Introduction
When talking about gender discrimination in science, it becomes impossible not to allude to historic episodes of pioneering women who were discriminated against based on gender premises and to their fight to pursue careers in science—for what they meant at the time and for what they represent for women's participation today. The struggles and successes of those women against gender discrimination are important to keep alive, to remind us that the path for women in science has not always been easy, but, most importantly, that gender inequalities are possible to overcome if women unite to fight for their rights.
I will start with some stories about the experiences of prominent women scientists in the twentieth century, illustrating the challenging realities they faced at the top of the profession despite their outstanding contributions scientists. I come back to this point in the second part of this paper, when describing the context in Portugal where women faced similar realities, and where a strong domestic ideology continued until almost the end of the twentieth century. These accounts, and the numbers from national and international reports that I will show here, speak to the discriminatory environment for women in achieving recognition of their merits that continues today, and the low status that women, compared to men, have long faced in science.
Limited access and lack of recognition
On 5 July 1934,
Gender discrimination in science has historical, cultural and social roots. Only rarely have women scientists been truly recognized for their contributions, wisdom and brilliance. Of the 954 individuals who received Nobel Prizes over 120 years, only 53 have been women—just 5.6%. As Santos et al. (1991) discuss, certain circumstances illustrate well that this gender discrimination cannot be considered ‘accidental’. Whether in getting an education, competing for positions, or achieving recognition through awards, being female downgraded women's standing and visibility in science. Perhaps the best known example is the failure to elect Marie Curie to the French Academy of Sciences in 1911: although she already held two Nobel Prizes, she was overlooked in favour of the less-deserving Edouard Branly. Owing to sexism in academia, she had already been denied a place at Kraków University on her return to Warsaw in 1894, despite holding two degrees from Sorbonne University (see Goldsmith, 2005). Another well-known case is that of Rosalind Franklin (1920–1958), who earned a PhD at the University of Cambridge in 1945. In her short lifetime, she produced research that was helpful in the discovery of the structure of DNA, which led to Watson and Crick winning a Nobel Prize. However, her contributions to this discovery were not recognized, leaving her in the shadow of the discovery (see Maddox, 2002). Similarly, Jocelyn Bell-Burnell (1943–) discovered the first pulsars in 1967 as a graduate student but did not receive the Nobel Prize in physics awarded for this discovery in 1974 (Hewish et al., 1968). Her story is portrayed in a recent video (see Proudfoot, 2021).
These stories illustrate the hostile environment for women in science over the years at the highest level. Yet perhaps the most important lesson from these stories is what these women represent: they represent a mark in science and in the history of women in science. They break with the idea of science made by men and for men, of the ‘gentlemen of science’ (Cohen, 1998), and of competitive, aggressive environments in which only men can triumph. They represent pioneering steps towards gender equality in science, and their legends go far beyond their extraordinary scientific achievements. They symbolize perseverance and the courage needed to bear environments closed to women, to stand their ground and fight for the rights of generations to come. These strengths have certainly affected the role of women in science today, which is evidenced in the growing number of female scientists who have had opportunities and have made science their careers.
A ‘turn’ in the numbers in the twenty-first century
I will now briefly review global and European trends of women in science to evidence the progress achieved in opening the door of science to women, but also point to some details in the numbers of women researchers to show that, behind this opening, challenges for women remain.
High increase in female researchers worldwide
Global indicators over recent decades undeniably point to the increase of women's level of education and participation in science, in all areas of research. In the early twentieth century, women were barely represented among scientists holding PhD degrees. Today, however, women account for 44% of doctorate holders (OECD, 2022) and 33% of researchers 3 worldwide (UNESCO, 2020a). According to data from the UNESCO Institute for Statistics 4 for 107 countries covering the years from 2015 to 2018, this proportion of researchers is higher than five years ago (28.4%). However, this representation is not equal across global regions. The regional averages for the share of female researchers are higher for Central Asia (48.5%), Latin America and the Caribbean (45.8%), Arab states (40.9%), Central and Eastern Europe (39.0%), North America and Western Europe (32.9%), contrasting with sub-Saharan Africa (31.1%), East Asia and the Pacific (25.0%), or South and West Asia (23.1%), where the share of women in research is lower (UNESCO, 2020a). Despite some limitations (for example, some countries do not collect relevant data regularly), 5 the available data from various sources confirms a trend towards achieving gender parity in research. However, the data also shows differences in the areas in which women show higher representation: physics, mathematics and engineering are less popular among women, whereas health and welfare, social sciences and journalism, and arts and humanities are more popular, with female representation reaching about 80% in some disciplines and countries (UNESCO, 2020a).
In Europe, the share of female researchers in higher education is relatively high. Countries such as Lithuania (50.7%), Latvia (52.4%), Bulgaria (52.8%) and Portugal (51.3%) have the highest shares of women in science, whereas Italy (40.4%), Denmark (44%), Malta (35.8%) and Hungary (37%) have lower shares. The numbers are even higher for the share of women in science and technology positions overall (including other sectors than higher education).
