History was written primarily by men, about men. But behind every great leap of human progress, there are extraordinary women whose contributions were minimized, stolen, or simply forgotten.
In this article, we'll meet 10 women who changed the course of history — and who deserve to be remembered and celebrated.
1. Rosalind Franklin (1920–1958) — The True Discoverer of DNA
Rosalind Franklin was a British chemist and X-ray crystallographer whose work was fundamental to the discovery of DNA's structure. Her famous "Photo 51," obtained through X-ray diffraction, revealed the double helix structure of DNA.
However, her colleagues James Watson and Francis Crick used her data without permission and received the Nobel Prize in 1962. Franklin had died of ovarian cancer at age 37, possibly caused by radiation exposure during her experiments. She never received proper credit during her lifetime.
Today, Rosalind is recognized as one of the most important scientists of the 20th century. Her work not only revealed DNA's structure but also contributed to the understanding of viruses like the tobacco mosaic virus and poliovirus.
2. Marie Curie (1867–1934) — Pioneer of Radioactivity
Marie Curie was the first woman to win a Nobel Prize and the only person in history to win the prize in two different scientific fields: Physics (1903) and Chemistry (1911).
Born in Poland as Maria Sklodowska, she faced enormous barriers. Women couldn't attend universities in Warsaw, so she studied clandestinely before moving to Paris. There, she discovered two chemical elements — polonium and radium — and coined the term "radioactivity."
During World War I, Marie developed mobile X-ray units called "Petites Curies" that saved thousands of lives on the battlefields. She died in 1934 from aplastic anemia caused by prolonged radiation exposure. Her laboratory notebooks are still so radioactive that they must be stored in lead-lined boxes.
3. Ada Lovelace (1815–1852) — The First Programmer in History
More than a century before modern computers, Ada Lovelace wrote what is considered the first algorithm in history, designed to be processed by a machine.
Daughter of the poet Lord Byron, Ada was educated in mathematics and science at her mother's insistence, who feared she would inherit her father's "poetic madness." At 17, she met Charles Babbage and his Analytical Engine, a mechanical computer project.
Ada didn't just translate an article about the machine — she added her own notes that were three times longer than the original text. In those notes, she described how the machine could manipulate symbols beyond numbers, anticipating programming concepts that wouldn't be developed for another century.
The programming language "Ada," created by the U.S. Department of Defense in 1980, was named in her honor.
4. Malala Yousafzai (1997–present) — The Voice of Girls' Education
At age 15, Malala Yousafzai was shot in the head by the Taliban for defending girls' right to education in Pakistan. She not only survived but transformed her tragedy into a global platform.
Since age 11, Malala had been writing a blog for the BBC under a pseudonym, documenting life under Taliban rule in the Swat Valley. After the attack in 2012, she became a worldwide symbol of the fight for education.
In 2014, at age 17, she became the youngest person ever to receive the Nobel Peace Prize. Her foundation, the Malala Fund, has invested millions of dollars in educational projects in countries like Pakistan, Nigeria, India, and Brazil.
Today, more than 130 million girls worldwide are still out of school. Malala's work remains more relevant than ever.
5. Wangari Maathai (1940–2011) — The Woman Who Planted Trees
Wangari Maathai was a Kenyan biologist who founded the Green Belt Movement in 1977, an initiative that planted more than 51 million trees across Africa.
The first woman in East Africa to earn a doctorate, Wangari realized that deforestation was causing soil erosion, water scarcity, and poverty in rural communities. Her solution was simple and brilliant: pay women to plant trees.
The movement faced brutal resistance from the Kenyan government. Wangari was arrested, beaten, and threatened with death multiple times. But she persisted, and the Green Belt spread across the entire continent.
In 2004, she became the first African woman to receive the Nobel Peace Prize, recognizing her contribution to sustainable development, democracy, and peace.
6. Hedy Lamarr (1914–2000) — The Actress Who Invented Wi-Fi
Hedy Lamarr was one of Hollywood's most famous actresses in the 1940s, but few knew she was also a brilliant inventor.
During World War II, Hedy co-invented a "frequency hopping" communication system designed to prevent guided torpedoes from being intercepted by the Nazis. The patent was registered in 1942, but the American Navy ignored the invention at the time.
Decades later, frequency hopping technology became the foundation for Wi-Fi, Bluetooth, and modern military communications. Hedy only received recognition for her invention in 1997, three years before her death.
Her story is a reminder of how female talent was systematically ignored, even when their contributions changed the world.
