Trajectory

Welcome to this site dedicated to Katherine Johnson, a NASA mathematician whose calculations were essential to space conquest. Her story illustrates the Matilda effect, the phenomenon that consists of minimizing or erasing women's contributions in science. This site highlights her journey and that of other forgotten female scientists, to better understand and combat these biases.

Who is Katherine Johnson?

Katherine Johnson (1918-2020) was an African-American mathematician and space engineer whose precise calculations were essential to NASA's early successes. Her work enabled the trajectories of historic missions, particularly those of Alan Shepard and Apollo 11, the first lunar mission. Despite the racial and sexist barriers of her time, she established herself through her expertise and contributed to American space conquest. Katherine Johnson embodies the fight for recognition of women in science and perfectly illustrates the Matilda effect.

The Matilda Effect?

The Matilda effect refers to the recurrent denial or minimization of female scientists' work in favor of their male colleagues. This phenomenon, theorized by Margaret Rossiter, highlights gender biases* in research and the need for more equitable recognition.
