Reference excerpt

George Jeffrey (1853 – 26 April 1942) was a Scots-born wool technologist, who developed the art or science of wool classing in South Australia through teaching and lecturing, leading to better returns to the grower and bolstering the country's reputation for high quality wools.

History Jeffrey was born in Scotland and served his apprenticeship as a wool sorter at Hawick. He left for Australia and for a time worked in wool scouring and fellmongers' factories, but the work was too strenuous for his constitution and he returned to the trade of wool sorter and buyer in Melbourne.

Lobethal

In 1880 The insolvent Lobethal Wool and Tweed Company was offered for sale by auction, unreserved. It was purchased in 1890 by the South Australian Woollen Factory Company, Ltd (a local syndicate) and Robert Redpath appointed manager. By 1892 Jeffrey was working for the company as head wool classer Later known as Onkaparinga Woollen Company, it became a major industry, and its pure wool rugs sold Australia-wide.

Teaching

In 1897 he appealed to the Council of the School of Mines, through its president Langdon Bonython, to include woolclassing in the curriculum. Bonython agreed that if six students enrolled, a year's course in wool classing could be funded. A. E. Hamilton found twenty candidates and an evening class, conducted by Jeffrey, began in the third term of 1897. Among the students was Spencer Williams, later with Goldsbrough Mort, and (later Sir) Walter Duncan. First and second year classes began in 1898 and day classes began in 1899. First graduates (in 1901) were Hamilton and Norman Bickford. Later graduates include A. H. Codrington and C. A. Goddard (1903), Spen Williams (1906) and Ewen Waterman (1926). He resigned from the Lobethal factory to become an instructor and lecturer at the School of Mines and later at Roseworthy Agricultural College. Alfred S. Cheadle, G. W. Cooper, and George Dowling were examiners in woolclassing from 1900. Tom P. Reid, Dalgety's wool expert, credited the School of Mines' woolclassing course with achieving cooperation of growers in classifying their wool clips correctly.

Business In 1905 Jeffrey resigned from the School of Mines for a partnership in the woolbroking firm of Luxmoore, Dowling & Jeffrey, which shortly developed links with stock and station agents Bagot, Shakes & Lewis, Ltd. The two firms amalgamated in 1911. When George Wallwall Bagot died on 8 July 1919, his joint managing director John Lewis retired, and Jeffrey and Lance Lewis were appointed by the committee as their replacements. He had some (unspecified) part in the absorption of Bagot, Shakes & Lewis by the Sydney firm of Goldsbrough Mort & Co. in 1924. Sometime around 1920 Jeffrey left Bagot, Shakes & Lewis for the American wool buyers Lothrop, Bennett & Gillman, but while in Melbourne was struck by a motor car, resulting in a fracture of the thigh, putting him out of action for a year. Consequently he withdrew, and on recovery accepted the position of Australian superintendent for H. Dawson & Co., of Bradford, UK. He retired in 1926, but was retained by them as a consultant. During WWII Jeffrey served as a member of the Australian Wool Council, chairman of both the State Wool Committee, and the Technical Advisory Committee which negotiated prices wool growers received under the stabilisation scheme.

Character Mr Jeffrey was a man of unlimited energy, and although not at any time robust, he never let up until a few years ago. In his younger days he never walked but always ran, and there were few better known men in South Australia. [Sir Walter Duncan]

Worked examples

Example 1 — a first encounter with George Jeffrey (wool expert)

Start with the simplest possible case. Write down what George Jeffrey (wool expert) 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 George Jeffrey (wool expert) 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 George Jeffrey (wool expert) 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 George Jeffrey (wool expert)

In research
George Jeffrey (wool expert) 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 George Jeffrey (wool expert) 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
George Jeffrey (wool expert) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1853 births, 1942 deaths, Agriculture educators, so understanding it makes those chapters shorter.
In everyday life
Look for George Jeffrey (wool expert) 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.
