Another tōtara falls
It’s been a tough year for those of us who admire the real shapers of our society. First it was Christopher Doig, who did so much for those very different passions: cricket and opera. Then there was Lloyd Morrison, who combined an entrepreneurial drive with a fierce belief in New Zealand and its culture. Then Jock Hobbs, who saved professional rugby and brought us the world cup (and was not a bad loose forward in his time). And now we mourn the loss of the country’s greatest scientist, Sir Paul Callaghan. They were all men who were cut off when they still had so much to give.
The tributes have already flowed widely for Paul Callaghan; but we have a special reason to remember his achievements, because nine months ago we launched a short biography he wrote for the Dictionary of New Zealand Biography on another very great scientist and Nobel Prize-winner, Alan MacDiarmid. At the time I wrote a blog post pointing out that Sir Paul and his subject shared a great deal in their careers. Both were outstanding scientists in their respective fields. Paul Callaghan’s real speciality was how molecules moved in complex fluids, and he used nuclear magnetic resonance to explore these matters. But his research never remained just detailed papers hidden away in specialised journals. He always had a larger vision, and so other institutions flowed from his genius.
First, he set up an institute at Victoria University of Wellington to study advanced materials and nanotechnology. He called it the MacDiarmid Institute and it was the first, and rapidly became the most successful, of the country’s centres of research excellence. The centre attracted collaborators from around the world, pulled there by Paul Callaghan’s huge reputation and his wonderful skills of collegiality.
Second, Sir Paul was clever enough to see that his work in these areas also had real commercial value. So he put together a group to develop practical and commercially viable applications for his researches into nuclear magnetic resonance. Magritek was founded in 2004 with two employees. Today it employs over 20 people and sells its technology to companies throughout the world.
Paul Callaghan was a great scientist and an energetic entrepreneur and founder of institutions, but he was also a very great communicator. Anyone who heard one of his lectures will never forget his sheer enthusiasm, the clarity of his thought and the intellectual engagement he inspired in his audiences. For many New Zealanders this was discovered through his wide-ranging conversations on the radio with Kim Hill, which later became a book. Increasingly, in his last years he realised the importance of this public role. He presented to us a vision of a New Zealand which was no longer a country of sharemilkers and freezing workers, but of smart highly educated people who brought affluence to this country through their creativity and their scientific smartness. Few people better exemplified this Kiwi of the future than Sir Paul himself.
Finally, let me say personally that from those wild days in Weir House (a university hostel) in the 1960s, when I first met him as a fellow student, to a brief conversation several months ago, Paul was always a warm and extraordinarily generous human being. I have never heard a harsh word against him.
Te Ara is enriched by having Paul Callaghan’s authorship in our ranks. His fine biography of Alan MacDiarmid reflected his own aspirations as a public scientist. I hope that as you mourn his departure take a few minutes to read this superb short biography. It says as much about the author as the subject.
