Pinpointing the very first female scientist is challenging due to historical record-keeping biases. Many women's contributions to science went unrecognized or undocumented for centuries. However, several candidates stand out depending on the definition of "scientist" and the time period considered.
Prominent Early Female Figures in Science

Defining "Scientist"
The term "scientist" is a relatively modern one. Early contributions to fields like astronomy, mathematics, and medicine were often made by individuals who didn't necessarily identify as "scientists" in the contemporary sense. The lack of formal recognition for women in science further complicates determining the "first."
