John Eliot Howard

John Eliot Howard is a chemistry 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 Eliot Howard rather than just read about it. In short: John Eliot Howard (11 December 1807 – 22 November 1883) was an English chemist who conducted pioneering work collecting and analysing cinchona bark which led to significant influence in the quinine industry, particularly within 19th Century British-Indian Plantations. Howard was born in Plaistow, Essex, the son of Luke Howard a noted Quaker meteorologist and chemist.

Reference excerpt

John Eliot Howard (11 December 1807 – 22 November 1883) was an English chemist who conducted pioneering work collecting and analysing cinchona bark which led to significant influence in the quinine industry, particularly within 19th Century British-Indian Plantations. Howard was born in Plaistow, Essex, the son of Luke Howard a noted Quaker meteorologist and chemist. He worked at the family pharmaceutical manufacturing business of Howards and Sons. He was elected a Fellow of the Royal Society in June 1874. He was the author of scientific works including The Nueva Quinologia of Pavon (1862) and The Quinology of the East Indian Plantations (1869–1876), religious works including a commentary on the book of Hebrews and histories including The Island Of The Saints, about the Reformation in Ireland. His concern about issues of religion and science was reflected in his membership in two London organizations from 1872: the Victoria Institute, devoted to that subject to which he contributed thirteen papers, and to the Society of Biblical Archaeology, whose aim was to investigate antiquities of biblical lands.

Open Brethren Affiliation Howard was born into a Quaker family, and his eventual alignment with Brethren was a process of years. He apparently first came in contact with Brethren through B.W. Newton (also from a Quaker family). In 1838 Howard's association with Brethren led to his involvement in the assembly at the new Brook Street Meeting House in Tottenham, now Brook Street Chapel, which was founded in 1838–1839 by a number of other Christians including Howard's brother Robert; his father Luke (the 'namer of clouds' and 'father of meteorology') helped to finance the building of the chapel (a portrait of the father and son hangs in the National Portrait Gallery). It was with the opening of the Brook Street Chapel that Howard's transition to Brethren – and specifically "Open Brethren", as they came to be known – was complete.

Personal life Howard married Maria Crewdson on 9 September 1830 and the couple had nine children, including Joseph Howard, who was later Conservative MP for Tottenham. The family lived at Lord's Meade, Lordship Lane, Tottenham. Howard died in Edmonton, London, on 22 November 1883 at the age of 76, and was buried in Tottenham Cemetery with a . One of his grandchildren was the ornithologist, Henry Eliot Howard. The genus Howardia (a synonym of Pogonopus) of the Rubiaceae was dedicated to him.

Worked examples

Example 1 — a first encounter with John Eliot Howard

Start with the simplest possible case. Write down what John Eliot Howard claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, 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 Eliot Howard 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 Eliot Howard 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 Eliot Howard

In research: John Eliot Howard appears in chemistry 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 Eliot Howard 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 Eliot Howard is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1807 births, 1883 deaths, 19th-century English chemists, so understanding it makes those chapters shorter.
In everyday life: Look for John Eliot Howard 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.