Low representation of female scientists in top positions
Looking at the aggregate numbers, gender parity appears to have been largely achieved. However, this masks the underlying issue of women being poorly represented in senior positions and in top management roles.
In 2000, the European Commission commissioned an important report on women and science to an independent Expert Working Group (European Technology Assessment Network for Women and Science, ETAN). 6 The study, the first of such type, aimed to assess the position of women in science in Europe. The report showed that women were very poorly represented in senior positions in countries such as the Netherlands (5.0%), Belgium (5.1%), Switzerland (5.7%), Germany (5.9%) and Austria (6.0%). Even in countries with higher percentages of females in senior positions, women's representation was still low: Finland (18.4%), Portugal (17%), Australia (14%), the United States (13.8%) and France (13.8%) (European Commission, 2000). Twenty years later, the numbers have changed little. According to UNESCO data for 2018, women made up 43% of teachers in universities but held only 18% of top management roles. The male–female divide is even wider in school governance and education policymaking (UNESCO, 2020a). For example, in 2020, only 15% of rectors in the European University Association (EUA) were female, compared to 85% males, and this represented an increase of 38% from the proportion of female rectors in 2014 (EUA, 2020).
Also, these numbers tell us little about the conditions in which scientific researchers, including women, work, are integrated and are promoted. A study by the Organisation for Economic Co-operation and Development (OECD, 2022) showed that around 90% of the researchers in OECD countries were in precarious, short-term contracts and fellowships. Most do not enter academic careers, and those that do have difficulty progressing (OECD, 2022). The numbers clearly indicate that women in science still contend with inferior standing compared to men. I will come back to these points later in this paper, as this also reflects the context in Portugal.
I will now turn to focus on these issues in the Portuguese context by briefly talking about the evolution of women in the scientific profession, presenting short historical accounts and reporting national statistics.
Women's participation in science in Portugal
In Portugal, the participation of women in science has followed the general trends outlined above: a period of strictly no access and recognition followed by growth in the numbers of women doing science but with a persisting problem of low status in the profession. Yet, compared to women in many other countries, those in Portugal were late in entering all professions (Ferreira, 1986), and science was no exception. This is largely attributable to the New State (
The first female admission to a Portuguese university and the first award of a higher academic degree to a woman took place very late. The University of Coimbra (established in 1290 and among the oldest in Portugal) did not admit a female student until 1891, when Domitila de Carvalho was permitted to enrol in mathematics (Carvalho, 2004; Gomes, 1991), and did not award a PhD to a woman until as late as 1965, when Seomara Da Costa Primo of the Faculty of Sciences became the first female recipient. In the University of Lisbon, the first woman to earn a PhD was Maria Manuela da Gama Figueiredo Assalino in 1939 (Santos et al., 1991).
Perhaps ironically, in the early years of
Although these were not good times for women, they were not silent. Many Portuguese women manifested concern over female emancipation. One notable figure was Carolina Beatriz Ângelo (1878–1911). She was a medical doctor and the first female surgeon in Portugal, which was against the strongly sexist preponderance of male surgeons at the time. She became the first woman to vote in Portugal in 1911 by invoking her status as head of the household after being widowed (prompting a change in electoral legislation to block women from voting).

Ângelo was a feminist involved in many initiatives, including the Republican League of Portuguese Women (
Despite the dark years for women under the
The precipitous rise of women into science since the 1990s
In 1950, around 42% of the Portuguese population was illiterate (the percentage among women was even higher), and only 0.04% of the Portuguese population had completed university degrees (Gonçalves, 2003). This picture changed quickly after 1975, and more so over more recent decades. In 2021, less than 2% of Portuguese citizens were analphabetic, with women accounting for 68% of these individuals (Instituto Nacional de Estatística, INE, 2022). Moreover, in 2020, 33% of women in Portugal had higher education degrees, compared to 28% of men. This reflects significant increases on the respective percentages of 20% and 14% recorded in 2011 (INE, 2022) but also indicates a ‘turn’ in which the percentage of women with degrees surpassed that of men. Nevertheless, researchers made up about 1% of the active population in 2020, up from 0.8% in 2012.
In terms of women's participation in science, Portugal has become an international exemplar of gender balance. As noted above, the percentage of women employed in science is higher in Portugal than in many other countries. Portugal also stands out for the representation of women among science students, which has been quite stable at over 50% during the past decade (UNESCO, 2020b). National data (Figure 1) shows that female students have consistently accounted for over half of all students in higher education institutions, including both universities and polytechnics, since 1990 (DGEEC, 2022a).

