Reinhold Duschka

Reinhold Duschka 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 Reinhold Duschka rather than just read about it. In short: Reinhold Duschka (1900-1993) was an Austrian iron worker who from 1939 until April 1945 hid the Jewish Chemist Regina Kraus and her 10-year-old daughter Lucia (later Lucia Heilman) from the National Socialist regime. In 1990, he was awarded the title of Righteous Among the Nations by Yad Vashem for his actions.

Key takeaways

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

Reference excerpt

Reinhold Duschka (1900-1993) was an Austrian iron worker who from 1939 until April 1945 hid the Jewish Chemist Regina Kraus and her 10-year-old daughter Lucia (later Lucia Heilman) from the National Socialist regime. In 1990, he was awarded the title of Righteous Among the Nations by Yad Vashem for his actions.

Life

In the 1920s, Duschka worked as an iron worker out of a workshop in Mollardgasse in the 6th district of Vienna, Austria. He became friendly with Rudi Kraus and Regine Hildebrandt, who married and had a daughter in 1929, called Lucia. Shortly after the Anschluss in 1938, Regina and her daughter Lucia attempted to follow her husband to Iran, where he had been working as an engineer. They were unable to obtain transit papers, nor did they have the money for passage by ship. In 1939, their apartment was confiscated by the National Socialist regime as part of widespread confiscations of Jewish property. Duschka offered to shelter them in his workshop in full knowledge that he was putting his own life in danger. He cared for the two fugitives throughout the war, regularly providing food and clothing which he bought on the black market. Duschka also managed to provide school books for Lucia, so her mother could give her lessons. By observing Duschka, Regine and Lucia learnt how to work with metal and assisted him with his daily tasks. In 1944, the workshop was heavily damaged in an Allied bombing raid. Regina and Lucia were lucky to survive but had to leave the building. Duschka found them alternative accommodation in a summer house in Hütteldorf, where they stayed hidden until the end of the war. He explained to his neighbours that they were relatives from Germany. After the war, Duschka rebuilt his workshop and continued his work there until his retirement. On 7 March 1990 he was awarded the honorific "Righteous Among the Nations". In April 2013 a sign commemorating Duschka's actions was installed on the facade. In 2018, Austrian novelist Erich Hackl published the novel Am Seil based on Duschka's story.

Worked examples

Example 1 — a first encounter with Reinhold Duschka

Start with the simplest possible case. Write down what Reinhold Duschka 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 Reinhold Duschka 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 Reinhold Duschka 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 Reinhold Duschka

In research: Reinhold Duschka 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 Reinhold Duschka 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: Reinhold Duschka is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1900 births, 1993 deaths, Austrian Righteous Among the Nations, so understanding it makes those chapters shorter.
In everyday life: Look for Reinhold Duschka 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.
