Henri Antoine Jacques

Henri Antoine Jacques 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 Henri Antoine Jacques rather than just read about it. In short: Henri Antoine Jacques (1782 Chelles, Seine-et-Marne – 1866) was a French nurseryman specialising in roses, and noted for having introduced the Bourbon Group of roses from Île Bourbon to France. It was illustrated by Pierre-Joseph Redouté (1759-1840) in his work "Les Roses".

Key takeaways

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

Reference excerpt

Henri Antoine Jacques (1782 Chelles, Seine-et-Marne – 1866) was a French nurseryman specialising in roses, and noted for having introduced the Bourbon Group of roses from Île Bourbon to France. It was illustrated by Pierre-Joseph Redouté (1759-1840) in his work "Les Roses". He was born into a family of gardeners. On leaving the army, he worked as apprentice gardener at the Grand Trianon near Versailles, where his acumen caught the eye of Napoleon and whom Jacques told that his goal was to become head gardener on one of Napoleon's estates. Eventually in 1818 he became head gardener to the Duke of Orleans, later to become King Louis Philippe I, at the Château de Neuilly on the banks of the Seine near Paris, as well as Monceau on the outskirts of Paris, and Le Raincy near Chelles. These three estates totalled several thousand acres, earning him a salary, with free housing, clothing, food, horses, etc. for his wife and family, of some FFr8,000 a year, increasing to about FFr14,000 by 1835. When Louis Philippe was forced to abdicate in 1848 the Châteaux of Neuilly and Villiers were destroyed. The collaboration between King Louis Philippe I and Jacques, both great lovers of plants, led to a number of new plant varieties, in particular several new rambling roses. These stemmed in part from Rosa sempervirens, introduced from 1826 onwards and its varieties still popular today because of an ability to climb over arches, trellises and walls, producing a profusion of nodding flowers. Two of Jacques’ roses have received The Royal Horticultural Society’s Award of Garden Merit. Other varieties which remained popular were the 1828 ‘Félicité-Perpétue’ - Perpetua and Felicity were two Christian women martyred for their faith in Carthage in AD203. Jacques was one of the founding members of the "Horticultural Society of Paris", created 11 June 1827 which became, in 1885, the National Horticultural Society of France. The sempervirens hybrids were named mainly for members of the King's family – "Adélaide d’Orléans" (after his sister), "Princesse Louise" (after his eldest daughter, the later Queen of Belgium), "Princesse Marie", (his second daughter). The laboratory of Micromolecular Biology and Phytochemistry of the Université Claude Bernard in Lyon has studied the genetic provenance of some of the most celebrated of Antoine Jacques’ roses, in an attempt to reveal their parentage. Antoine Jacques, besides being a zealous and gifted gardener, was acquainted with the writings of eminent botanists from all over the world. He published a number of catalogues listing the plants in the Royal gardens, as well as a four-volume Flora of the plants of Europe in collaboration with the botanist François Hérincq, "Manuel général des plantes arbres et arbustes: comprenant leur origine, description, culture, leur application aux jardins d'agrément, à l'agriculture, aux forêts, aux usages domestiques, aux arts et à l'industrie, et classés selon la méthode de Decandolle". He also published monographs on conifers, and on the Chinese cabbage or Pe-tsai.

Worked examples

Example 1 — a first encounter with Henri Antoine Jacques

Start with the simplest possible case. Write down what Henri Antoine Jacques 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 Henri Antoine Jacques 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 Henri Antoine Jacques 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 Henri Antoine Jacques

In research
Henri Antoine Jacques 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 Henri Antoine Jacques 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
Henri Antoine Jacques is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1782 births, 1866 deaths, 19th-century French botanists, so understanding it makes those chapters shorter.
In everyday life
Look for Henri Antoine Jacques 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.