The number of women scientists has also significantly increased over recent decades, moving close to parity with male scientists. According to national statistics, the number of researchers in public universities rose from 24,296 in 2001–2002 to 30,372 in 2021–2022, when the female proportion was around 46% (Table 1, INE, 2022). However, it is important to note that many researchers have temporary contracts, and only a small percentage are integrated into academic careers or hired as ‘academic staff’ in universities (with permanent contracts). Between 2017 and 2021, 64% of researchers (not ‘academic staff’) in Portugal were employed under temporary contracts; this refers to all those who are not ‘academic staff’ (DGEEC, 2021). Although this issue affects both men and women, the impact on women is greater as they are more concentrated in postdoctoral and lower-level positions.

The research community in Portugal seems to be fragmented, with two parallel career paths: academics in universities (academic staff who also conduct research) and ‘entrepreneur’ researchers working in universities and other scientific institutions on temporary contracts. A few institutions have created a separate career track for researchers in universities, but this development is very recent and the outcomes are unknown.
Despite very positive trends in the total number of women in science education and research, Portugal is similar to other countries in lacking gender equality in top-level positions, particularly full professorships and in management and decision-making roles in higher education. Jesuíno et al. (1995) showed that, in the late 1990s, only 17% of full professors in Portuguese universities were women. More recent data shows that after 20 years there has been little change.
Figure 2 illustrates the overall underrepresentation of women in all three levels of professorship, and the gap widens as we ascend the hierarchy. Even the low-ranking positions are still dominated by men, although there has been progress towards parity at this lower level in recent years. In 2001, 39.2% of assistant professors were women, and in 2012 that proportion was 46%. In 2022, only 37% of associate professors and just 25% of full professors were women (DGEEC, 2022b). Figure 3 also shows the very limited representation of women in Portuguese university rectorates: only in 2000 was the first woman appointed to a rectorate, and the total number of women in rectorates did not exceed two until 2018 (INE, 2022).

The stories of women presented here and the national and international numbers show the astonishing progress made in tackling gender discrimination worldwide. Gender equality has become part of European and national policies and organizations that aim to promote equal participation and opportunities for women and men, especially in access to education, science and scientific decision-making. But they also show that gender discrimination in science has been present since women have been doing science. The old problem in recognizing women's achievements and merits persists today, even in societies and in fields of research where women are in the majority.
Disfavour of women in access to science or failure to recognize their achievements based on gender premises did not promote women as scientists in society and has affected women's status for generations. Women are seen as less brilliant in science by the public—the ‘gender brilliance’ stereotype (Storage et al., 2020), which is common across the world, even in countries that are more gender-equal (Miller et al., 2015). And women are also underrepresented in careers in which success is perceived to depend on high levels of intellectual aptitude (such as brilliance or genius).
This is recognizably not a question of scientific capacity, as shown by the many examples of brilliant women who have made important contributions to the advancement of science, and no convincing evidence that women are intellectually less capable than men exists (Miller et al., 2015). Why is it that women continue to have a lower status in the profession, if not for the segregation of the fields by those who want to preserve their power and keep it as it has always been?
This gender discrimination is seen at two main levels, at career entry and in top positions, as shown here and points to two main problems: job insecurity and a lack of access to top positions.
The push at European and national levels to increase these numbers through schemes that involve opportunities for PhDs and postdoctoral research has been enormous, yet these initiatives seem to be detached from institutional policies to integrate young researchers into academic careers. This raises important questions about the place of PhDs in society and their role in the national scientific system and universities, and in other sectors. In Portugal, attempts to address the precarious conditions faced by scientists working in universities (the large majority) have been short-term measures, not comprehensive solutions. This represents a failure of academic and political institutions to define and implement policies to encourage recruitment of researchers in the sectors they are needed.
Women are particularly affected by the lack of recognition and the resulting limitation of their promotion prospects. This is an old problem, and confirms the persistence of a glass ceiling, under which women are generally restricted to lower-level professor positions and poorly represented at the senior management level, which continues to be dominated by men. This glass ceiling might be a more serious problem for women working in more conservative institutional cultures such as Portugal's, where institutions are characterized by conservatism and ‘academic inbreeding’ is a prominent feature (Horta, 2022). Research on gender topics continues to show that university cultures are hard to change, and in many cases are ruled by the old
The absence of women from senior positions reflects lost potential to maximize their capacities and talents. It is also problematic from a social justice and institutional perspective in terms of scientific growth, as well as an impediment to promoting deserving women. Equality in science is not yet fully achieved at many levels, but there is a path for further progress.
Finally, this story and its struggles are also mine. I am part of a generation of female scientists benefiting from the progress initiated by pioneers; I have enjoyed (competitive) opportunities to go abroad to pursue a PhD and to build a career internationally. I see how these opportunities have helped me become the researcher I am today, driving my passion for research. Yet I also see the ongoing challenges in the academic system, particularly the need to better integrate women. I am confident that these challenges can be overcome through all women speaking with one voice to government and institutions. Being recognized is a right, not a privilege. In the spirit of Lise Meitner: We do not just want a PhD degree; we also want to fulfil our full role as scientists in institutions and society.
