Reference excerpt

Mary Campbell "Mollie" Dawbarn (5 January 1902 – 24 May 1982) was an Australian biochemist and nutritional physiologist. She is particularly well known for her research on B complex vitamins. Producing an assay for vitamin b12 and perfecting the methods for estimating B1 vitamin in bread are among her most notable works.

Early life and education The daughter of Gilbert Joseph Dawbarn and Mary Isabella Macdonald, she was born in Ballarat and moved to South Australia in 1907. Dawbarn won a scholarship to the Methodist Ladies College in Adelaide. She earned a BSc and a MSc from the University of Adelaide in 1923 and 1928 respectively. She achieved her DSc from the same university in 1958.

Career She began work in 1924 as a biochemistry demonstrator at the university. In 1927, she became a research chemist for the Animal Products Research Foundation, University of Adelaide. While on study leave from 1933 to 1934, she worked at the Lister Institute of Preventive Medicine in London and the University of Strasbourg in France. During World War II, she conducted research for the Australian armed forces into nutritional requirements. In 1954, she was named principal research officer for the Division of Biochemistry and General Nutrition, at the Commonwealth Scientific and Industrial Research Organisation. She retired in 1963.

Later life During her retirement, she traveled for several years and later served as treasurer for the South Australian Ornithological Association. She was very interested in photography and was an expert photographer herself. She produced black-and-white enlargements by herself. She was also member of Adelaide Lyceum and Soroptimist club. Dawbarn died in Adelaide at the age of 80. After her death, her body was cremated.

Worked examples

Example 1 — a first encounter with Mary Campbell Dawbarn

Start with the simplest possible case. Write down what Mary Campbell Dawbarn 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 Mary Campbell Dawbarn 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 Mary Campbell Dawbarn 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 Mary Campbell Dawbarn

In research: Mary Campbell Dawbarn 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 Mary Campbell Dawbarn 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: Mary Campbell Dawbarn is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1902 births, 1982 deaths, 20th-century Australian women scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Mary Campbell Dawbarn 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.