7. Frida Kahlo (1907–1954) — Art as Revolution
Frida Kahlo transformed pain into art and became one of the most recognized cultural icons in the world. After a bus accident at age 18 that left her with permanent injuries, Frida began painting during her recovery.
Her self-portraits are brutally honest, exploring themes like identity, chronic pain, motherhood, and the female experience. In an era dominated by male artists, Frida created a unique visual language that blended surrealism with Mexican culture.
Beyond being an artist, Frida was a political activist. She was a member of the Mexican Communist Party and used her art to challenge social norms about gender and sexuality.
Today, Frida is a symbol of female resistance, and her works are the most valuable in Latin American art, with paintings selling for over 30 million dollars.
8. Katherine Johnson (1918–2020) — The Mathematician Who Sent Man to the Moon
Katherine Johnson was an African American mathematician at NASA whose calculations were essential to the success of American space missions, including the Moon landing.
In an era of racial segregation in the United States, Katherine faced double discrimination: for being a woman and for being Black. Even so, her brilliance was so evident that astronauts refused to fly without her personally verifying the computer calculations.
John Glenn, before becoming the first American to orbit Earth in 1962, said: "If she says the numbers are right, then I'm ready to go." Katherine calculated by hand the trajectory that sent Glenn into space.
Her story was told in the film "Hidden Figures" (2016). In 2015, at age 97, she received the Presidential Medal of Freedom, the highest civilian honor in the United States.
9. Emmeline Pankhurst (1858–1928) — The Leader of Women's Suffrage
Emmeline Pankhurst led the British suffragette movement that won women the right to vote in the United Kingdom. Founder of the Women's Social and Political Union (WSPU), she adopted civil disobedience tactics that included hunger strikes, demonstrations, and even property destruction.
Emmeline was arrested multiple times and subjected to force-feeding during hunger strikes in prison. Her most famous quote summarizes her philosophy: "Deeds, not words."
The suffragette movement faced police violence, press ridicule, and fierce political opposition. But in 1918, British women over 30 won the right to vote, and in 1928, full equality was achieved.
Emmeline's legacy inspired feminist movements around the world and paved the way for women to participate in political life in dozens of countries.
10. Tu Youyou (1930–present) — The Scientist Who Saved Millions
Tu Youyou is a Chinese pharmacologist who discovered artemisinin, the most effective treatment against malaria, saving millions of lives worldwide.
In the 1960s, during the Vietnam War, malaria was killing more soldiers than combat. The Chinese government launched a secret project (Project 523) to find a cure, and Tu Youyou led the research.
She studied more than 2,000 traditional Chinese medicine recipes and tested 380 plant extracts. After years of work, she discovered that the extract of Artemisia annua (a plant used in Chinese medicine for 1,600 years) was effective against the malaria parasite.
Tu Youyou tested the compound on herself before administering it to patients. In 2015, she received the Nobel Prize in Medicine, becoming the first Chinese scientist to receive the award.
It is estimated that artemisinin has already saved more than 6 million lives, primarily in sub-Saharan Africa.
What These Women Have in Common
Despite living in different eras and contexts, these 10 women share striking characteristics:
- Persistence in the face of adversity: All faced enormous barriers — gender discrimination, racism, political violence — and refused to give up.
- Underestimated contributions: Many only received recognition decades after their achievements, or never received it in their lifetimes.
- Lasting impact: Their contributions continue to influence science, politics, art, and society to this day.
Lessons from History for the Present
History is not merely a record of the past — it is an essential guide for understanding the present and anticipating the future. The events and figures explored in this article offer valuable lessons that remain relevant centuries later. Patterns of human behavior, power dynamics, and economic cycles repeat throughout history, and recognizing them helps us make more informed decisions.
Modern historiography has made efforts to include voices that were historically marginalized. The history of women, indigenous peoples, enslaved populations, and other minorities is being recovered and integrated into the main historical narrative, offering a more complete and nuanced view of the past. This inclusion is not just a matter of justice but also of historical accuracy.
Technology is revolutionizing how we study and preserve history. Digitization of ancient documents, DNA analysis of archaeological remains, and virtual reconstructions of ancient cities are revealing details that were previously impossible to discover. Virtual museums and immersive experiences are making history more accessible and engaging for new generations of learners worldwide.
Historical Context and Global Repercussions
To fully understand the events described in this article, it is essential to consider them within the broader context of world history. No historical event occurs in isolation — each is the result of a complex web of causes and consequences that extend across decades or even centuries of human civilization.
