You will know that my name is Volker Heine, and this is a bit the story of my life. I've been very lucky in many occasions. I was born in Germany, in Hamburg, in 1930, and that was before Hitler came to power. The situation in Germany was already difficult, unstable. The casualties in World War I were tremendously high. I mean, I remember reading or hearing that at the beginning of World War I, the British soldiers rode into the battle on their horses. And there were the German with machine guns. I mean, it was just slaughter. I mean, they then learned quickly, but it just shows the mind, the preparation, how World War I was like a bombshell on the world. particularly Britain, because Britain had been at peace since Napoleon, which was about 1812 or something, and World War I started in 1914. So about 100 years. So it was, and the casualties in World War I were very high, I think, for all countries, because of the machine guns were new. So Europe was unstable during those years, and there was a great expression also in the United States at the end of the 1920s. My parents met each other at high school in the 1910s during World War I, and then stayed, got married and stayed together. Then in the 1920s, I have two older siblings, an older brother and an older sister, and then a younger sister was born in 1936. Well, then, of course, Hitler came to power in 1933, and everything then changed. It was, it didn't directly affect me. I was a child, I was born in 1930, so, but it meant that I did leave and the whole family left in 1939, 1938, 1939, because it was getting dangerous to I mean, the Nazis were very strong on involving the youth. And as a teenager, it was very important to take part in those things so that my elder brother and sister went to a boarding school in Holland that it was run by Quakers from the United States and England. the United Kingdom after World War I, to try and bring at least the young people together after World War I. And then my elder brother and sister were sent there because it was getting dangerous. For secondary school, it was important to take part in these Hitler youth activities. And there's a story about my elder brother coming home and saying, oh, the teacher told us that time so and so and so were hotters and so on. Well, one of them was my grandfather on the mother's side, and another one was I met through them, and they were very nice fellows. Should I tell the teacher that she was misinformed? that would have been politically a huge mistake and would have had all sorts of repercussions. Diagonally opposite us we had the local Nazi who sort of kept an eye on our district. Every month you had to have a You didn't have to, but everybody did. It was expected. And the party thing, you have a meal cooked in one pot, and that was its name, Eintopfglich. And the money that you save, the party member would come around and collect for the party, not for the government, not for the state. This was part of life. And so this gave them an opportunity once a month to be on your doorstep and check, I mean, just chat and so on, and see how you were received and children and so on. So that was the degree of surveillance that one had. So after this story about my elder brother asking this question, should I tell the teacher? He and my older sister, who was also at secondary school, were sent off to this Quaker boarding school in Holland. It was fairly near the German border, as it happened, that part of Holland, not over in Amsterdam. And they were very happy there. It was a very nice school. In fact, My parents had been at a rather special school. German secondary education was very militaristic still in World War I and even beyond. But they, so they met at this much more liberal school. It was a private liberal school. My father's father was one of the school committee running the school. It was relatively small. And some of those teachers from that school, they lost their jobs when the Nazis came in, but then they were teaching at this school in Holland, this Quaker school. So there were these connections. So I was also sent there, but that's a slightly different story. A lot of people, of course, were emigrating. And some countries like England and the United States had already closed their doors, said, we've taken enough Jewish refugees. I mean, our family are not Jewish, but the political atmosphere was very different. As I say, one of my grandfathers was a minister in the government after World War I for a while. And yes, in fact, he was lucky that he was out of Germany with his wife on holiday in Italy. And somebody who was in the know sent him an urgent letter and said, don't come back. You're on the list to be arrested as soon as you do. Because he'd been a politician against the Nazis. And so he and His wife lived in Switzerland for the rest of their lives. And I remember visiting them there. But anyway, so my parents thought about they should leave Germany too, like a lot of other people were. I mean, we were not Jewish, but just political, the situation was untenable. 