Reference excerpt

The Sir William Dunn Institute of Biochemistry at Cambridge University was a research institute endowed from the estate of Sir William Dunn, which was the origin of the Cambridge Department of Biochemistry. Created for Frederick Gowland Hopkins on the recommendation of Walter Morley Fletcher, it opened in 1924 and spurred the growth of Hopkins's school of biochemistry. Hopkins's school dominated the discipline of biochemistry from the 1920s through the interwar years and was the source of many leaders of the next generation of biochemists, and the Dunn bequest inaugurated a period of rapid expansion for biochemistry.

Origin of the Institute In 1918, a trustee of the estate of Sir William Dunn approached a Cambridge biologist, William Bate Hardy, about the possibility of putting some of Dunn's estate toward biomedical science research. Hardy referred the trustee (Charles D. Seligman) to Walter Morley Fletcher, the secretary of the Medical Research Council. The Dunn estate, like much of the philanthropy world, was beginning to look more to "preventive" philanthropy (as opposed to direct aid to the needy) by sponsoring research institutions that could address social ills. Between 1919 and 1925, Fletcher convinced the Dunn trustees to put nearly half a million pounds toward biomedical research. Fletcher was a long-time friend and institutional ally of Frederick Gowland Hopkins, a pioneering biochemist who was trying to establish "general biochemistry" as a field distinct from either medical physiology or organic chemistry, more a part of biology than medicine. Fletcher lobbied for the Dunn estate to fund Hopkins's proposal, among the over 500 funding proposals submitted. By late 1919, Fletcher was negotiating for a considerable endowment that would allow Hopkins to create an institute solely devoted to biochemistry. The approval of this endowment, ultimately about 210,000 pounds, reversed the declining fortunes of Hopkins's research group, which had been suffering from lack of available academic positions, research space, and able students since World War I. With funding in the works, Hopkins group expanded from 10 researchers in 1920 to 59 in 1925; in 1922 they began using endowment funds and in 1924 the Dunn Institute of Biochemistry opened. Hopkins became the first Sir William Dunn Professor of Biochemistry and head of the new University of Cambridge Department of Biochemistry, and he appointed researchers in a range of specialized fields covering the whole of what he considered the proper, broad domain of biochemistry.

Hopkins's school of biochemistry Hopkins's school, housed in the Dunn Institute, was both productive and influential. Between World War I and World War II, 40% of the papers in the Biochemical Journal were authored by Hopkins and other Cambridge biochemists. Hopkins's program of "general biochemistry" was unique in having a stable institutional base (unlike in Germany, where there were only a scattered handful of biochemistry professorships) but not being dependent on a medical school (unlike the biochemistry and physiological chemistry departments in the United States). The Dunn Institute under Hopkins had another unusual feature for the time: Hopkins did not discriminate against hiring Jewish scientists, unlike the large majority of American, British and German universities and medical schools. This may have helped Hopkins assemble such a strong group of researchers, since talented Jewish biochemists had few other options.

Worked examples

Example 1 — a first encounter with Sir William Dunn Institute of Biochemistry

Start with the simplest possible case. Write down what Sir William Dunn Institute of Biochemistry 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 Sir William Dunn Institute of Biochemistry 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 Sir William Dunn Institute of Biochemistry 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 Sir William Dunn Institute of Biochemistry

In research: Sir William Dunn Institute of Biochemistry 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 Sir William Dunn Institute of Biochemistry 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: Sir William Dunn Institute of Biochemistry is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1924 establishments in England, Biochemistry research institutes, Biological research institutes in the United Kingdom, so understanding it makes those chapters shorter.
In everyday life: Look for Sir William Dunn Institute of Biochemistry 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.
