KU Leuven: Faculty of Science



The history of the Faculty of Science runs parallel with that of the University of Leuven, with four major periods:

  1. The Old University (1425-1797)
  2. The University (1817-1835)
  3. The Catholic University (1835-1968)
  4. The autonomous Dutch-speaking Catholic University (from 1968)


In 1425, Pope gave Martinus V permission to establish a Leuven general with four faculties: Artes, Canon Law, Civil Law, and Medicine. In 1432, a Faculty of Theology was added, making the studium generale to medieval concepts a full-fledged university. From the outset, science education was an important component of Leuven University: both natural sciences were studied in the Artes as well as in the medical faculty.

The Artes faculty was the forerunner of the current Faculty of Arts and Sciences. Students were initially trained in the seven 'liberal arts', subdivided into trivium (grammatical-literary education) and quadrivium (mathematics, music, and astronomy). This education was soon transformed into a threefold education in logic, physics, and metaphysics. The master diploma in the Artes gave access to the higher faculties (Theology, Law, and Medicine).

In the early days of the Old University, a number of important scientists stayed in Leuven. Gemma Frisius (pictured) was a mathematician, cosmographer, and medic with international fame. Frisius introduced topographic triangulation and thus laid a solid mathematical basis in cartography. Gerard Mercator, the father of modern geography, was a pupil of Frisius. Rembert Dodoens and Carolus Clusius, founders of empirical botany, also studied in Leuven. Yet another pioneer of modern medicine, Andreas Vesalius, received his basic scientific training in Leuven.

After the heyday of the 16th century, natural science education fell into a crisis. Although the faculty quickly incorporated the scientific innovations into its program, it remained long-frowning with respect to Newtonian physics. It was not until the 18th century that the now obsolete structures of the faculty were adapted to the scientific standards of the Enlightenment. By 1780, education in Leuven was up to standard again and even original research was carried out. Jan Pieter Minckelers discovered a combustible gas, extracted from coal, which he used to light his auditorium. But the political situation made a sustainable new bloom impossible. After the annexation of the Southern Netherlands to France, the Old University was abolished on October 25, 1797.


During the 19 the century, the Faculty of Science gradually acquires a new place in university education. Natural sciences are no longer just a preparation for medical studies. In 1869 six degrees of doctorates were available: mathematics, physics, chemistry, geology-mineralogy, botany, and zoology. In 1900 there is geography and in 1919 the pure and applied chemical sciences.

The Special Schools for Engineers, founded in 1864 within the Faculty on the initiative of a number of Catholic industrialists, were granted the status of autonomous faculty in 1961. The Institute for Agronomy, founded as an independent institute in 1878, was also associated with the Faculty of Sciences from 1892 onwards.

Original research is from the 19th to the explicit task of the university century. The paleontologist and zoologist Pierre-Joseph Van Beneden was a passionate scientist, who published studies on marine biology and parasitic worms. Van Beneden also contributed considerably to the development of the Museum of Zoology. The chemist Louis Henry opened his laboratory for chemistry in 1863, and under his impulse practical and personal research became part of the course. Henry himself did research in organic chemistry. Jean-Baptiste Carnoy set up a laboratory for cytology and also started a practical microscopy course. His successor Frans Alfons Janssens is the discoverer of the crossing-over during meiosis. The geologist Charles-Louis de la Vallée-Poussin studied, among other things, the geomorphology of the Meuse valley, his son Charles-Jean de La Vallée Poussin did original research in mathematics, particularly in the field of integral and differential calculus and prime numbers. His Cours d'Analysis Infinitésimale (originally published in 1903 and 1906) is still being used; the last reprint took place in 2003. De la Vallée-Poussin was also the promoter of one of the most important natural scientists at Leuven University: the cosmologist Georges Lemaître, founder of the big bang theory.


From 1968 the French-speaking department of the Leuven University was transferred to Louvain-la-Neuve. The Faculty of Science gradually moved to the new campus in Heverlee, where all departments are now housed, with the exception of a part of the Department of Biology. Since the 1980s, the range of programs has been expanded with a computer science program, first a scientific and a law degree since 1992.

Currently, approximately 2,400 students are studying at one of the eight Bachelor's programs and the twelve Dutch-speaking and nine English-taught Master's programs at the Faculty of Science. In addition, the faculty also participates in ten master's programs that are organized in collaboration with other faculties.

Master of Digital Humanities (Leuven)

campus Período integral Meio Período September 2018 Bélgica Leuven +1 mais

The Master of Science in Digital Humanities helps graduates from Humanities, Social and Behavioral Sciences programs to develop digital competencies that will allow them to add digital dimensions to their own domain expertise. It aims to explicitly link these competencies to research questions, case studies, and applications related to the domain expertise of the students. [+]

Digital Humanities is a young field of research, focused on the use of computational techniques to support research in the Humanities, Social and Behavioral Sciences. One of the key drivers of the field is the recent availability of large digital repositories within many areas of the Humanities, Social and Behavioral Sciences. These repositories offer the prospect of applying computational visualization, querying and analysis techniques, leading to the discovery of new knowledge and insights. The field also applies new digital techniques to enhance approaches, processes, skills, and methods developed and applied in the Humanities, Social and Behavioral Sciences. This includes the use of digital techniques in instructional sciences, the use of digital games in social sciences or the use of digital techniques in online publishing.... [-]

Master of Space Studies (Leuven et al)

campus Período integral Meio Período September 2018 Bélgica Leuven +1 mais

The Master of Space Studies program is designed to prepare scientists to respond to a myriad of challenges and opportunities. In addition to coursework in space sciences, the curriculum is enriched by a Master's thesis and a series of guest lecturers from international, national and regional institutions. [+]

The space sector plays an important role in economic, social, technological and scientific developments. The future of the sector and its manifold applications require highly skilled experts with a broad interdisciplinary perspective. The development of innovative space technologies is fostered by an intense symbiosis between technological sectors and the challenges set by fundamental research in exact and biomedical sciences. Additionally, the economic and social valorization of space technologies requires an efficient relationship between project developers and the economic sector.

The large scale of space projects imposes important constraints on management. The international character of the space sector and of its broad applications, including the relevance of space for security and defense, implies a need for European and international legal and political measures.... [-]