94 00:09:02,8 --> 00:09:05,345 But by that time, countries had closed their doors. But New Zealand was still interested in building up its population. It was one and a half million only. And so they got visas for going to New Zealand. But he was a lawyer by profession, but he'd had, because of this My other grandfather was in charge and built up this series of pottery factories. They were just small factories that he'd bought up that had never got back onto their feet after World War I. I mean, just think of the difference in tastes between what we would call the whole Victorian taste and after World War I, well, Picasso and all that. And so a lot of these small factories, there's a lovely, a good band of clay, runs from Sweden through an island in the north, in the sea there, and then through Germany running southwards, a bit west of Berlin, and then somewhere down to the Lake Geneva. And along this band of clay, good clay, were villages and little towns that each had their little pottery business. And it was grandfather on my mother's side that towards the end of World War I and just after World War I, these didn't make it back onto their feet commercially. And he bought them up very cheaply and he built up a little empire that way. And my father was often the troubleshooter for him when, I mean, these were just little factories all over the place. And so father had been interested in science. His brother went into science and he went into law, but he could, it was up and touch and go whether he would follow science or law. as it happened, it was law that he decided on, but he was still interested in science. And so the idea was to go to New Zealand, but would there be a job for him? I mean, he was a lawyer, and a lawyer is not a job, you can move from one country to another because the laws are different, and you have to, and of course, the clique of lawyers I mean, they're very tightly controlled and you'd have to start again at the beginning of studying law in that country. Well, who would pay for that? So the question was whether he could go to New Zealand and find through this general business experience and something to do with the pottery industry whether there would be a job for him. So they set off in 1939. And this meant that I went to this boarding school in Holland also. Of course, I was aged 8 and a half, and this was a secondary school. But there were other families who were in a somewhat similar situation, particularly Jewish emigrants. And so the school had a baby class as well. I'm not sure at what age it actually started, but then it had a baby class that I know, and I was the youngest in the baby class. But I could do arithmetic. I was always good at that. And so I was able to be with them and move up into the mainstream of the school in September in 1939. So we all had visas for New Zealand. And then there was also my younger sister, who was age 3. And she was also in Holland with the governess to look after her. So that we were all out of Germany. I mean, they didn't expect a war to start, obviously. But you never knew. And then it happened that father, as I was saying, was sort of, he was the legal and financial director of the ceramics company of my grandfather, my mother's father's side, who had died in early 1930. 153 00:13:54,234 --> 00:13:58,4 And then another uncle died in that family. Well, when an uncle died, he was one of the directors of this ceramic company. And then there had to be some changes, of course. And in particular, one of the brothers was rather than Shark. And the widow of the uncle who died needed to be protected and so on. So father traveled back to Germany in the summer of 1939. It was possible to fly at that time already, not very easily. You went on a plane in the morning and then flew and landed on a harbor. So these were seaplanes. And then you stayed in a hotel and the next morning you took off for the next one. So that was how he got back to Germany. And he was just going to be there for two weeks to tidy up the legal aspects of the company and the change of the directors and so on. During those two weeks, the war started. And so he was stuck there until 1947. I guess it was 1947 when he then finally got to New Zealand. He couldn't come, the Allied Allies didn't let people out immediately that the war was finished, because then all the Nazis would have disappeared. Some of them, of course, had already got out through Spain, and Spain was a friend of the Nazis. That was how it evaded being overrun militarily. But What was I going to say? Yes, so father was just back for two weeks and got stuck in Germany then. Well, then there were us four children in Holland, including younger sister, age 3. But we had visas to go to New Zealand, and then at the end of October we left. to England and then to New Zealand, my ship, of course. Interestingly, the ship kept zigzagging. This was to try and avoid torpedoes because the submarine has to expect where will the ship be exactly so many minutes from now and then line itself on that spot and so on. And that's why the