Jean de Carro

Jean de Carro 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 Jean de Carro rather than just read about it. In short: Jean de Carro (born in Geneva, August 8, 1770; died at Carlsbad, March 12, 1857) was a Republic of Geneva-born medical doctor who worked from Austria to promote vaccination against smallpox. Champion of vaccination Taking up his abode in Vienna in 1795, he became celebrated by his efforts in spreading Edward Jenner's system of vaccination as a protection against smallpox in Germany, Hungary, Poland, and Russia.

Key takeaways

Reference excerpt

Jean de Carro (born in Geneva, August 8, 1770; died at Carlsbad, March 12, 1857) was a Republic of Geneva-born medical doctor who worked from Austria to promote vaccination against smallpox.

Champion of vaccination Taking up his abode in Vienna in 1795, he became celebrated by his efforts in spreading Edward Jenner's system of vaccination as a protection against smallpox in Germany, Hungary, Poland, and Russia. In 1800 he sent a quantity of virus to Lord Elgin at Constantinople, together with a work of his own, translated into Turkish, on vaccination. The attempts of the English to introduce vaccination into India having been unsuccessful, because the virus had deteriorated on the way, Carro procured vaccine matter from cows of Lombardy..., and sent it to Dr. Harford at Baghdad. This retained all its strength, and was the means of introducing kinepox inoculation into India. The Hindus considered it to be derived from a sacred cow.

Works Observations et expériences sur l'inoculation de la vaccine (Vienna, 1801) Histoire de la vaccination en Turquie, en Grèce et aux Indes Orientales (1803) Carlsbad et ses eaux minérales (1827) Vingt-huit ans d'observation et d'expériences à Carlsbad (1853) For many years he published annually the Almanach de Carlsbad.

Worked examples

Example 1 — a first encounter with Jean de Carro

Start with the simplest possible case. Write down what Jean de Carro 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 Jean de Carro 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 Jean de Carro 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 Jean de Carro

In research: Jean de Carro 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 Jean de Carro 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: Jean de Carro is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1770 births, 1857 deaths, 19th-century people from the Republic of Geneva, so understanding it makes those chapters shorter.
In everyday life: Look for Jean de Carro 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.
