Introduction
Sir Geoffrey Badger was interviewed in 1997 for the Interviews with Australian scientists series. By viewing the interviews in this series, or reading the transcripts and extracts, your students can begin to appreciate Australia's contribution to the growth of scientific knowledge.
The following summary of Badger's career sets the context for the extract chosen for these teachers notes. The extract highlights Badger's work on medicinal compounds cancer-inhibiting substances and an anti-malaria sulpha drug. Use the focus questions that accompany the extract to promote discussion among your students.

Summary of career
Geoffrey Badger was born in Port Augusta, South Australia in 1916. His family moved to Geelong, Victoria when he was 4 years old and he attended North Geelong School, the Geelong College Preparatory School and Geelong College until the Intermediate Certificate.
Following school he attended the Gordon Institute of Technology at Geelong and completed a Diploma of Industrial Chemistry. He then went to Trinity College at the University of Melbourne where he studied chemistry, receiving an MSc in 1938.
Badger then went to the Chester Beatty Research Institute at the Royal Cancer Hospital, receiving his PhD in 1940 for his research into cancer-inhibiting compounds. In 1941 he started work as a research chemist with ICI in Manchester, UK. Here he was responsible for the production of the first sulphamerazine (sulphadimethyldiazine), a sulpha drug with additional anti-malarial activity that was desperately needed for the troops in Burma. He then worked in Edinburgh, UK, for the remainder of World War II, as an instructor in navigation in the Royal Navy.
In 1946 Badger took up a position at the University of Glasgow, then in 1949 he moved to the University of Adelaide as a senior lecturer and was appointed professor of organic chemistry in 1955. In 1964 Badger took up an appointment on the Executive of the CSIRO. In 1966 he returned to the University of Adelaide as deputy vice-chancellor for 6 months before being appointed vice-chancellor, a position he held for ten years.
Badger was elected to the Australian Academy of Science in 1960, and was president from 1974 to 1978. He argued persuasively for the establishment of a body to advise government on science policy arguments that led eventually to the formation of the Australian Science and Technology Council (ASTEC), of which he was the first chairman (1975 to 1982).
Badger is also a Fellow of the Australian Academy of Technological Sciences and was president of the Royal Australian Chemical Institute (RACI) and the Australian and New Zealand Association for the Advancement of Science (ANZAAS).
Badger was made an Officer of the Order of Australia in 1975, for ‘distinguished service in the fields of university administration, education and science’. In 1979 he was knighted in the Queen’s Birthday Honours list.

Extract from interview
| Researching the inhibition of cancer
Interviewer: What was the topic of your research and your thesis?
The institute had been working on cancer-producing compounds,
isolating the cancer-producing substances from coal tar. By the
time I got there, although there was a bit of that work still
to be done, people were beginning to think that if some chemicals
would produce cancer, maybe other chemicals would inhibit its
growth. So my first paper, written with J.W. Cook, was entitled
'The synthesis of growth inhibitory compounds, Part 1'. I got
up to about five or six parts in that series, on synthesising
substances which tested both for cancer-producing activity and
for inhibition of tumours. Taking mice and rats which had been
injected with a little bit of cancerous tissue and had developed
tumours, we injected compounds to see whether the tumour size
regressed. It was a very primitive method of testing but it did
show that it was going to be possible.
Is it necessary to ingest the coal tar substance in order to
develop cancer?
No. People working in coal tar used to get skin-cancers, and
cancer of the scrotum was found especially in chimney sweeps.
Unless you wash soot off, it's on your skin for a long time.
The main substance in coal tar had been isolated by the Chester
Beatty people before I arrived and a lot of work had been done
to show how cancer-producing that was and how many related substances
were also cancer-producing. The aim was to find out what causes
the substance to be cancer-producing.
When you're looking for the reverse effect you've got a huge
range of organic chemicals to choose from. How did you even begin
to find something that would inhibit cancerous growth?
People all over the world were beginning to inject jolly near
anything that could be extracted (from plants, trees and so on)
into mice with tumours, to see whether the tumours regressed.
It was a matter of trial and error, but there was sense in what
we were trying to do in London, which was to modify cancer-producing
substances to make them act in reverse.
Using science in the war effort
While you were in London war in fact did break out, in 1939.
Yes. During that time some volunteer ladies used to put on a
luncheon in the hospital, for people from the hospital and from
the institute. One of my institute colleagues and I were sitting
having our lunch one day when a lady opened the shutters and said,
'For anyone who is interested, France has fallen.' Deadly silence.
Being in one of the so-called reserved occupations, you completed
your period in London University. But then in 1941 you went to
ICI as a research chemist, didn't you?
Yes. Since I was by now a scientist (with a PhD, even) I thought
I ought to do something for the war effort and I wrote to ICI,
in the Manchester suburb of Blackley, to ask whether they could
use my services. I was appointed at 325 pounds a year, on the
strength of which I got married. My wife, Edith, and I had our
honeymoon in Huddersfield, where I went around another ICI factory
trying to learn a little bit about industrial chemistry while
she was left wondering what to do. Anyway, after three weeks
there we rented a furnished house in Manchester, where we had
three years.
I had indicated that I was interested in medicinals, and at that
time there was a need for anti-malarials. One of my first jobs
was not in the speculative research section but the process labs,
beginning to work out the process for manufacturing a hundredweight
of sulphamerazine, as it was called sulphadimethyldiazine, in
formal terms. That was not only a sulpha drug but had some anti-malarial
activity, and apparently the boys in Burma were screaming out
for it. So I made the first ton of this medicinal, and did several
other things while I was there. But I thought that I ought to
do something a bit more active.

Focus questions
- Badger used live rats and mice in his cancer research. Do you think the use of live animals is justified for medical research?
- Badger and others were working on cancer-inhibiting compounds in 1940. How much progress has been made in the last 60 years?

Activities
Select activities that are most appropriate for your lesson plan or add your own. You can also encourage students to identify key issues in the preceding extract and devise their own questions or topics for discussion.
- What are the cancer-producing chemicals in coal tar? Find out more about the incidence of cancer in chimney sweeps and others working in proximity to coal dust, and write a short essay on your findings.
- Are there substances that inhibit growth? Investigate how these can be used in chemotherapy for cancer patients.
- Find out more about sulpha drugs and why sulphamerazine also had some anti-malarial activity.
- Hold a class debate on the topic 'The 20th century will be known as the first where gunshot wounds took over from disease as the major cause of death in wars'.
-
Activities in Malaria a growing threat (Nova: Science in the news)
-
Cancer causes (Newton's Apple, USA)
A discussion on cancer-causing agents and an activity looking at human cheek cells.
-
Cancer treatments (Newton's Apple, USA)
Students simulate how cancer develops by growing moulds, and test the effect of penicillium on mould growth.
