Johan Mey

Johan Mey 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 Johan Mey rather than just read about it. In short: Johan Mey (also Johann Mey, Juhan Mei; November 19, 1867 – April 5, 1927) was an Estonian navigator, hydrographer, surveyor, and military officer (a lieutenant colonel). Early life and education Johan Mey came from a family of seafarers from Hiiumaa, where he was born in the village of Sääre to Madis Mei (or Mey; 1837–1920) and Marie Mei (née Kimber, 1840–1924).

Key takeaways

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

Reference excerpt

Johan Mey (also Johann Mey, Juhan Mei; November 19, 1867 – April 5, 1927) was an Estonian navigator, hydrographer, surveyor, and military officer (a lieutenant colonel).

Early life and education Johan Mey came from a family of seafarers from Hiiumaa, where he was born in the village of Sääre to Madis Mei (or Mey; 1837–1920) and Marie Mei (née Kimber, 1840–1924). He developed an early interest in shipping and maritime affairs, and he joined a merchant ship at age 16. He studied for a few years at the Tallinn District School, and later at the Paldiski Martifime School and Liepāja Maritime School, becoming a long-distance helmsman. In his youth, Mey collected oral folklore by transcribing folk songs. Much of his material can be found in Jakob Hurt's collection.

Career In 1892, Mey was appointed a captain for ship construction at the Riga Military Port, and then he became interested in port construction and dredging. In 1897, he passed the officer's examination at the St. Petersburg Naval Cadet Corps. He was then enrolled in the reserve army as an ensign. At the outbreak of the Russo-Japanese War, Mey was called up for active service, appointed watch officer on the steamer Chaika, and also made head of dredging work at the Liepāja Military Port. In 1906, Mey supervised the hydrographic and dredging work in the Soela Strait. From 1908 to the fall of 1917, he supervised the same work at the new Tallinn Military Port (Miinisadam). During the same period, he also worked in the Finnish Straits; the work resulted in new fairways in Barösund and Barösund-Ekenäs, and several dredged shipping lanes near Porkkala. In 1914, Mey was sent to Germany, the Netherlands, and England to study modern port construction. In 1916, Mey took part in dredging the large strategic Kumari Channel in the Sea of Straits. He was one of the top specialists in Russia. He was awarded the Order of Saint Stanislaus second and third class, the Order of Saint Anna third class, and a large gold medal. In 1917, Mey was evacuated to St. Petersburg. From there, he chose to return to Estonia in 1920. In Estonia, Mey worked as a senior commanding officer in the Naval Forces Command Staff, and a few months later as commander of the minesweeper division. He remained there until the division was liquidated. On March 15, 1921, Johan Mey was assigned to the Fourth Department of the General Staff (the topo-hydrography department) as a cartographer. From 1921 to 1926, Mey mainly carried out measurements of Estonian ports, and he also compiled and edited publications for the topo-hydrography department. Mey published various articles on maritime and shipping in the press; these articles were also translated and published in foreign magazines. In 1925, Mey began compiling the navigation manual Eesti loots (Estonian Pilot), which was completed by the spring of 1927. It was the first Estonian-language book in this field. Mey died of heart disease a few days after the printing of Eesti loots at the Tallinn Military Hospital, and he was buried at Rahumäe Cemetery in Tallinn.

Family Johan Mey married Marie (Mari, Marri) Oengo (1873–1941), and they had five children. Their son Peter Friedrich Eustachius Mey (later Peeter Mei, 1893–1941) was a senior lieutenant and artillery officer of the Technical Department of the Naval Staff, and he died at the Ivdellag gulag in Russia. Among their daughters, Kristine Mei (1895–1969) was a sculptor and book illustrator, Lydia Mei (1896–1965) was a watercolorist, and Natalie Mei (1900–1975) was a painter and graphic artist. Another daughter, Helene (Leena) Mei (1898–1926), died of tuberculosis at a young age.

Worked examples

Example 1 — a first encounter with Johan Mey

Start with the simplest possible case. Write down what Johan Mey 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 Johan Mey 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 Johan Mey 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 Johan Mey

In research
Johan Mey 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 Johan Mey 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
Johan Mey is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1867 births, 1927 deaths, Estonian military officers, so understanding it makes those chapters shorter.
In everyday life
Look for Johan Mey 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.
