John Nevil Maskelyne

John Nevil Maskelyne 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 John Nevil Maskelyne rather than just read about it. In short: John Nevil Maskelyne (22 December 1839 – 18 May 1917) was an English stage magician and inventor of the pay toilet, along with other Victorian-era devices. He worked with magicians George Alfred Cooke and David Devant, and many of his illusions are still performed today.

Key takeaways

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

Reference excerpt

John Nevil Maskelyne (22 December 1839 – 18 May 1917) was an English stage magician and inventor of the pay toilet, along with other Victorian-era devices. He worked with magicians George Alfred Cooke and David Devant, and many of his illusions are still performed today. His book Sharps and Flats: A Complete Revelation of the Secrets of Cheating at Games of Chance and Skill is considered a classic overview of card sharp practices. In 1914 he founded the Occult Committee, a group to "investigate claims to supernatural power and to expose fraud".

Early life Maskelyne was born on 22 December 1839 at Cheltenham, Gloucestershire, England to John Nevil Maskelyne (1800–1875), a saddler, and his wife Harriet (1812-1871), née Brunsdon. He was baptized at St Lawrence, Swindon, near, Cheltenham, on 26 January 1840. He trained as a watchmaker. Maskelyne claimed to be a descendant of Nevil Maskelyne (1732–1811), the Astronomer Royal; although some sources repeat this, other recent biographical accounts establish otherwise.

Career Maskelyne became interested in conjuring after watching a stage performance at his local Town Hall by the fraudulent American spiritualists the Davenport brothers. He saw how the Davenports' spirit cabinet illusion worked, and stated to the audience in the theatre that he could recreate their act using no supernatural methods. With the help of a friend, cabinet maker George Alfred Cooke, he built a version of the gigantic cabinet. Together, they revealed the Davenport Brothers' trickery to the public at a show in Cheltenham in June 1865, sponsored by the 10th Cotswold Rifle Corps to which they belonged. In addition to the pseudo-spiritualist phenomena of the Davenports, they added comedy illusions which included the transformation of Maskelyne and Cooke into an "unprotected female" and a gorilla. Inspired by the acclaim they received for their clever exposure of the deception, the two men repeated their show several times. Following their local success, they branched out taking their show to nearby towns. Encouraged by their results, they decided to become professional magicians and organised tours, building on their initial routines and expanding their programme. At first they struggled to make ends meet but they were saved by a young and relatively inexperienced theatrical agent named William Morton, who saw their show in Liverpool and offered to finance a tour. He engaged them at a weekly wage of £4 10s for Maskelyne and his wife, and 50 shillings for Cooke. Morton ran them round the country for two years, ending at The Crystal Palace for several weeks. He then secured for them the Egyptian Hall in Piccadilly, renovated it, put in a new stage and opened at the end of 1873. Morton remained their manager for 20 years. He helped them to become firmly established on the national stage, including such marathon theatrical engagements as their famous 31-year tenancy at the Egyptian Hall, which ended in 1905 when the Hall was demolished. During his performances, Maskelyne often incorporated his illusions into short plays. His performances at the Egyptian Hall influenced the magician and filmmaker Georges Méliès, whose short films incorporated special effects and illusions into short narratives.

Further achievements Maskelyne and Cooke invented many illusions still performed today. Maskelyne was adept at working out the principles of illusions, one of his best-known being levitation. Levitation is commonly but incorrectly said to be Jean Eugène Robert-Houdin's creation, but it was Maskelyne's. The confusion arises because Robert-Houdin invented the illusion "La Suspension Ethéréenne" (aka the "Broom Suspension"). Levitation is also credited to American magician Harry Kellar, who in fact stole the illusion by bribing Maskelyne's technician, Paul Valadon. On Cooke's death in February 1905, Maskelyne started a partnership with David Devant. Devant first joined Maskelyne's team in 1893 when he auditioned as a replacement for Charles Morritt, a conjurer and inventor who worked with Maskelyne at the Egyptian Hall but who left to set up his own show. In 1894, Maskelyne wrote the book Sharps and Flats: A Complete Revelation of the Secrets of Cheating at Games of Chance and Skill. It became an instant hit, and to this day is considered a classic gambling book. It was the first detailed revelation of the secrets of cardsharps. Other authors prior to Maskelyne had written about crooked gambling, but never had anyone published a work with in-depth, detailed explanations of the secrets of crooked gambling. The first edition was published in London and New York. Later, when it entered the public domain, the Gambler's Book Club of Las Vegas published the first reprint. It is now also available online in the form of an annotated website. Maskelyne wrote several books, but Sharps and Flats is by far his most important and best known literary work.

Worked examples

Example 1 — a first encounter with John Nevil Maskelyne

Start with the simplest possible case. Write down what John Nevil Maskelyne 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 John Nevil Maskelyne 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 John Nevil Maskelyne 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 John Nevil Maskelyne

In research
John Nevil Maskelyne 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 John Nevil Maskelyne 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
John Nevil Maskelyne is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1839 births, 1917 deaths, Anomalistic psychology, so understanding it makes those chapters shorter.
In everyday life
Look for John Nevil Maskelyne 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.
