5. Leonardo da Vinci (1452–1519) – Italy: Born on April 15, 1452, in Vinci, a small town near Florence, he was one of the most prominent figures of the Renaissance, a symbol of the ideal of the “universal man” who mastered multiple fields of knowledge. His life was a constant search for knowledge, guided by an inexhaustible curiosity and a profound observation of nature.
Leonardo was a painter, sculptor, engineer, anatomist, architect, musician, botanist, geologist, and more. Despite not having received a formal university education, his self-taught ability allowed him to explore and excel in fields that are still highly specialized today.
His most famous work is the Mona Lisa (La Gioconda) , known for its mysterious smile and sfumato technique. He is also the author of The Last Supper , one of the most influential religious compositions in Western art. However, his genius went beyond art: he filled more than 7,000 pages of notebooks with anatomical studies, designs for flying machines, bridges, weapons, hydraulic systems, and scientific studies that were ahead of their time.
Leonardo conceived of science and art as interconnected. His study of the human body, for example, was both anatomical and artistic. He believed that understanding the workings of nature was fundamental to creating beauty.
Leonardo left an indelible mark on human history. He was a pioneer in accurately depicting the human body, in conceiving flying machines long before the existence of aviation, and in imagining a science based on direct observation, not just tradition. His example demonstrates that knowledge should have no boundaries, and that curiosity can be humankind's greatest creative force.
He died on May 2, 1519 in Amboise, France, at the castle of Cloux (today Clos Lucé), protected by King Francis I, who deeply admired him.
Famous quote: “Learning never exhausts the mind.”
6. Martin Luther King Jr. (1929–1968) – United States
Martin Luther King Jr. was born on January 15, 1929, in Atlanta, Georgia, at a time when racial segregation was legal and common in much of the American South. The son of a Baptist minister, he trained as a Protestant minister and earned a doctorate in systematic theology from Boston University.
Inspired by Mahatma Gandhi's principles of nonviolence and his Christian faith, King became the face of the civil rights movement in the United States during the 1950s and 1960s. His struggle focused on achieving legal and social equality for the African American population, without resorting to hatred or violence.
In 1955, she led the famous Montgomery bus boycott following the arrest of Rosa Parks, marking the beginning of her national leadership. Her impassioned oratory, deep spiritual conviction, and courage in confronting injustice mobilized millions.
He was arrested more than 20 times, physically assaulted, and the constant target of threats. However, he never renounced nonviolence as a moral and political strategy. He organized marches, sit-ins, and peaceful protests in cities such as Birmingham, Selma, and Washington, D.C.
Historic Speech: On August 28, 1963, in front of the Lincoln Memorial, he delivered his most famous speech, “I Have a Dream,” before more than 250,000 people. His vision of a society where Black and white children played together as equals moved the world.
Famous quote: “Darkness cannot drive out darkness: only light can do that. Hate cannot drive out hate: only love can do that.”
Recognition: In 1964, he received the Nobel Peace Prize, becoming the youngest recipient at the time. His efforts helped lead to the passage of key laws such as the Civil Rights Act (1964) and the Voting Rights Act (1965).
Tragic death and legacy: On April 4, 1968, he was assassinated in Memphis, Tennessee, while supporting a sanitation workers' strike. His death sparked a wave of protests across the country. Since then, he has been recognized as one of humanity's great heroes.
In the United States, Martin Luther King Jr. Day is celebrated on the third Monday of January each year. His legacy continues to inspire generations around the world to champion equality, social justice, and human rights.
Maria Sklodowska: Born on November 7, 1867, in Warsaw, Poland, under Russian rule. From a very young age, she demonstrated exceptional intelligence, but as a woman in 19th-century Europe, she faced barriers to higher education. She emigrated to Paris and adopted the name Marie Curie, where she entered the Sorbonne University and graduated with honors in Physics and Mathematics.
There she met Pierre Curie, her husband and fellow scientist. Together they began research into the radiation discovered by Henri Becquerel. In 1898, they announced the discovery of two new elements: polonium (named after her native Poland) and radium.
Marie Curie coined the term "radioactivity" and developed pioneering methods for isolating radioactive elements. Her work forever changed physics, chemistry, and medicine.
Nobel Prize: Physics (1903): shared with Pierre Curie and Henri Becquerel, for their research on radiation. She was the first woman to receive a Nobel Prize.
Nobel Prize in Chemistry (1911): for the isolation of radium and his studies on polonium. He was the only person to win a Nobel Prize in two different scientific fields.
Contributions to medicine and warfare:
During World War I, she developed mobile X-ray units (known as "Little Curies" ) to assist in the treatment of wounded soldiers. She drove ambulances to the front herself, without radiation protection, which subsequently affected her health.
Famous quote: “Nothing in life is to be feared, only understood. Now is the time to understand more, in order to fear less.”
