Unsung Pioneers
Forgotten women in the scientific community
Throughout history, many women have made groundbreaking contributions to science, only to be overlooked or underappreciated in their time. Vera Rubin, Eunice Foote, and Lise Meitner were three such women whose work fundamentally shaped modern physics, astronomy, and climate science. Their discoveries: dark matter, the greenhouse effect, and nuclear fission, are central to our understanding of the universe, yet they did not receive the full recognition they deserved.
Vera Rubin (1928–2016) was an American astronomer whose research provided some of the first convincing evidence for the existence of dark matter. In the 1970s, Rubin and her collaborator, Kent Ford, studied the rotation curves of galaxies, expecting to find that the stars on the outer edges of galaxies moved more slowly than those near the centre in accordance with Newtonian mechanics. However, their observations revealed something astonishing: stars at the outer edges were moving just as fast as those closer to the galactic core. This was inconsistent with the distribution of visible matter and strongly suggested the presence of a massive, unseen substance — what we now call dark matter.
Despite the significance of her discovery, Rubin was overlooked for the Nobel Prize in Physics, although dark matter remains one of the biggest unresolved mysteries in astrophysics. The scientific community has since accepted her findings, and dark matter research has become one of the most active fields in cosmology. Rubin’s legacy lives on, and her work fundamentally changed our understanding of the universe’s composition.
Eunice Foote (1819–1888) was an American scientist and women’s rights advocate who was the first to demonstrate the greenhouse effect — the mechanism by which certain gases trap heat in the Earth’s atmosphere. In 1856, three years before Irish physicist John Tyndall conducted his more widely recognised work, Foote organised an experiment in which she placed various gases in glass cylinders and exposed them to sunlight. She found that carbon dioxide and water vapor absorbed heat more efficiently than other gases and retained it for longer periods. From this, she concluded that an atmosphere rich in carbon dioxide would lead to a warmer planet.
Foote’s findings were neglected for over a century, while Tyndall received credit for discovering the role of greenhouse gases. Only in recent years has Foote’s contribution been recognised, and her research is now acknowledged as a foundational step in climate science. As the world grapples with climate change, Foote’s early insight into the warming effects of carbon dioxide proves more relevant than ever.
Lise Meitner (1878–1968) was an Austrian-Swedish physicist who played a crucial role in discovering nuclear fission, the process that powers both nuclear reactors and atomic bombs. Working with Otto Hahn in the 1930s, Meitner helped interpret their experiments, which showed that uranium atoms split into smaller nuclei when bombarded with neutrons. Meitner, along with her nephew, Otto Frisch, correctly explained how this process releases an enormous amount of energy, providing the theoretical framework for nuclear fission.
Despite her contributions, Meitner was excluded from the 1944 Nobel Prize in Chemistry, which was awarded solely to Hahn. This omission is considered one of the greatest injustices in the history of the Nobel Prize. Though she was later honoured with other awards, including the naming of element 109 as meitnerium (Mt) in her honour, Meitner’s central role in nuclear fission was downplayed for much of her lifetime.
These are just some of the examples throughout history of women being overlooked in favour of their male contemporaries. We should do all we can to change our perception of the titans of scientific discovery and recognise those who have done so much but been recognised so little.
