Reference excerpt

Oleh Hornykiewicz (17 November 1926 – 26 May 2020) was an Austrian biochemist.

Life Oleh Hornykiewicz was born in 1926 in Sychów (now a district of Lviv), then in Poland (now Ukraine). In 1951, he received his M.D. degree from the University of Vienna and joined the faculty of his alma mater the same year and worked there ever since. He also served for twenty years as chairman of the Institute of Biochemical Pharmacology. In 1967, he began a long association with the University of Toronto in Canada and, in 1992, he was named professor emeritus at that institution. One of his seminal accomplishments was the discovery that Parkinson's disease was due to dopamine deficiency in the brain. He also played a key role in the development of L-dopa as a therapy for the disorder.

Awards 1972: Gairdner Foundation International Award 1979: Wolf Prize in Medicine, jointly with Roger Wolcott Sperry and Arvid Carlsson, "for opening a new approach in the control of Parkinson's disease by L-Dopa." 1993: Ludwig Wittgenstein Prize of the Austrian Science Foundation 1994: Schmiedeberg Medal of the German Society for Experimental and Clinical Pharmacology and Toxicology 2001: Bill Roth Medal 2008: Austrian Cross of Honour for Science and Art, 1st class 2010: Austrian Decoration for Science and Art 2014: Warren Alpert Foundation Prize

Worked examples

Example 1 — a first encounter with Oleh Hornykiewicz

Start with the simplest possible case. Write down what Oleh Hornykiewicz 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 Oleh Hornykiewicz 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 Oleh Hornykiewicz 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 Oleh Hornykiewicz

In research: Oleh Hornykiewicz 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 Oleh Hornykiewicz 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: Oleh Hornykiewicz is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1926 births, 2020 deaths, Academic staff of the University of Vienna, so understanding it makes those chapters shorter.
In everyday life: Look for Oleh Hornykiewicz 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.
