Gabriel Cramer (1704 – 1752)

Gabriel Cramer was a Swiss mathematician and professor of mathematics and philosophy at the University of Geneva. Cramer’s contributions to mathematics mostly focus on algebra and geometry in his unique book, a treatise on curves called Introduction à l’analyse des lignes courbes algébriques, which was published in Geneva in 1750. This treatise notably includes a method that is now known as Cramer’s rule to solve linear systems of equations, using what would later be called determinants.
