Reference excerpt

Jurriaan ten Doesschate (Utrecht, October 31, 1912 – Zeist, November 3, 1977) was a Dutch ophthalmologist and medical scientist, who specialized in physiological optics.

Biography The son of ophthalmologist and art historian Gezienus ten Doesschate and of linguist Amelia Hermina Henrietta Kortebosch, he attended the Municipal Gymnasium in Utrecht before studying medicine in the same city (1930–38). Despite (or perhaps because) he lost an eye in a youthful accident, ten Doesschate followed in the footsteps of his father. He established an ophthalmological practice in Zeist in 1942, the same year in which he obtained his doctorate in medicine with a dissertation on “Physiologisch-optische beschouwingen betreffende de visueele beoordeling van Röntgenphotogrammen” (Physiological-optical aspects of the visual assessment of radiographs). Two years earlier, he had married Anna Aleida Ameling, a fellow medical student at the University of Utrecht. Together they had four children. In 1949, he became chef de clinique of the Ooglijdersgasthuis (Netherlands Hospital for Eye Patients), which had been founded by Franciscus Cornelis Donders in 1858. Ten years later, he succeeded H.J.M. Weve as director of that hospital, a function that was coupled with a professorship in ophthalmology at the University of Utrecht medical faculty. In 1964-65, ten Doesschate was awarded the Netherlands Visiting Professorship at the University of Michigan in Ann Arbor, established in 1950. Here he collaborated with Mathew Alpern, a physiologist in the Vision Research Laboratory at the university's Medical School. Together they worked on the physiology of color vision and published a number of articles (see bibliography below). A meningioma, diagnosed and removed in 1970, severely reduced his vision and eventually necessitated his early retirement. He died in 1977 in a car accident.

Worked examples

Example 1 — a first encounter with Jurriaan ten Doesschate

Start with the simplest possible case. Write down what Jurriaan ten Doesschate 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 Jurriaan ten Doesschate 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 Jurriaan ten Doesschate 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 Jurriaan ten Doesschate

In research: Jurriaan ten Doesschate 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 Jurriaan ten Doesschate 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: Jurriaan ten Doesschate is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1912 births, 1977 deaths, 20th-century Dutch medical doctors, so understanding it makes those chapters shorter.
In everyday life: Look for Jurriaan ten Doesschate 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.
