Jabez Hogg

Jabez Hogg 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 Jabez Hogg rather than just read about it. In short: Jabez Hogg (4 April 1817 – 23 April 1899) was an English ophthalmic surgeon and early photographer. A 1843 daguerreotype of him taking someone's photo is the earliest known photo of a photographer at work.

Key takeaways

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

Reference excerpt

Jabez Hogg (4 April 1817 – 23 April 1899) was an English ophthalmic surgeon and early photographer. A 1843 daguerreotype of him taking someone's photo is the earliest known photo of a photographer at work.

Biography Hogg was the youngest son of James Hogg and Martha, his wife, was born at Chatham, where his father was employed in the royal dockyard, on 4 April 1817. He was educated at Rochester grammar school, and in 1832 was apprenticed for five years to a medical practitioner. In 1843 he published a 'Manual of Photography,' which brought him to the notice of the proprietors of the 'Illustrated London News.' He joined the staff of this periodical, and from 1850 to 1866 he acted as editor of a series of illustrated educational works published by Mr. Herbert Ingram. In 1846 he was sub-editor of the 'Illuminated Magazine,' to which Hablot K. Browne and John Leech both contributed, and he edited the 'Illustrated London Almanack' for fifty-one years. Hogg entered as a student at the Hunterian School of Medicine and at Charing Cross Hospital in 1845, though he was not admitted a member of the Royal College of Surgeons of England until 1850. By the advice of George James Guthrie, he devoted himself more particularly to the study of diseases of the eye, and he soon became proficient in the use of the ophthalmoscope, then newly introduced. On 1 February 1855, he was appointed at the Royal Westminster Ophthalmic Hospital as personal assistant to Guthrie, the founder of the hospital, and here he was elected to the office of surgeon on 2 February 1871, a position he resigned under an age limit on 7 June 1877. He was also an ophthalmic surgeon at the Hospital for Women and Children in the Waterloo Bridge Road and to the masonic charities. He was a vice-president of the Medical Society of London in 1851–2, and was elected a fellow of the Linnean Society in 1866. He served as honorary secretary of the Royal Microscopical Society from 1867 to 1872, and he was first president of the Medical Microscopical Society. He was a prominent freemason, both in the craft and arch degrees. He died on 23 April 1899 and is buried in Kensal Green cemetery. He married, in 1841, Mary Ann, a daughter of Captain Davis of the Indian navy, and in 1859 the youngest daughter of Captain James Read. Hogg's works were:

Worked examples

Example 1 — a first encounter with Jabez Hogg

Start with the simplest possible case. Write down what Jabez Hogg 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 Jabez Hogg 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 Jabez Hogg 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 Jabez Hogg

In research
Jabez Hogg 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 Jabez Hogg 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
Jabez Hogg is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1817 births, 1899 deaths, 19th-century English male photographers, so understanding it makes those chapters shorter.
In everyday life
Look for Jabez Hogg 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.