The repercussions of these events continue to shape the world we live in. National borders, political systems, economic structures, and even cultural prejudices have roots in historical events that many of us are unaware of. Understanding these connections allows us to question simplistic narratives and develop a more critical view of the world around us.
The preservation of historical memory is a collective responsibility. Monuments, museums, archives, and oral traditions play complementary roles in maintaining historical knowledge. In the digital age, new forms of preservation are emerging, from online databases to oral history projects that capture testimonies of witnesses to important events before their voices are lost forever.
Forgotten Figures Who Changed the World
History is often told through the actions of great leaders and public figures, but many of the most significant transformations were driven by ordinary people whose names rarely appear in textbooks. Inventors, activists, scientists, and anonymous artists contributed in fundamental ways to the progress of humanity, and their stories deserve to be recovered and celebrated by future generations.
Oral history plays a crucial role in preserving these marginalized narratives. Projects that collect testimonies from war survivors, immigrants, and members of traditional communities are creating invaluable archives that complement official records. These voices offer unique perspectives on historical events that formal documents frequently ignore or distort in their official accounts.
Archaeology continues to reveal surprises that rewrite entire chapters of human history. Recent discoveries of lost civilizations in the Amazon, submerged cities in the Mediterranean, and prehistoric sites in Africa are showing that our ancestors were far more sophisticated than we imagined. Each excavation has the potential to completely transform our understanding of the past and challenge long-held assumptions.
Wars, Conflicts, and Their Lasting Consequences
Armed conflicts have shaped the political map of the world in profound and lasting ways. From the wars of antiquity to modern conflicts, each confrontation has left scars that persist for generations. Understanding the causes and consequences of these conflicts is essential to preventing the mistakes of the past from being repeated in the future.
Diplomacy and international organizations emerged as responses to the devastation caused by world wars. The United Nations, the European Union, and other multilateral bodies represent humanity's attempts to resolve disputes through peaceful means. Although imperfect, these institutions have contributed to the longest period of relative peace between major powers in modern history.
The memory of conflicts is preserved in various forms around the world. Memorials, museums, films, and literary works ensure that the lessons learned from suffering are not forgotten. Education about the history of conflicts is fundamental to forming conscious citizens committed to peace and social justice in an increasingly interconnected world.
Frequently Asked Questions
Why were so many important women forgotten by history?
Traditional historiography was dominated by male perspectives for centuries. Female contributions were frequently attributed to men, minimized, or simply not recorded. Recent historical revision movements are rescuing these narratives.
Which of these women had the greatest impact on science?
It's difficult to compare, but Marie Curie and Tu Youyou had enormous measurable impacts. Curie opened entire fields of physics and chemistry, while Tu Youyou's discovery directly saved millions of lives.
Are there Brazilian women who changed history?
Yes, many. Dandara dos Palmares led resistance at Quilombo dos Palmares. Nise da Silveira revolutionized psychiatric treatment in Brazil. Bertha Lutz led the Brazilian suffragette movement. Maria da Penha inspired the law that protects women against domestic violence.
How can I learn more about women in history?
Books like "Invisible Women" by Caroline Criado Perez and "Women in Science" by Rachel Ignotofsky are great starting points. Documentaries and podcasts about women's history are also increasingly accessible.
What the Numbers Say About Gender Equality
Despite progress, gender equality is far from being achieved:
Global Gender Gap Report 2025 (World Economic Forum): At the current pace, gender equality will be achieved in... 131 years. Iceland leads the equality ranking (for the 15th consecutive year). Brazil ranks 94th among 146 countries.
Science: Women make up 33% of researchers worldwide (UNESCO), but receive only 3% of science Nobel Prizes. Marie Curie won two — in 1903 (Physics) and 1911 (Chemistry) — and to this day only 25 women have received Nobel Prizes in science.
Politics: In 2025, only 28% of parliamentarians worldwide are women. In Brazil, women hold 18% of seats in the Chamber of Deputies — despite being 52% of the population.
Technology: Women represent only 22% of the AI workforce globally. In tech leadership positions, the number drops to 5% at the largest companies. The lack of diversity affects products: facial recognition algorithms have significantly higher error rates for Black women.
Women Changing the World Today
The new generation of women leaders includes Ngozi Okonjo-Iweala (first woman and African to lead the WTO), Katalin Karikó (2023 Nobel laureate, fundamental to mRNA vaccines), Francesa Donner (CEO of Unilever), and in Brazil, Tabata Amaral and Priscila Cruz (education), Luiza Trajano (business), and Jaqueline Goes de Jesus (who sequenced the SARS-CoV-2 genome in record time).