ships sort of zigzagged along, etc. This was part of crossing the ocean in wartime. Anyway, we got to Australia and then from Australia to New Zealand. But my mother was there in a hotel room just had to get a cleaning job. She, of course, wanted my younger sister, who's three years old, nearly four, I suppose, to stay with her because, I mean, the other three older ones, me and my older brother and sister, we got sort of, not adopted, but cared for by three different families. But a three-year, four-year-old, it would have to be an adoption, and that would be the end as far as my mother was concerned, and she just didn't want that. And so she only sought jobs where she could have young Viola with her living in. Those jobs were not easy, especially during the war then, and being an enemy alien and and so on. I mean, having employing her, having her living in with the child had sort of, well, it made people ask questions politically and so on. So, but then she was lucky and a farmer, his wife left him and they had children, three children of similar age to my sister Viola. And so she had a job there as housekeeper for this farmer and their family. And I was very welcome there during my school holidays. I was cared for by a family in a different city, Wanganui, and they had four children of their own, and they just added me to their four children. And I had a very good time there. I could I could discuss a bit the life that I had there. I mean, the heating of the water in the house was purely by wood. Well, the climate was okay, warm-ish. I mean, it was a bit cold in winter, but the hot water daily. And so it needed a lot of chopping of wood for the hot water system. And that was my job. And we had one cow. 218 00:19:26,566 --> 00:19:33,6 And so then at the end of the milking, dad, that was Mr. 219 00:19:33,6 --> 00:19:38,645 Veitch or Jock, who was the eldest son, they did the milking of the cow. But I did the separating of the milk from the cream, which is a centrifugal force thing, and then the cleaning it up afterwards, as well as chopping all the wood for the heating and some of the cooking. So I was busy and I was physically very active. And Zizi remarks how strong I am still in my shoulders and my arms. And that still remains from that as a teenager. So that was my life and I was very happy with them. I went to a good school. Dad, as I called him, as the other children did, was a teacher at a secondary boarding school teaching bookkeeping and economics, which was important for, I mean, it was a school, it was 80% boarding school, modeled on Eton and these posh schools in England. But in New Zealand, it wasn't exactly posh. It pretended to be and tried to be, but it wasn't in reality. But there were mostly children from doctors and professional people with borders. 80% of them were borders. And then there were some from Wanganui itself, like me. And Yes, I was very happy there and did well, yes. And at the end of my secondary school there, I won a scholarship, there were public exams. I won a scholarship to go to the university, which didn't pay everything, but it was one of the better quality ones. And so But then as well as that, I worked during the school holiday, during university holidays and the summers, and earned extra money that way. So I was financially independent of the each family who looked after me all during the war, just as there was one of their sons, they had Jews, and they also came also at the school, same school. Yes, and then I was, yes, I was independent then. I had to be, as I said, washing dishes at the student hospital the first year that I was there and things like that. Then during the long vacations in the summer, working on a farm or on some other job. One was on a building job. And that's how I then grew up and then I I won other scholarship staff to carry me forward. So I did a master's degree in maths in one year because, this was because of the New Zealand situation. It wasn't, I mean, here people come up to do a maths degree and they already know a lot of maths. In New Zealand you couldn't, didn't have that. And so I could do that in one year. I'm not the only person. And then I did two years for physics, master's degree, including an experimental thesis. So I won enough scholarships to carry me through those. And then at the end of that time, I won a scholarship to come to England. That was a That was a bit better paid than any of the others. I mean, people were not conscious of inflation, at least not inflation proofing things the way they are now. But this was a scholarship from the Shell Company, the International Shell Company. And they, of course, understood about inflation. And so it was a better, higher level. The New Zealand is sort of divided into four sections, two in North and two in the South Island. And these, the heads of the Shell in those four years, they'd come together every now and, and including for selecting the person for the Shell Scholarship. 