Young Lavoisier followed in his father s footsteps, and in 1763, at the age of twenty, he became a lawyer. But it wasn t the law that captured Antoine s imagination, it was a popular-science lecture. A friend dragged him to the Jardin du Roi in Paris to watch the antics of scientific lecturer par excellence, Francois Rouelle. Lavoisier was absolutely mystified by the smoke, the flames, and the smells that highlighted the presentation. Chemistry, he realized, was his calling. Within a year Lavoisier had produced a scholarly paper on plaster of Paris and had helped to make a geological map of France. His scien-... [Pg.238]

Macquer was not, indeed, the first to introduce the phlogistic theory into France. Several prominent chemists and teachers had adopted it in their philosophy. Such were Stephen Geoffroy (1672-1731), Duhamel de Morveau (1700-1781), and Guillaume Francois Rouelle (1703-1770). Yet, by common consent Macquer is considered the most prominent and most enthusiastic French advocate of the phlogistic philosophy. Macquer was born in Paris of Scotch ancestry, followers of the Stuarts who migrated to France on the expulsion of that dynasty. The original Scotch... [Pg.442]

Guillaume Francois Rouelle Elements, Principles, and Instruments... [Pg.38]

Almost every important French chemist in the middle years of the eighteenth century attended lectures that Guillaume Francois Rouelle (1703-70) gave at the King s Garden (the Jardin du roi) in Paris. He was a lively lecturer, dismissive of the theoretical excesses of other lecturers, and anxious to make his lectures be practical demonstrations of chemical phenomena. His style was scarcely that of traditional academics. In the heat of his experiments, he would roll up his sleeves, get his hands and forearms and sometimes his face and shirt dirty, and show how chemistry was above all a science of practice. This was not just rhetoric for Rouelle, practice was a crucial part of chemistry. Rouelle had more than important theoretical ideas to communicate. He had innovative views about principles and instruments, and these views brought together concepts that Stahl had kept distinct. [Pg.38]

The Enlightenment was more than the Academy and the Jardin du roi. If Voltaire was its embodiment in person, then the great Encyclopedia of midcentury was its embodiment in print. If one talks about the encyclopedia today, different people will think of different encyclopedias. There was no such confusion in mid-eighteenth-century France. Everyone knew that the encyclopedia was the work edited by Diderot and d Alembert, the Encyclopedia, or Analytical Dictionary of the Sciences, Arts, and Trades Gabriel Francois Venel (1723-75), a pupil of Rouelle, wrote the article on chemistry. He told his readers that it was a mistake to seek to reduce chemistry to physics. Chemists had their own independent science, which could penetrate beneath the surface of things and get to their true nature, their inner essence. Physicists, in contrast, dealt only with external and accidental characteristics of bodies. Chemistry was and had to be an autonomous science, practiced by specialists. [Pg.40]

Fully assembled chemical balance belonging to Guillaume Francois Rouelle, demonstrator at the Jardin du Roi in Paris, depicted in the eighteenth-century encyclopedia published by Diderot and D Alembert. G.F. Rouelle s demonstrations inspired Antoine Lavoisier to enter chemistry. Rouelle was a firm phlogis-tonist, and in less than two decades, his former student would demolish phlogiston with the modern theory of oxidation. [Pg.287]
