Matilda effect

The Matilda effect is a bias against acknowledging the achievements of women scientists whose work is attributed to their male colleagues. This phenomenon was first described by suffragist and abolitionist Matilda Joslyn Gage (1826–1898) in her essay, "Woman as Inventor" (first published as a tract in 1870 and in the North American Review in 1883). The term "Matilda effect" was coined in 1993 by science historian Margaret W. Rossiter.^[1][2]

Rossiter provides several examples of this effect. Trotula (Trota of Salerno), a 12th-century Italian woman physician, wrote books which, after her death, were attributed to male authors. Nineteenth- and twentieth-century cases illustrating the Matilda effect include those of Nettie Stevens,^[3] Lise Meitner, Marietta Blau, Rosalind Franklin, and Jocelyn Bell Burnell.

The Matilda effect was compared to the Matthew effect, whereby an eminent scientist often gets more credit than a comparatively unknown researcher, even if their work is shared or similar.^[4][5]
