THE
MATILDA
EFFECT
When women’s scientific achievements are systematically misattributed to men, history loses not just individual stories—it loses entire generations of inspiration.
What is the Matilda Effect?
Coined in 1993 by science historian Margaret W. Rossiter, the Matilda Effect describes the systematic bias against women scientists whose pioneering work was either:
- Attributed to male colleagues who claimed credit
- Dismissed or ignored by the scientific establishment
- Erased from history despite groundbreaking contributions
Named after suffragist Matilda Joslyn Gage, who in 1883 first documented how women’s scientific achievements were systematically credited to men.
