This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Lars Ernster rather than just read about it. In short: Lars Ernster (Hungarian: Ernster László; 4 May 1920 – 4 November 1998) was a professor of biochemistry, and a member of the Board of the Nobel Foundation. Biography Lars Ernster was born in Hungary and came to Sweden in 1946.

Key takeaways

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

Reference excerpt

Lars Ernster (Hungarian: Ernster László; 4 May 1920 – 4 November 1998) was a professor of biochemistry, and a member of the Board of the Nobel Foundation.

Biography Lars Ernster was born in Hungary and came to Sweden in 1946. He played a prominent role in the scientific community. He took his PhD degree at the Stockholm University in 1956. Until 1967 he was the head of the division for Physiological Chemistry at the Wenner-Gren Institute (Axel Wenner-Gren). From 1967 to 1986 he was a professor of biochemistry. He was a member of the Royal Swedish Academy of Sciences from 1974. He was elected a foreign member of the Royal Netherlands Academy of Arts and Sciences in 1987. "The burning interest in science, the desire to get to the truth of the matter, the intense but courteous questioning and, above all, his charming and warm smile" as seen by a friend, colleague, fellow-European and competitor Edward Slater.

Nobel Foundation Lars Ernster was a member of the Board of the Nobel Foundation 1977–1988. 1978 Presentation Speech [1] by Professor Lars Ernster of the Royal Swedish Academy of Sciences, The Nobel Prize in Chemistry 1978 Your Majesties, Your Royal Highnesses, Ladies and Gentlemen, The discoveries for which Peter Mitchell has been awarded this year's Nobel Prize for Chemistry relate to a field of biochemistry often referred to in recent years as bioenergetics, which is the study of those chemical processes responsible for supplying energy to living cells.

All living organisms need energy to survive. Muscular work, thought processes, growth, and reproduction are all examples of biological activities that require energy. We know today that every living cell is capable, by means of suitable catalysts, of deriving energy from its environment, converting this energy into a biologically useful chemical form, and utilizing it for various energy-requiring processes.

Lars Ernster rescued 8 January 1945 During World War II, Lars Ernster, Edith Ernster and Jacob Steiner lived in the office of the Swedish Embassy in Budapest Üllöi ut 2-4. During the night of 8 January 1945, all inhabitants were dragged away by an Arrow Cross Party executing brigade of the city commander near the banks of the Danube. At midnight, 20 policemen with drawn bayonets broke into the Arrow Cross house and rescued everyone. [3]

Edith Ernster remembers Edith Ernster, who lived through that time, recalls: "It seemed so strange - this country of super-aryans, the Swedes, taking us under their wings. Often, when an Orthodox Jew went by, in his hat, beard and sidelocks, we'd say, 'Look, there goes another Swede." A special department was created in the Swedish embassy in Budapest with Raoul Wallenberg as its head. It was staffed primarily with Jewish volunteers. Initially, there were 250 workers; later, he had about 400 people working around the clock. Wallenberg seemed to sleep no more than an hour or two a night, and then it was wherever he happened to be working. He was everywhere.

Worked examples

Example 1 — a first encounter with Lars Ernster

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

In research
Lars Ernster appears in chemistry 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 Lars Ernster 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
Lars Ernster is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1920 births, 1998 deaths, Hungarian Jews, so understanding it makes those chapters shorter.
In everyday life
Look for Lars Ernster 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.
