gentry. Eighteenth century In the eighteenth century the universities went from being small and parochial institutions, largely for the training of clergy and lawyers, to major intellectual centres at the forefront of Scottish identity and life, seen as fundamental to democratic principles and the opportunity for social advancement for the talented. Chairs of medicine were founded at all the university towns. By the 1740s Edinburgh medical school was the major centre of medicine in Europe and was a leading centre in the Atlantic world. Access to Scottish universities was probably more open than in contemporary England, Germany or France. Attendance was less expensive and the student body more representative of society as a whole. The system was flexible and the curriculum became a modern philosophical and scientific one, in keeping with contemporary needs for improvement and progress. Scotland reaped the intellectual benefits of this system in its contribution to the European Enlightenment. Many of the key figures of the Scottish Enlightenment were university professors, who developed their ideas in university lectures. Key figures included Francis Hutcheson, Hugh Blair, David Hume, Adam Smith, James Burnett, Adam Ferguson, John Millar and William Robertson, William Cullen, James Anderson, Joseph Black and James Hutton. Modern era At the beginning of the nineteenth century, Scotland's five university colleges had no entrance exam, students typically entered at ages of 15 or 16, attended for as little as two years, chose which lectures to attend and left without qualifications. The curriculum was dominated by divinity and the law and there was a concerted attempt to modernise the curriculum, particularly by introducing degrees in the physical sciences and the need to reform the system to meet the needs of the emerging middle classes and the professions. The result of these reforms was a revitalisation of the Scottish university system, which expanded to 6,254 students by the end of the century and produced leading figures in both the arts and sciences. In the first half of the twentieth century Scottish universities fell behind those in England and Europe in terms of participation and investment. After the Robbins Report of 1963 there was a rapid expansion in higher education in Scotland. By the end of the decade the number of Scottish Universities had doubled. New universities included the University of Dundee, Strathclyde, Heriot-Watt, and Stirling. From the 1970s the government preferred to expand higher education in the non-university sector and
