Matilda effect
Bias against acknowledging the achievements of women scientists
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]

Review
Nettie Maria Stevens, American geneticist (1861-1912) was the first researcher to describe the chromosomal bases that determine sex.
She discovered, from her research with the beetle Tenebrio molitor, that chromosomes known as X and Y were responsible for determining the sex of the individual.
Stevens found that the somatic cells of the female contained 20 large chromosomes, that is, ten major pairs, while the male cells had 19 large and 1 small, that is, 9 pairs of large chromosomes and one consisting of one large and one small.
She successfully expanded the fields of embryology and cytogenetics.
Biography
In 1905, Nettie Stevens published a study that would revolutionise the world of science. Her work came to show that sex was determined by specific chromosomal bases. Nettie had worked all her life to find a place for herself in the complicated and patriarchal scientific community of the dawn of the 20th century. Although over time she was given the recognition that she deserved, her scientific work was called into question. Her health did not accompany her either since her premature death occurred when she was beginning to achieve her dreams.
Nettie Maria Stevens was born on 7 July 1861 in the North American town of Cavendish, Vermont. Her parents, Julia