279 00:24:23,863 --> 00:24:28,1 I think it was one of their sort of goodies to come together, a nice thing to do, meet these young people and have a lunch together and so on. And The personal manager in Wellington, the top one, didn't expect me to be a serious candidate. But I don't know why, but he was interested in the testimonial that my maths professor had written. And I don't know, my maths professor was quite a a character, but in a very good way, in a very sensible way. He'd been a, he'd come from England at the end of the war, he'd been a city councillor in Leeds, you know, that was in the bomb flight path to Liverpool. And as a city councillor, he was very much involved in, I mean, he wasn't called up, he was stayed in, it was one of the northern cities, I can't remember which one, being a very responsible person. So he was very good. But anyway, the personnel manager of Shell in Wellington thought, I wonder how the person, when we meet him, squares up with what the professor wrote about him. And so instead of being off the list, *** **** it, the others, they all voted for me for the scholarship. So I was lucky. And that then pulled me the next year to Cambridge. And here was another lucky thing. Neville Mott was professor in Bristol and out in New Zealand. I didn't. I knew somebody had come back from England and said, Mott is the right person for you to work with because of your interests. And so I was applying to Bristol. But then they, in London, the Shell people, picked up on their antenna that Mott would be moving to Cambridge. And so they switched my application to Cambridge and probably had to pull one of, you know the English expression, pull strings, yes, so as to get me also into a college. And so, in fact, I arrived in Cambridge, and that was in 1948, October, the same time as Mott arrived from Bristol. And this is now the story that you like. 316 00:27:16,2 --> 00:27:22,175 What I hadn't realized was that Mott didn't have a circle of graduate students around him. He wasn't a person to build a group in that way. But he was very good at talking with experimentalists, and he'd done this during the war. And seeing things that needed doing where theoretical physics or somebody like with our back kind of background could be helpful. And so He said, well, I'm going to be rather busy and with this new job, but wouldn't you like to do with ionosphere or fluid dynamics or something? And I spent a day and I thought, no, I don't. I mean, what attracted me was, well, metals, solids were down to earth. And as a New Zealander, you know, that was practical, not ionosphere. Who cares about the ionosphere in New Zealand? a population of one and a half million, and a country that stretched over a thousand miles. And you only had one and a half million people. You had to be down to earth, as we use the expression. And so the quantum, but this was the first time, really, after World War II, that quantum mechanical calculations could be done. Well, in the 1930s, there had been calculations on individual atoms, hydrogen, helium, lithium, and so on. They'd got as far as aluminium by the time I came in 1947, '48, '47, '48? What was it, '47 or '48? I said, I came in '48, I think. Well, I got lost. But anyway, yes, because this was a real quantum mechanical calculation. One of the early ones that directly related to the experimental work that was going on at that time. And so this, it was on the one hand, the future, quantum mechanical. On the other hand, it was down to earth. It was doing some calculations relating to measurements that they were doing at that time in Cambridge. So this was ideal for my conception. So I was very lucky. And so Mott said, well, why don't you go down to the low temperature group and see if you can make yourself useful. And Lucky me, I found something that I did could do. The first project that I looked at were heavy metals, and the quantum mechanics of heavy metals I couldn't do at that time. But light metals like aluminium with orthogonalized plane waves were possible. And Mott was extremely helpful in keeping me in touch with that was going on in the United States. There was practically none except some magnetism in this country, and there was nothing on the continent. This was just after the war, it took time to recover and start building up. So I worked in some ways as an offshoot from the United States, because what received from every quarter John Slater, as part of his contact with the research contract, wrote up in a volume each quarter, I think, or each half year, what was going on in the field of electronic structure of solids for everybody, and what was one of the people who received this. So from that, I knew what was going on about orthogonalized plane waves And so on. So I was lucky in that. All these lucky things together. Yeah, in two years, instead of three years for a PhD, I'd finished in two years. And off I went to the United States. Mott arranged for me to work with Charlie Cattell in Berkeley. Charlie Cattell himself was not in good health, and he was in Hawaii for his health. But so I was there instead of him relating to some of the experimentalists in