Pierre Douzou

Pierre Douzou is a physics 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 Douzou rather than just read about it. In short: Pierre Douzou (August 25, 1926 – June 9, 2000) was a French biochemist and a pioneer in cryobiology who led parallel scientific careers in both civic and military institutions. He founded the field of cryoenzymology and developed antifreeze solvents, which found particularly use in agronomy.

Key takeaways

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

Reference excerpt

Pierre Douzou (August 25, 1926 – June 9, 2000) was a French biochemist and a pioneer in cryobiology who led parallel scientific careers in both civic and military institutions. He founded the field of cryoenzymology and developed antifreeze solvents, which found particularly use in agronomy. Douzou is recognized worldwide for his work in the physical chemistry of biological reactions at low temperatures. Besides his scientific research, he was a promoter of original research at the intersection between the inanimate and the living and participated in France's scientific policymaking for several decades.

Education and career Douzou was born in Millau as the son of the glover Gaston Douzou. After studying at the Rodez high school, Douzou studied pharmacy at the École de santé des armées in Toulon in 1951 and later in Lyon. In 1953, Douzou entered the University of Paris and conducted research at the Radium institute (later Curie Institute) under the supervision of Moïse Haïssinsky. He completed his doctoral thesis in 1958 and was appointed a lecturer at the Muséum national d'histoire naturelle by Charles Sadron in the same year. During this period, Douzou was also a biologist since 1959 and an associate researcher (maître de recherche) at the French Armed Forces Health Service in 1965. This period saw him working at the Val-de-Grâce army hospital in Paris. Douzou left the museum in 1966 and joined the Institut de biologie physico-chimique, where he was starting to establish the biospectroscopy department. Douzou worked at the École pratique des hautes études from 1971 to 1977 as the director of the laboratory for macromolecular biology. In 1974, Douzou joined INSERM and established the research unit 128, cryobiology applied to the study of metabolism (Cryobiologie appliquée à l'étude de métabolismes), from 1974 to 1980, which was based in Montpellier. In 1977, he was also director of the Institut de biologie physico-chimique in Paris and was appointed a professor at the Muséum national d'histoire naturelle to succeed Charles Sadron, a position he held until his retirement in 1995. His monograph on cryobiochemistry, published in 1977, summarizes the efforts made in along with colleagues such as Claude Balny and Gaston Hui Bon Hoa. From 1987 to 1994, Douzou was director of the research unit on Molecular and cellular biology at low temperatures at the Curie Institute in Paris. From 1989 to 1991, Douzou was also director of INRA. From 1985 to 1993, Douzou, along with Gilbert Durand and Philippe Kourilsky, coordinated the national biotechnology program at the Ministry of Research and Technology (ministère de la Recherche et de la Technologie).

Worked examples

Example 1 — a first encounter with Pierre Douzou

Start with the simplest possible case. Write down what Pierre Douzou claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 Douzou 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 Douzou 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 Douzou

In research
Pierre Douzou appears in physics 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 Douzou 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 Douzou is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1926 births, 2000 deaths, 20th-century French biologists, so understanding it makes those chapters shorter.
In everyday life
Look for Pierre Douzou 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.

Pierre Douzou (August 25, 1926 – June 9, 2000) was a French biochemist and a pioneer in cryobiology who led parallel scientific careers in both civic and military institutions. He founded the field of cryoenzymology and developed antifreeze solvents, which found particularly use in agronomy.

Why does Pierre Douzou matter?

Because it connects several physics ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Pierre Douzou?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
