In the second part of a mini-series, Norman Biggs, Emeritus Professor in the Department of Mathematics, gives a brief history of mathematics at LSE. He covers the structure of the department, the move away from the traditional BSc (Econ), and development of Mathematics as a degree in its own right.
At the start of the academic year 1988/89 the Sub-Department of Mathematics had 6½ members. In addition to the newly-appointed professor, Norman Biggs, there were three long-standing members: Elizabeth Boardman (appointed in 1971), Adam Ostaszewski (1976) and Steve Alpern (1979). Haya Freedman had retired in the summer of 1988, and the vacancy had been filled by a temporary lecturer, Nick Gilbert. John Bell was still in post, but he had been offered a chair at the University of Western Ontario, and was planning to leave in 1989. The half-post was a position shared with the Operational Research sub-department, held by David Connolly. There was a commitment to replace Freedman and Bell permanently, and this duly resulted in the appointment of Graham Brightwell (1989) and Martin Anthony (1990).
The incoming professor knew little about the LSE, and thought he ought to find out more. A circular letter to other departments about their mathematical needs and activities brought forth a mixed response, but it led to several useful insights. For example, it transpired that some members of the Economics Department were highly mathematical, although they tended to regard us simply as a resource for teaching those parts of mathematics that were deemed useful in economics. It was clear that the goodwill of this powerful department ought to be nurtured. The Department of Accounting and Finance reported that their current hot topic was “Black-Scholes Theory”, at that time largely unknown in mathematical circles.
In order to provide a focus for research activity, an obvious first step was to set up a regular weekly research seminar. The title “Discrete and Applicable Mathematics” seemed appropriate, and it was easy to find speakers. The question of listeners was more problematic, but the members of the sub-department were willing, and there were several others working in and around London who attended regularly. The LSE had intellectual objections to the provision of a free lunch but, after some negotiation, free coffee was provided and generally the attendance was good.
On the teaching side, the arrival of a new professor prompted a review of the courses offered to undergraduates. The sub-department was involved with two ‘specialist’ programmes: the degree in Mathematics which been set up back in the 1960s, and the option in Mathematics and Economics which was part of the old BSc (Econ). It was strange that we played no part in selecting or advising students taking the Mathematics and Economics option, and possibly that was the reason why the numbers graduating in this subject were surprisingly small – only 12 in 1990.
The numbers for the Mathematics degree were also quite small, and a large part of the staff-student ratio was attributable to several courses in “Mathematical Methods”, which were attended by students taking degrees in economics and accountancy. It was necessary to move forward carefully, in order to expand the curriculum in mathematics without damaging the service teaching which justified the resources allocated to us.
Dr Michele Harvey had been a part-time teacher at the LSE since 1979, and in 1989 she was joined by Dr Joan Davies. Together they developed the main Mathematical Methods course into a coherent and highly successful operation, which did much to enhance our reputation as an essential part of the LSE. In due course we were allowed to reward Drs Harvey and Davies with proper contracts, and the title of Instructor. Consequently we were able to re-structure gradually the courses in specialist mathematics. At the start of the 1990/91 session a booklet was produced, with the grandiose title “Mathematics at LSE: education for the next century”. We managed to present a well-established programme of teaching, even if the foundations were not quite as firm as they appeared.
On the research front, steps were being taken to find a niche for mathematics in the LSE context. The weekly seminar in Discrete and Applicable Mathematics was well-established, and research activity was encouraged by the publication of a series of Research Reports. These included work by visitors and members of other LSE departments, as well as the core mathematics group. These visible signs of activity helped to raise the profile of mathematics in the School.
At the start of the 1995/96 session we welcomed the first intake to the new degree in Mathematics and Economics, which had replaced the old option in the BSc (Econ). We now had sole responsibility for this degree, which allowed us to introduce a slightly broader mathematical curriculum, although many areas of mathematics were still not covered. Jointly with the Statistics Department we were also involved with a new degree in Business Mathematics and Statistics. The teaching programme was going well, and some members of the department even found time to publish textbooks, such as the one below.
The degree in Mathematics and Economics attracted an increasing number of highly-qualified applicants, and this provided a good basis for our attempts to appoint additional staff. The first step took place in 1997, when Bruce Shepherd left to take up a position at Bell Laboratories in the USA. We were able to replace him with a full post in Mathematics, and again the field of applicants was impressive. Bernhard von Stengel was appointed, joining in September 1998.
As the 1998/99 session approached, the department was in a healthy state, but by no means flourishing. New accommodation in Columbia House had been provided, and the teaching and research activity was beginning to resemble that provided by Mathematics Departments in other universities. But there were challenges ahead, because the government had decided to continue its efforts to assess the ‘quality’ of research in universities – and to apply the same methodology to teaching. Another uncertainty was that the LSE had appointed a new director, a sociologist with little knowledge of mathematics, so the future would be interesting.
