Reference excerpt

Paul Albert Antoine Bonét-Maury (7 February 1900, Paris, 6th arrondissement, to 17 April 1972, 13th arrondissement) was an early French judoka, president of the Fédération française de judo, and a French radiobiologist.

Biography Paul Bonét-Maury had twin careers, in both the sporting and medical fields.

Scientific career

Paul Bonet-Maury studied at the faculties of medicine, pharmacy and sciences of Paris. He obtained a doctorate in pharmacy in 1925. In October of the same year, he entered the Laboratoire Curie. Here he worked on the action of X-rays and radioactivity on living cells with Fernand Holweck and Antoine Lacassagne. He was successively Master of Research (1930–1965), then Honorary Research Master (1966), having been Professor at the National Institute of Nuclear Science and Technology at the CNRS (National Center for Scientific Research) since 1960. He was head of the Biophysics Laboratory of the Institute Alfred Fournier from 1941 to 1950. In 1950, he was appointed by Irène Joliot-Curie to create the Radium Institute's Radiation Protection Service. He was director of this department until 1962. Paul Bonet-Maury was an active trade unionist within l'Association des travailleurs scientifiques, (ATS) (the Association of Scientific Workers), of which he became secretary in 1946. From 1965 to 1966, he was president of la Société française de radioprotection. He invented the absolute photocolorimeter and the recording biophotometer.

Sporting career Paul Bonét-Maury practiced many sports such as football, rugby, boxing, skiing, swimming, sailing, and tennis, but it was in judo (and Ju-jitsu and wrestling) that his name is particularly remembered. In 1936, Paul Bonét-Maury met Jigoro Kano, the founder of judo, during the latter's trip to France. The same year saw the creation of the Jiu-jitsu Club of France. Paul Bonet-Maury became one of the two vice-presidents (the other being Moshe Feldenkrais, the founder of the club). In 1942, judo formed a specialized section of the French Wrestling Federation and Paul Bonet-Maury was elected president. In July 1944, Paul Bonét-Maury was appointed president of the French Wrestling Federation. In 1946, he founded the French Federation of Judo and Jiu-Jitsu (FFJJJ), which broke away from the French Wrestling Federation and later became the French Federation of Judo-Jujitsu, Kendo and Associated Disciplines. In 1947, he became a member of the brand new College of Black Belts, whose first elected president was Jean Andrivet. He was president of the FFJJJ until 1956. He was then secretary-general of the International Judo Federation, from which he resigned in 1971 for health reasons. Paul Bonet-Maury was the second Frenchman to win his black belt in judo. He reached 5th dan during his lifetime and was posthumously honored with 6th on September 14, 1975. He was interred at the cimetière du Père-Lachaise (44th division).

Worked examples

Example 1 — a first encounter with Paul Bonét-Maury

Start with the simplest possible case. Write down what Paul Bonét-Maury 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 Paul Bonét-Maury 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 Paul Bonét-Maury 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 Paul Bonét-Maury

In research: Paul Bonét-Maury 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 Paul Bonét-Maury 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: Paul Bonét-Maury is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1900 births, 1972 deaths, 20th-century French biologists, so understanding it makes those chapters shorter.
In everyday life: Look for Paul Bonét-Maury 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.
