Louis Fraser

Louis Fraser 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 Louis Fraser rather than just read about it. In short: Louis Fraser (1810 – 1866) was a British zoologist and collector. In his early years, Fraser was curator of the Museum of the Zoological Society of London.

Key takeaways

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

Reference excerpt

Louis Fraser (1810 – 1866) was a British zoologist and collector. In his early years, Fraser was curator of the Museum of the Zoological Society of London. Little is known about Fraser's early life. He was born in 1810 and married Mary Ann Harrison on 17 February 1844. A son Oscar L. Fraser worked as an assistant in the Indian Museum at Calcutta around 1888. He worked for fourteen years at the museum of the Zoological Society of London. He worked with the anatomist Richard Owen on studies of the emu and rhea. He participated in the Niger expedition of 1841 as the African Civilization Society's scientist, with Allen and Thomson. He stayed on in Fernando Po and collected. Upon his return he became in charge of Lord Derby's collection at Knowsley Hall. In 1846 he was sent by Lord Derby to collect in north Africa. In 1848 he became conservator at Knowsley. He wrote Zoologica Typica, or figures of the new and rare animals and birds in the collection of the Zoological Society of London, a lavishly illustrated large-sized book, published in 1849. In this book he described many new species of birds. In 1850, Fraser was appointed Consul of Ouidah in the Kingdom of Dahomey. Around 1857–1859, he collected birds and mammals in Ecuador for Philip Lutley Sclater of the Zoological Society of London, and the year after in California. Upon his return to London, he opened a shop in Regent Street, London, selling exotic birds. The last years of his life he spent in America. Fraser wrote a Catalogue of the Knowsley Collections (1850) and described several new species including the Derbyan parakeet Psittacula derbiana named after his employer. A number of species and subspecies have been named in his honour, including Fraser's anole (Anolis fraseri), Fraser's ground snake (Liophis epinephelus fraseri), a centipede snake (Tantilla fraseri, a synonym of Tantilla melanocephala), Fraser's eagle-owl (Bubo poensis), Fraser's warbler (Myiothlypis fraseri), and Fraser's musk shrew (Crocidura poensis). Died at age 56.

Worked examples

Example 1 — a first encounter with Louis Fraser

Start with the simplest possible case. Write down what Louis Fraser 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 Louis Fraser 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 Louis Fraser 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 Louis Fraser

In research
Louis Fraser 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 Louis Fraser 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
Louis Fraser is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1819 births, 1866 deaths, 19th-century British zoologists, so understanding it makes those chapters shorter.
In everyday life
Look for Louis Fraser 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.
