Nikolay Timofeev-Ressovsky

Nikolay Timofeev-Ressovsky is a biology 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 Nikolay Timofeev-Ressovsky rather than just read about it. In short: Nikolay Vladimirovich Timofeev-Ressovsky (Russian: Николай Владимирович Тимофеев-Ресовский, romanized: Nikolay Vladimirovich Timofeyev-Resovskiy; 20 September [O.S. 7 September] 1900 – 28 March 1981) was a Soviet biologist who, in principle, was a senior scientist in Soviet programs of nuclear and, later in biological weapons. He conducted research in radiation genetics, experimental population genetics, and microev…

Key takeaways

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

Reference excerpt

Nikolay Vladimirovich Timofeev-Ressovsky (Russian: Николай Владимирович Тимофеев-Ресовский, romanized: Nikolay Vladimirovich Timofeyev-Resovskiy; 20 September [O.S. 7 September] 1900 – 28 March 1981) was a Soviet biologist who, in principle, was a senior scientist in Soviet programs of nuclear and, later in biological weapons. He conducted research in radiation genetics, experimental population genetics, and microevolution. His life was highlighted by scientific achievements in the face of severe personal hardship, including his imprisonment and working in secret scientific facilities of Soviet Gulag. Timofeev-Ressovsky was a descendant of the old Russian school of scientists, characterised by broad naturalistic views on the world, simultaneously combined with exact analysis of causes and consequences and establishment of elementary phenomena. He widely collaborated with physicists. Known for his influential personality, he was a talented story-teller and teacher. He is the author of the term 'genetic engineering'.

Education Nikolaj Vladimirovich Timofeev-Resovski, began his university education from 1916 to 1917 at the Moscow City People's University named after A. L. Shanyavskij. From 1917 to 1922, he studied at the First Moscow State University. The First World War and the consequences of the Russian Revolution of 1917 interrupted his education for periods of time. At the outbreak of the Russian Civil War, Timofeev-Resovskij was a follower of the anarchist Peter Kropotkin. In 1918, he volunteered to serve in a small anarchist cavalry unit, which was part of the Green army, i.e., they were neither supporters of the Bolshevik Red army nor the White army of General Anton Ivanovich Denikin. Eventually, in 1919, the anarchists joined the Red army. As a private in the 12th Red Army, Timofeev-Resovskij took part in the last battle of the Civil War in the Crimea on the Polish front. A paper trail of his education was swept away in the chaos of war. Timofeev-Resovskij abandoned his education without a scientific degree; he left formal education with only a gold medal. Even though he eventually became a recognized world-class scientist, he would later, as a requirement for employment, be required to complete his doctorate. He defended his doctoral dissertation in 1963 in Sverdlovsk, and he was awarded a Doctor of Science diploma in 1964.

Career

In Russia During the period 1920 to 1925, Timofeev-Resovskij was an instructor and researcher in Moscow. It was in this period that he met and married Elena Aleksandrovana Fidler (1898 – 1973), who was a student of the cytologist and biologist Nikolaj Konstantinovich Kol’tsov in Moscow; Elena became not only Timofeev-Resovskij's lifelong devoted companion but also his lifelong partner in research. Their eldest son, Dmitrij, was born on 11 September 1923. From 1920 to 1925, Timofeev-Resovskij was a biology instructor in the pre-Chekist district primary school in Moscow. From 1922 to 1925, he was a zoology instructor on the biotechnical faculty of the Moscow Practical (Applied) Institute. From 1921 to 1925, he did research at the Institute of Experimental Biology, of the Gosudarstvennyj Institut Narodnogo Zdravookhraneniya (GINZ, State Institute of Public Health), under the directorship of N. K. Kol’tsov. Some of his research at the Institute involved Drosophila. It was in a department headed by Sergei Sergeevich Chetverikov, the founder of population genetics and a colleague of Kol’tsov, that Timofeev-Resovskij started his genetics experiments. From 1924 to 1925, he was a research assistant in Kol’tsov's department of zoology at the Medical Pedagogical Institute in Moscow. In 1924, Timofeev-Resovskij began his publications in the field of phenogenetics. During the period 1923 to 1925, Oskar Vogt, an eminent psychiatrist and neurophysiologist, was a visiting scientist in Moscow; he was director of the Kaiser-Wilhelm Gesellschaft’s Institut für Hirnforschung (KWIH, Kaiser Wilhelm Institute for Brain Research) in Berlin. In part, he was looking to recruit researchers for the KWIH, especially in the relatively new field of genetics. In 1924, the Soviet government made an exchange agreement with Germany. The KWIH was invited to establish a laboratory for brain research in Moscow, which it did: Институт Мозга (Institut Mozga, Institute of the Brain). To reciprocate, the Soviets promised to help set up an experimental laboratory for genetics at the KWIH. Vogt had good relations with Nikolaj Aleksandrovich Semashko, People's Commissioner (Minister) of Health. It was Semashko and Kol’tsov who suggested Timofeev-Resovskij to Vogt. Thus, in the summer of 1925, Timofeev-Resovskij, his wife Elena and his colleague Sergei Romanovich Tsarapkin (Zarapkin), left Russia for an unspecified period of time in Germany, which lasted 20 years.

Worked examples

Example 1 — a first encounter with Nikolay Timofeev-Ressovsky

Start with the simplest possible case. Write down what Nikolay Timofeev-Ressovsky claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Nikolay Timofeev-Ressovsky 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 Nikolay Timofeev-Ressovsky 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 Nikolay Timofeev-Ressovsky

In research
Nikolay Timofeev-Ressovsky appears in biology 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 Nikolay Timofeev-Ressovsky 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
Nikolay Timofeev-Ressovsky is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1900 births, 1981 deaths, 20th-century Russian scientists, so understanding it makes those chapters shorter.
In everyday life
Look for Nikolay Timofeev-Ressovsky 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.
