Willem Jacob ‘s Gravesande was born on 27 September 1688, the son of Dirk Storm van ‘s Gravesande, sheriff and councilor of the city of ‘s Hertogenbosch and steward of the lands of William III, King of England, and later of Prince William IV. On his mother’s side, ‘s Gravesande was descended from the Leiden professor Johannes Heurnius. Educated at home, ‘s Gravesande entered the university of Leiden in 1704, at the age of sixteen, in order to study Law. In his studies he concentrated, however, on the mathematical sciences, for which he had shown an aptitude at an early age. He obtained his doctorate in Jurisprudence in 1707, with a dissertation on suicide, and for a decade practiced Law in The Hague. Here, in 1713, he was the co-founder of Journal litéraire de la Haye, an important journal to which he contributed book reviews and papers for two decades. In 1715, ‘s Gravesande was secretary of a delegation sent by the States- General to congratulate King George I on his accession to the English throne, ‘s Gravesande spent a year in London, where he attended sessions of the Royal Society, was elected to membership in that body, and made the acquaintance of Newton, Desaguliers, and John Keill. His visit was an important shaping influence on the style of ‘s Gravesande’s science.

In 1717, ‘s Gravesande was appointed professor of astronomy and mathematics at Leiden. His inaugural lecture was entitled De Matheseos in omnibus scientiis, praecipue in physicis, nec non de astronomiae perfectione ex physica haurienda (On Mathematics in all the Sciences, especially in physics, and also about the Perfection of Astronomy to be Derived from Physics). He remained at Leiden until his death, adding the professorship of civil and military architecture in 1730, and finally becoming professor of philosophy in 1734. In 1720, he married Anna Savelaire, with whom he had two sons.

Under ‘s Gravesande and Herman Boerhaave, the University of Leiden became the foremost scientific university in Europe, and each year a large number of foreign students came to study science and medicine there. Heavily influenced by English science during his visit to England, ‘s Gravesande introduced Newtonian science, both the tradition of mathematical physics of the Principia and the experimental science of the Opticks. It was through ‘s Gravesande that Newtonian science formed a beach head on the Continent. Voltaire came to Leiden in 1736 to consult Boerhaave on his health and follow the lectures of ‘le profond ‘s Gravesande’ on Newtonian science. ‘s Gravesande was, however, no slavish follower of Newton. In his well-known ‘Essai d’une nouvelle théorie du choc des corps fondée sur l’expérience’, published in Journal literaire de la Haye in 1722, he used the concept of vis viva of Huygens and Leibniz instead of Newton’s momentum.

In his lectures, ‘s Gravesande followed Keill and Desaguliers, incorporating experiments that demonstrated the scientific principles in question. Most of the instruments for these demonstrations were constructed by Jan van Musschenbroek, brother of the Leiden professor of physics, Petrus van Musschenbroek. ‘s Gravesande’s most important publications were treatises and textbooks. His Physices elementa mathematica, experimentis confirmata. Sive, introductio ad philosophiam Newtoninanam (The Mathematical Elements of Physics Confirmed by Experiments. Or, Introduction to Newtonian Philosophy) (1720-1721) came out almost simultaneous in English and went through numerous editions during his lifetime. The abridged version meant for his students, Philosophiae Newtonianae institutiones, appeared in 1723 and went through several editions as well. In 1727 he published Matheseos universalis elementa (Dutch ed., 1728; English ed., 1752), and when he began lecturing on philosophy, he published an Introductio ad philosophiam, metaphysicam et logicam continens (1736), which went through a number of editions.

‘s Gravesande was a generalist who made few original contributions to science, yet he was perhaps the most famous scientist in Europe. In 1721 and 1722, he made visits to Kassel to examine a perpetual motion machine constructed by a certain Orffyreus (and concluded that apparently perpetual motion machines were possible). ‘s Gravesande declined invitations from Peter the Great of Russia (1724) and Frederick II of Prussia (1740) to join their academies. He was also immensely productive. Under his care two editions of Christiaan Huygens’s theretofore unpublished works were prepared, Opera Varia in 1724 and Opera Reliqua in 1728. He also saw to the publication of Newton’s Arithmetica, John Keill’s Introductiones ad veram Physicam et veram Astronomiam, and the first four volumes of the Amsterdam reprint series of Ouvrages adoptés par l’Académie Royale des Sciences avant son renouvellement en 1699.
