As appropriate to the month when we mark International Women’s Day, our pieces have revolved around women, their achievements and barriers to their growth. This week, we look at an uncomfortable historical pattern: how many of the contributions made by women have been ignored, minimized, or credited to men. This phenomenon has a name — the Matilda Effect.
The term was coined in 1993 by historian of science Margaret W. Rossiter, who used it to describe the systematic denial of recognition to women-scientists whose work was often attributed to male colleagues. Rossiter named it after the 19th-century American activist Matilda Joslyn Gage, who had earlier observed how women’s intellectual achievements were routinely erased from public record.
In simple terms, the Matilda Effect refers to the tendency for women’s scientific or scholarly contributions to be overlooked while men receive the credit.
Why the Matilda Effect Matters
Recognition is not just about credit; it shapes opportunity.
Academic promotions, research funding, leadership roles, and history are all tied to who gets acknowledged. When women’s contributions are under-recognized, it creates a cycle in which fewer women are visible as role models for the next generation.
Young girls interested in science, technology, engineering, and mathematics often search for people who look like them in positions of intellectual authority. When those figures are missing from textbooks and public discourse, aspirations can quietly narrow.
The Matilda Effect therefore operates not only as a historical injustice but also as a structural barrier to gender equity in knowledge systems.
History’s Striking Examples
Consider Rosalind Franklin’s whose X-ray crystallography images were critical to understanding the structure of DNA and enabled the breakthrough model proposed by James Watson and Francis Crick. Yet when the Nobel Prize was awarded in 1962, Franklin — who had already passed away — received little recognition for her role.
Another well-known case is of Lise Meitner, the Austrian physicist who played a key role in explaining nuclear fission. The Nobel Prize for the discovery went solely to her collaborator Otto Hahn.
India’s own intellectual history reflects similar patterns.
Take Janaki Ammal, the pioneering botanist and cytogeneticist whose work significantly advanced plant breeding and biodiversity studies in India. Despite her groundbreaking research, she remained far less publicly known than many of her male contemporaries.
Or Anna Mani, the pioneering physicist and meteorologist whose work laid the foundation for modern meteorological instrumentation in India. She played a crucial role in standardizing weather measurement systems and advancing research in solar radiation and wind energy, contributing significantly to India’s renewable energy potential. Despite the far-reaching impact of her work, she remained relatively under-recognized outside scientific and policy circles.

Similarly, Asima Chatterjee, one of India’s foremost organic chemists, made pioneering contributions to the chemistry of natural products and anti-malarial drugs. Although widely respected within scientific circles, her name rarely appears in popular narratives of Indian science.
Signs of Change
Things are hopefully changing. An example is Tessy Thomas, often called India’s “Missile Woman.” As a senior scientist at the Defence Research and Development Organisation, she played a key role in the development of the long-range ballistic missile Agni‑V. Her journey from a small town in Kerala to leading strategic defence projects has made her an inspiration for many young women considering careers in engineering and defence research.

Another widely admired figure is Gagandeep Kang, a leading medical scientist known for her work on infectious diseases and vaccines. As the first Indian woman elected Fellow of the Royal Society in the field of biomedical science, she has become a powerful role model for girls interested in medical research and public health.
In the world of space science, Ritu Karidhal and Muthayya Vanitha gained national recognition for their leadership roles in India’s lunar mission Chandrayaan‑2 at the Indian Space Research Organisation. Their visibility during the mission helped reshape public perceptions about who leads complex scientific and technological projects.
Similarly, Nandini Harinath, another senior scientist at ISRO, became widely known after the success of the Mars Orbiter Mission, where she was part of the core navigation and mission design team.
Dr. Gagandeep Kang
What distinguishes these scientists is not only their technical expertise but also their public presence. Through lectures, interviews, and outreach programs, they actively encourage young girls to consider careers in STEM — science, technology, engineering, and mathematics.
Recognition is the first step. Structural barriers — from access to research funding to representation in leadership — still need attention.
Here is to women-scientists having their day and say in scientific research!
