of Finland, he had the opportunity to study the collection of historical maps of explorer Adolf Erik Nordenskiöld, kept in the library of Helsinki University (today the National Library of Finland). The encounter with Nordenskiöld's collection spurred his own interest in the history of cartography, and he regarded the explorer as his "master", dedicating publications to him in 1917 and 1950. During his travels he also took up the habit of seeking out and purchasing historical maps of the regions he visited, and it appears that it was during these years his life-long passion for the history of cartography was born. He published his first scholarly publication in 1912. Following the outbreak of World War I, Bagrow was promoted to the rank of Captain and returned to Saint Petersburg in 1916 where he taught navigation at the Technical School. He was also appointed professor in geography and history and supposedly taught a course on the history of geodesy and cartography at the Geographical Institute with his colleague, Dimitry Rudnev. Though unconfirmed, this would make it the first known academic course on the history of cartography worldwide. Towards the end of the war, Bagrow had already published extensively in Russian on the history of mapmaking, and received his first international recognition following a work on the Theatrum Orbis Terrarum by Abraham Ortelius.

Exile in Germany Bagrow, who came from a wealthy family within the establishment of the Russian tsarist regime, was an avowed anti-Bolshevik. Following the Russian Revolution, he and Olga fled Russia in November 1918. They left behind most of their possessions, including Leo Bagrow's sizeable library and map collection. The couple settled in Berlin, in the area of Charlottenburg. Leo Bagrow never returned to Russia. In Berlin, he sustained himself by dealing in antiques, including maps and books. He used his Russian origins to his benefits, acting as a broker for the sale of art and objects confiscated from the Russian Orthodox Church and Russian nobility by Soviet authorities, which were controversially sold abroad to raise cash for the new Soviet regime. He was at one time associated with the industrialist Hugo Stinnes, and purchased historical maps and atlases on his behalf. He also published in a Russian émigré magazine and in 1927 founded a "Circle of Lovers of Russian Antiquities", which came to include, among others, the poet Raisa Blokh and art historian Alexej A. Hackel. During his years in Berlin he also had the opportunity to travel internationally to search for cartographical material. He also began rebuilding a personal collection of maps and related items, and pursuing his particular interest in the history of cartography in Russia and adjacent lands. He also wrote a general history of mapmaking, and initiated a series of monographs on early maps.

Worked examples

Example 1 — a first encounter with Leo Bagrow

Start with the simplest possible case. Write down what Leo Bagrow 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 Leo Bagrow 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 Leo Bagrow 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 Leo Bagrow

In research
Leo Bagrow 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 Leo Bagrow 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
Leo Bagrow is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1881 births, 1957 deaths, 20th-century geographers, so understanding it makes those chapters shorter.
In everyday life
Look for Leo Bagrow 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.
