Gabriel Cramer (1704-1752), Swiss mathematician. Cramer was a professor at the University of Geneva. His best-known work was his treatise on algebraic curves, published in 1750. Two mathematical concepts are named after him, Cramer's rule and Cramer's paradox, both to do with curves and algebraic equations.
