Trijntje Keever

Trijntje Keever 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 Trijntje Keever rather than just read about it. In short: Trijntje Cornelisdochter Keever (10 or 16 April 1616 – 2 July 1633), nicknamed De Groote Meid ('The Tall Girl'), was a Dutchwoman alleged to be the tallest female in recorded history, standing 9 Amsterdam feet, an archaic measurement used in the Netherlands which measured 1 foot as 28.313 cm or 0.929 feet. In modern measurements, she measured 2.60 metres (8 ft 6.75 in) tall at the time of her death at age seventeen.

Reference excerpt

Trijntje Cornelisdochter Keever (10 or 16 April 1616 – 2 July 1633), nicknamed De Groote Meid ('The Tall Girl'), was a Dutchwoman alleged to be the tallest female in recorded history, standing 9 Amsterdam feet, an archaic measurement used in the Netherlands which measured 1 foot as 28.313 cm or 0.929 feet. In modern measurements, she measured 2.60 metres (8 ft 6.75 in) tall at the time of her death at age seventeen.

Biography Trijntje Keever was the daughter of Cornelis Keever and Anna Pouwels. Cornelis was a Dutch skipper and Anna was his maid; he married her on May 24, 1605. Trijntje was born on April 10 or 16, 1616, in Edam. Keever's parents took her to carnivals to earn some money by letting people see her. Trijntje first received public attention when she was nine years old and had reached the height of 2 metres (6 ft 7 in). A royal company consisting of the Bohemian king Frederick V, Elector Palatine, his wife Elizabeth of Bohemia and the princess Amalia of Solms-Braunfels, living in The Hague at the time, visited her, curious about the "nine-year-old girl taller than every man in Europe". Keever died of cancer at the age of 17 in Ter Veen. She was buried on 7 July 1633 in Edam, her town of birth. Her epitaph is said to have read, Trijntje Crelis groote meidt oudt 17 jaer, or, in English: “Trijntje Crelis, tall girl, 17 years of age”. In the townhall of Edam is a lifesize painting by an unknown artist portraying Keever in civilian clothes with a belt, holding at her right a keyring and at her left a pincushion and a sheath with a knife, fork, and spoon. Her original shoes are also on display. If there were a size for the shoes, they would be European size 54 (36 cm or 14 inches long).

Worked examples

Example 1 — a first encounter with Trijntje Keever

Start with the simplest possible case. Write down what Trijntje Keever 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 Trijntje Keever 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 Trijntje Keever 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 Trijntje Keever

In research: Trijntje Keever 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 Trijntje Keever 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: Trijntje Keever is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1616 births, 1633 deaths, 17th-century Dutch people, so understanding it makes those chapters shorter.
In everyday life: Look for Trijntje Keever 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.
