Rodolfo Robles

Rodolfo Robles is a astronomy 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 Rodolfo Robles rather than just read about it. In short: Rodolfo Robles (January 14, 1878 – November 8, 1939) was a Guatemalan physician and philanthropist. In 1915, he was the first to describe onchocerciasis in Latin America, which was known and widespread on the African continent, with the first description of the adult worms made there in 1890 by Sir Patrick Manson.

Key takeaways

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

Reference excerpt

Rodolfo Robles (January 14, 1878 – November 8, 1939) was a Guatemalan physician and philanthropist. In 1915, he was the first to describe onchocerciasis in Latin America, which was known and widespread on the African continent, with the first description of the adult worms made there in 1890 by Sir Patrick Manson. Robles was the first person to describe the etiology of the disease, correctly attributing it to infection with Onchocerca volvulus parasites. He discerned the etiology from clinical observations among coffee plantation workers in Guatemala, extracting the parasitic worm from a nodule on a child's face. The disease was later referred to as "Roble's disease" in his honor. In the 1930s, Robles also played a role in establishing the first public health campaigns to address onchocerciasis in the Central Endemic Zone of Guatemala, which involved sending teams to endemic areas to provide surgical services and perform nodulectomies.

Biography Rodolfo Robles was born in Quetzaltenango, Guatemala. As a young man, he was sent to school in the United States, returning to complete high school at the Instituto Nacional para Varones de Occidente (INVO) in 1894. He completed pre-university studies at Rouen, in France, before studying medicine in Paris and earning his degree from the University of Paris in 1904. He performed research at the Pasteur Institute in Paris, where he obtained the Ordre national de la Légion d'honneur (French: "National Order of the Legion of Honour") in the degree of Grand Officier (Grand Officer). Robles married Julia Isabel Herrera Dorión in 1914, and had one child, Rodolfo Robles Herrera, born in Paris in 1928. He served as a professor in the Faculty of Medical Sciences for many years.

Honors and tributes Robles has been honored in Guatemala and Mexico with many schools and hospitals named in his honor, including a hospital in his hometown of Quetzaltenango as well as a hospital focused on eye and ear health in Guatemala City. In 1955, the Order of Rodolfo Robles was established as award to recognize physicians for outstanding service in the field of public health. A statue of his likeness can be found outside the old Faculty of Medical Sciences at the Universidad de San Carlos de Guatemala. A bridge over the Suchiate River, which forms the border between the Mexican state of Chiapas and the Guatemalan department of San Marcos, has been named Puente Rodolfo Robles in his honor.

Worked examples

Example 1 — a first encounter with Rodolfo Robles

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

In research: Rodolfo Robles appears in astronomy 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 Rodolfo Robles 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: Rodolfo Robles is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1878 births, 1939 deaths, Epidemiologists, so understanding it makes those chapters shorter.
In everyday life: Look for Rodolfo Robles 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.
