Key takeaways

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

Reference excerpt

Samuel Stevens (11 March 1817 – 29 August 1899) was an entomological collector and a natural history agent in London. He was one of the founding members of the Entomological Society of London. He sold specimens from collectors that he sponsored including Alfred Russel Wallace and Henry Walter Bates.

Life and work

Stevens was born in Kennington to John (c.1772–1836) and Augusta Crace. With a father interested in arts Samuel also sought to train as an artist. He received a medal from the Royal Society of Arts for some pencil sketches at the age of thirteen but illness prevented him from pursuing art. He partnered with his brother John Crace Stevens (1809-1859) from 1840 in Stevens' Auction Rooms on 38, King Street. The auction house, known as Covent Garden auction house founded in 1760 was joined in by John Crace as a partner in 1831 and the company name was changed to J.C. Stevens' in 1834. Both the Stevens brothers was a keen entomological collectors for much of their life but were not very scientifically inclined. Samuel left the auction company in 1848 and started his own natural history agency from his shop at 24 Bloomsbury Street, London which ran until 1867 when he sold it to Edmond Thomas Higgins. He briefly managed the auction company after the death of his brother in 1859 until his nephews could take over. Stevens was an agent who sponsored specimen collection and two of his best known collectors were Alfred Russel Wallace and Henry Walter Bates. He supported their joint collecting expedition to the Amazon and then Wallace's journeys in the Malay Archipelago by buying their specimens, displaying them to learned societies and selling them to collectors. Their sales included the collections of 40000 insects made by Adrian Hardy Haworth, orchids, and the menagerie of Lord Derby. also supported the botanical collector Robert William Plant (1818-1858). For many years, Stevens lived with his mother Augusta, who died in 1868. Stevens married late in life to Francis Wood in 1874. After 1876 he retired to live at Loanda, Beulah Hill, Upper Norwood taking an interest in his insect collections, fishing, and water-colour painting. After his death, his collections were sold off in auctions by his nephew J.S. Stevens.

Stevens was a member of the Linnean Society from 1850. Stevens is remembered in the specific name of the Jamaican snail, Petitia stevensiana (now Fadyenia stevensiana), named by Edward Chitty in 1857 “in compliment to the naturalist’s universal friend, S. Stevens, Esq., Bloomsbury Street, London.”

Worked examples

Example 1 — a first encounter with Samuel Stevens (naturalist)

Start with the simplest possible case. Write down what Samuel Stevens (naturalist) 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 Samuel Stevens (naturalist) 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 Samuel Stevens (naturalist) 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 Samuel Stevens (naturalist)

In research
Samuel Stevens (naturalist) 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 Samuel Stevens (naturalist) 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
Samuel Stevens (naturalist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1817 births, 1899 deaths, Fellows of the Linnean Society of London, so understanding it makes those chapters shorter.
In everyday life
Look for Samuel Stevens (naturalist) 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.
