Reference excerpt

Grigory Moiseevich Mairanovsky (Russian: Григо́рий Моисе́евич Майрано́вский, 1899, Batumi – 1964) was a Soviet biochemist and poison developer.

Career Mairanovsky was born to a Jewish family in Batumi in 1899. Mairanovsky was the head of several secret laboratories in the Bach Institute of Biochemistry in Moscow (1928–1935). As the head of Laboratory No. 1 (1938–1946), he initiated the secret poison program conducted by the NKVD. He used political prisoners for experiments with poisons. His classified PhD thesis defended in 1940 was entitled "Biological activity of the products of interaction of mustard gas with [human] skin tissues". Mairanovsky participated personally in political assassinations as a member of Pavel Sudoplatov's team in the 1940s, including assassination of Isaiah Oggins. He was arrested as a part of the doctors' plot in 1951, in connection with the case of Viktor Abakumov, and spent 10 years in prison. After his release, he headed a biochemical laboratory in Makhachkala, Dagestan ASSR.

Legacy He appears as a character in the Russian film Prediction by Eldar Ryazanov and has a tiny cameo mention in The Eighth Life, the prize-winning epic novel by Nino Haratischwili.

Worked examples

Example 1 — a first encounter with Grigory Mairanovsky

Start with the simplest possible case. Write down what Grigory Mairanovsky 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 Grigory Mairanovsky 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 Grigory Mairanovsky 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 Grigory Mairanovsky

In research: Grigory Mairanovsky 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 Grigory Mairanovsky 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: Grigory Mairanovsky is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1899 births, 1964 deaths, 20th-century Jews from Georgia (country), so understanding it makes those chapters shorter.
In everyday life: Look for Grigory Mairanovsky 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.
