Both Cramer's ruleand Cramer's paradox, discussed below, were not completely new ideas, but Cramer contributed significantly to both. Cramer also introduced the idea of utility to mathematics. Some of Cramer's most important work concerned the **history of mathematics**, as Cramer often served as the editor of other mathematicians' writings.

Cramer was born July 31, 1704, in Geneva, Switzerland, to physician Jean Isaac Cramer and his wife, Anne Mallet. Educated in Geneva, Cramer had two brothers.
