The Matilda effect

When women disappear from the history of science

The history of science is often told in masculine terms. Yet behind every major discovery, women have researched, experimented, and innovated, only to be forgotten. This is the phenomenon known as the Matilda Effect.

What is the Matilda Effect?

It is a phenomenon where women's contributions are minimized or credited to men.

The term was coined in 1993 by American historian Margaret W. Rossiter, in honor of Matilda Joslyn Gage, a 19th century feminist activist.

"Scientific success has long been a story of privilege, not just talent."

— Margaret W. Rossiter

Netti Stevens: American biologist who discovered the X and Y sex chromosomes; yet for a long time, they were associated with her colleague Edmund Wilson.
