50 Most Important Women in Science

50 Most Important Women in Science

The gender gap in STEM is a complex issue with many interrelated causes. Some argue that there are fewer women who are genuinely interested in STEM careers. While there is some truth to this, we can never deny that discrimination and sexism are big hurdles. The case of Emmy Noether, an unsung hero in maths and physics, demonstrates this. Discrimination was so intense during her time that she was blocked from having a teaching position at the University of Göttingen by influential male members of the faculty. Nevertheless, she pushed on even teaching for free during her first years without holding any official position. Her lectures were promoted under David Hilbert's name and it was made out to be that she would only be "assisting." Despite this being a constant theme in her life, even enduring an unpaid professorship position, she stayed the course and made great contributions to mathematics and mathematical physics.

Emmy Noether's story illustrates that the journey of women in science is one that is full of challenges. The road to success is paved with issues such as discrimination and sexism. As one author puts it, these issues were primarily driven by the assumed superiority of the male sex (Mozans, 2015). Moreover, women's long trek to recognition in the scientific community did not begin in modern times. Hypatia, who lived between 350 to 370 CE, was one of the earliest recorded mathematicians in history (Ignotofsky, R., 2016). And, just like many of those who came after her, she paid the ultimate price for pursuing her science.

This document will take a deeper look at the 50 most important women in science since the 19th century in no hierarchical order. In this list of important female scientists, please note that it will take into account their fields of expertise, their contributions that made a global impact, the recognitions they have received, as well as positions they have held or currently hold in their current organizations. It is also the goal of the article to promote equality between men and women in science, especially in the academe. Additionally, it aims to encourage young women to take career paths in science, technology, engineering, and mathematics.

Most Important Women in Science

  1. Women in Natural Sciences
  2. Women in Formal Sciences
  3. Women in Applied Sciences

These days, the role of women in the scientific community has evolved from being ignored and undermined to one of recognition and fame. But women in science even today are far from achieving equal footing with their male counterparts in places such as the academe, where women applying for faculty positions still have problems competing with more accomplished men (Ceci & William, 2018). Still, this has not fazed female scientists from pursuing their goals, continuing to discover and innovate for the common good.

A majority of researchers in STEM are still men. Even with the increasing demand for more researchers in science, policies and programs encouraging women to take up careers in STEM are still limited. As such, only 29.3% of the total researchers in the world are female (full-time and part-time).

Fortunately, many female scientists are already achieving great things in science while working alongside their male counterparts. They serve as role models for young female scientists to continue their careers in STEM. In fact, among the highest paying jobs for women, most roles are related to STEM. Below are the 50 famous women in science whose contributions need to be acknowledged.

The Future of Women in STEM

While women have not received their rightful recognition in science, they have faithfully worked alongside their male counterparts in the name of scientific curiosity. They have worked as assistants, wives, or students who are often significant contributors to various achievements without the promise of well-deserved honors or acknowledgments like those included in the ranks of famous women scientists.

Many of them missed the opportunity to win prestigious awards, such as the Nobel Prize. They could have put up their own research teams, or could have pondered, "What is a catchy name?" for a scientific endeavor. Throughout history, only 46 women have won the Nobel Prize, 16 for their notable contributions to research; the other 30 female Noble laureates were from the fields of peace, literature, and economics (Modgil et al., 2018). And yet, they have continued to push their fields and disciplines forward. 

Various issues still plague the involvement of women in science, especially in the academe. The gender pay gap (UNESCO, 2016), various gender politics, and the general culture of STEM education are still significant issues that often discourage young and experienced scientists alike to achieve their best work. However, steps are being taken to prevent biases, especially when reviewing works of women or people of color, such as double-blind peer reviews (Etkin, 2017). Various studies are also conducted on why there are so few women in STEM in order to implement new policies to encourage more young women to consider such careers (Hill, 2010).
