 Cramer's Rule
   The Cramer of the rule is Gabriel Cramer (1704-1752), a Swiss mathematician who was a professor of mathematics at Geneva. When Cramer published his rule in 1750 he did not use determinants as they are now shown, and he gave no explanation for how he achieved the result.
It seems that Colin Maclaurin probably discovered the same rule as early as 1729, but it was not published until after his death.
Although Cramer is primarily remembered for the rule of determinants above he also worked in problems related to physics and general geometry and algebraic curves.
