James Dwyer McGee

James Dwyer McGee is a physics 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 James Dwyer McGee rather than just read about it. In short: James Dwyer McGee (17 December 1903 – 28 February 1987) was an Australian scientist and photoelectronics inventor, who worked for many years at EMI in west London, largely developing the first television camera. Early life He was born in Queanbeyan, New South Wales in Australia, the sixth of seven children.

Key takeaways

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

Reference excerpt

James Dwyer McGee (17 December 1903 – 28 February 1987) was an Australian scientist and photoelectronics inventor, who worked for many years at EMI in west London, largely developing the first television camera.

Early life He was born in Queanbeyan, New South Wales in Australia, the sixth of seven children. His father was Francis Joseph McGee (8 July 1866 – 13 February 1950). He attended St Patrick's College, Goulburn. He studied Physics and Mathematics at university. In 1928 he won a 1851 Research Fellowship to study in the UK, and he gained a PhD in Nuclear Physics from Clare College, Cambridge in November 1931.

Career

EMI He moved to EMI in January 1932. J.D. McGee worked with the first technology of television, and invented the BBC's first television cameras with William Francis Tedham (1902–2000) at EMI's Central Research Laboratories in Middlesex. Tedham and McGee submitted their first patent on 12 May 1932. He worked at EMI with Hans Gerhard Lubszyński (31 August 1904-1997) and Sydney Rodda. He featured in a BBC1 documentary programme at 9.30 pm on Thursday 3 November 1966 entitled The Discovery of Television.

University He was invited to the Department of Physics at Imperial College London in 1954 by Patrick Blackett, where he became Professor of Applied Physics. He researched image intensifiers, photomultipliers, and secondary emission. In his academic staff was Leonard Mandel (until 1964). He retired in 1971. He left the university in 1980 and moved to Australia.

Lectures He gave a lecture at the Royal Society of Arts in February 1952, about the future of television, entitled Television Technique as an Aid to Observation. He gave the RTS Fleming Lecture on 31 October 1964 and 19 January 1956. On 14 February 1957 he gave a lecture to the British Kinematograph, Sound and Television Society (BKS) entitled Photo-electronic aids to Photography.

Personal life He was given the OBE in the 1952 New Year Honours, and the FRS on 17 March 1966. He lived in west London at 56 Corringway, south of Hanger Lane tube station, east of the North Circular Road. In 1939, he was living slightly further south on Creffield Road, at the junction with Inglis Road. In the mid-1930s, he lived at 9 Kingfield Road, the other side of the North Circular Road.

Worked examples

Example 1 — a first encounter with James Dwyer McGee

Start with the simplest possible case. Write down what James Dwyer McGee claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 James Dwyer McGee 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 James Dwyer McGee 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 James Dwyer McGee

In research
James Dwyer McGee appears in physics 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 James Dwyer McGee 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
James Dwyer McGee is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1903 births, 1987 deaths, Academics of Imperial College London, so understanding it makes those chapters shorter.
In everyday life
Look for James Dwyer McGee 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.
