Pierre Deniker

Pierre Deniker 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 Pierre Deniker rather than just read about it. In short: Pierre Deniker (16 February 1917, Paris – 17 August 1998, Paris) was a French psychiatrist who was involved, jointly with Jean Delay and J. M.

Key takeaways

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

Reference excerpt

Pierre Deniker (16 February 1917, Paris – 17 August 1998, Paris) was a French psychiatrist who was involved, jointly with Jean Delay and J. M. Harl, in the introduction of chlorpromazine (Thorazine), the first antipsychotic used in the treatment of schizophrenia, in the 1950s. Thorazine had been used in surgical procedures peri-operatively as an anti-nausea medication in France. Patients were noted to be less anxious and calmer. This observation eventually led Deniker to try chlorpromazine with patients who had schizophrenia, where he observed notable improvement in symptoms. The pharmaceutical company Smith-Kline had purchased the chlorpromazine rights from Rhone-Poulenc in France and had been marketing it as an anti-nausea medication. After Deniker's observations, they sought and received FDA approval in 1954 to market Thorazine for the treatment of schizophrenia. During the Second World War, Deniker and Professor Pasteur Vallery-Radot took an active part in French Resistance. In 1943, they enrolled one hundred young medical students of Paris to make a Center of First Aid Workers. They wore military uniforms and took care of the civilian population after the bombing of towns by the Germans. They also treated people returning from Germany, especially the deportees and the prisoners of war.

Worked examples

Example 1 — a first encounter with Pierre Deniker

Start with the simplest possible case. Write down what Pierre Deniker 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 Pierre Deniker 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 Pierre Deniker 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 Pierre Deniker

In research: Pierre Deniker 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 Pierre Deniker 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: Pierre Deniker is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1917 births, 1998 deaths, 20th-century French medical doctors, so understanding it makes those chapters shorter.
In everyday life: Look for Pierre Deniker 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.
