Gabriel Cramer(redirected from Jean Cramer)
Born July 31, 1704, in Geneva; died Jan. 4, 1752, in Bagnoles, near Nimes, France. Swiss mathematician.
Cramer established and published in 1750 a rule for solving systems of linear equations with literal coefficients, thus laying the foundations of the theory of determinants. He also studied the theory of higher-order algebraic curves, including singular points and branches.