Berkeley and then also in elsewhere around the United States. I went traveling along, I was encouraged to do that. So that got me into the swim of the state theory. And then, yes, then after one year, I had a position in Cambridge that I could go to a university, not a teaching position, but a research position, but that I could do what I liked. And so I went back to the Cavendish and started doing electronic structure things, continued doing electronic structure things, and gradually building up the group. At what time were you become a member in Clare College? When you arrived, maybe you were in... No, I wasn't from New Zealand. I was rather suspicious of colleges, and I didn't try to become a member of a college or anything. But then in 1960, the person who had, Brian Pippard, who had been doing the physics teaching in and Clare became a professor or something and was not, if you're above a certain level, you can't do, you cannot get paid for college teaching. You're allowed to do it, but you have to do it free. So in practice it doesn't happen. And so in 1960, Eric Ashby was just appointed as the new head of Clare. And everything changed. The previous master of Clare had been senior tutor and master for 50 years. So if you count back 50 years from the 1940s, that takes you before World War I. And so you can imagine. I mean, he did a wonderful job through the Depression and through the war and so on. But there was a feeling amongst the existing fellows that it needed to move into the 20th century. And so I felt at home there straight away. And so I was appointed three years in the first instance, but then it rapidly became clear that I was happy there. I mean, although my image of colleges from New Zealand was much more old-fashioned, and I was not like that. So yes, and of course, the 1960s were a time of upheaval. I mean, it was The government expected Cambridge, well, after World War II, everybody realized that you needed an educated workforce. And so the number of positions for universities, the new universities at Brighton and Bath and so on were all founded in the 1950s or 1960s, and they were attracting a whole whole new range of students. And so there was a lot going on in these directions, including changes in Cambridge. And the number of fellows had to increase, and the government demanded that the number of students was increased, and so on. So there was a general atmosphere of change. And of course, then people, some people suggested, well, why keep single sex colleges? Why not go co-ed? And King's College and Churchill College decided in the 1960s that they would go in. And then it took a bit of time for the schools to be informed and so on, that people would apply. I mean, at that time, people made applications for going to Cambridge colleges for some years before because their father had been there, et cetera. was a very old-fashioned kind of family tradition. So a lot of adjustments, detailed adjustments had to be, psychological adjustments had to be made. And this came during the 1960s. And one of the questions was, well, why not go co-ed? And have women in the colleges. Instead of, you see, there was Girton College, way miles out of town, and then there was Newnham. And that was all. And Well, this discussion was going on in several colleges, not in others, but it wasn't clear. And then I remember the time came where it was clear that we should either go with the other two colleges, which was Churchill and King's, or not at all, I mean, or put it off for some years. And this was then 1970 that they were going. So in '68, Claire really had to get off the fence, as we say in English. And then we voted and we agreed to go to that we would go ed, but only by one vote. It required to change the statutes of the college, required a two-thirds majority of the fellows. And two-thirds is quite a lot. And so we were right on that borderline. And so But then we had to have a special meeting, specifically according to the statute, designed for changing of the statutes of the college. Well, then I was away and somebody else was away, and the two-thirds majority was away. But the feelings were very intense in a way that even surprised me. I remember writing that it's the only time in my life that I have seen grown-up men literally hysterical at this idea of going, go ahead. I don't know whether when we finally did, they still felt that way, I hope not. I don't think so. I think, I mean, it all went so smoothly. And Yes, then in 1970, we had the Girls Cup, yes. We had a two-thirds majority, and that worked and through. But only just by, you know, by one version. I didn't know that part of the story. 476 00:40:01,868 --> 00:40:05,5 When I was first arrived in Clare, Those fellows and also information leaflets describe the proud things in the history of Clare College. Become one of the three colleges, first accepting female students was one of the proud things. Which year did you come? Ninety-one. Ninety-one. So it's quite a long time later. Yes, Because this was 1970. Yes, Well, it was interesting.