Legacy: Marie Curie broke gender, social, and scientific barriers. She was the first female professor at the University of Paris, founded the Curie Institute (now one of the leading cancer research centers), and her work laid the foundation for nuclear medicine and cancer treatments.
She died on July 4, 1934, of aplastic anemia caused by her prolonged exposure to radiation. She was buried next to Pierre in the Panthéon in Paris, the resting place of France's great heroes—the first woman to receive this honor in her own right.
8. Albert Einstein (1879–1955) – Germany / USA
Beyond the theory of relativity, he left an ethical and human legacy of peace, education, and freedom.
Albert Einstein was born on March 14, 1879, in Ulm, Germany. From childhood, he displayed a great curiosity about the universe and a strong critical sense. Although he was slow to speak and had an unconventional learning style, his mind was notable for its abstract and imaginative thinking.
In 1905, at the age of 26, he revolutionized the world of science with his Special Theory of Relativity , introducing the famous equation E=mc² , which reveals the equivalence of mass and energy. This was just the beginning of a brilliant scientific career.
In 1915, he formulated the General Theory of Relativity , a completely new description of gravity that changed our understanding of time, space, and the cosmos. In 1921, he received the Nobel Prize in Physics , not for relativity, but for his discoveries concerning the photoelectric effect , which paved the way for quantum physics.
Exile and life in the US: Einstein was a staunch opponent of Nazism. Being Jewish and a pacifist, he was forced to flee Germany in 1933 and settled in the United States, where he worked at the Institute for Advanced Study in Princeton.
Although he warned about the possible destructive use of nuclear energy (as in his 1939 letter to Roosevelt), Einstein did not participate in the Manhattan Project . He later became an advocate for world peace, nuclear disarmament, and understanding among peoples.
Famous quote: “The mind is like a parachute: it only works if it’s open.”
Humanism and social commitment: Einstein was much more than a scientist. He was a civil rights activist (he publicly defended African Americans), a critic of authoritarianism, and a profound ethical thinker. He supported the creation of the State of Israel, but also advocated for peaceful coexistence with the Arab peoples.
As a thinker, he wrote about the importance of free education , imagination , scientific responsibility , and the need for a world government to prevent wars .
Legacy: Einstein is a symbol of scientific genius, but also of the intellectual committed to the common good . His figure has been an inspiration to generations of scientists, educators, and dreamers. He died on April 18, 1955, leaving behind a legacy that transcends the scientific field and continues to influence ethical debates in today's world.
9. Simone Weil (1909–1943) – France: Philosopher, mystic, and activist. Her profound thought united faith, social commitment, and sensitivity to human suffering. She was born in Paris in 1909 to an agnostic, intellectually brilliant Jewish family. From a young age, she displayed exceptional intelligence, a strong moral conscience, and profound compassion for the weak. She studied at the École Normale Supérieure, one of France's most prestigious institutions, where she was a classmate of the philosopher Albert Camus and a disciple of Alain.
From a young age, she was a radical advocate for workers and the poor . Instead of limiting herself to academic teaching, she decided to experience workers' suffering firsthand and worked as a factory worker. This experience informed her thinking about the dehumanization of modern work.
She was actively involved in social and political causes: she defended peasants, supported the Republic during the Spanish Civil War (though without taking up arms), and helped refugees. However, she was always critical of political fanaticism , even on the left, and remained faithful to her individual conscience.
Mysticism and faith: Although he never formally converted to Christianity, he had profound mystical experiences that influenced his thinking and work. He felt a special connection with Christ crucified, redemptive suffering, and absolute truth. His writings uniquely blend Greek philosophy, Christian spirituality, poetry, and ethics.
She dedicated herself to living a life of austerity, sometimes extreme, as a form of solidarity with those who suffered . Her ideal of justice was so radical that she rejected all privileges, even intellectual or religious ones. This ethical purity led her to live almost like a secular saint.
Famous quote: “Attention, taken in its purest form, is the same as prayer.”
Works and legacy: Although she died young, at 34, she left behind an influential body of work: "Gravity and Grace , " "Waiting for God , " "Reflections on the Causes of Liberty and Social Oppression ," among others. She was an uncomfortable, lucid, and deeply ethical thinker.
She died in England during World War II, weakened by tuberculosis and her refusal to eat more than what French soldiers received at the front.
Legacy: Simone Weil is now considered one of the most original minds of the 20th century . She was admired by intellectuals such as Camus, T.S. Eliot, and Emmanuel Lévinas. Her life and work continue to inspire those who seek to unite profound thought, true spirituality, and an uncompromising commitment to the oppressed.
10. Francis of Assisi (1181–1226) – Italy: founder of the Franciscan Order, symbol of humility, love of nature and the poor.
Born Giovanni di Pietro Bernardone in Assisi, Italy, in 1181 or 1182, he was the son of a wealthy cloth merchant. From a young age, Francis led a carefree life, dreaming of military glory. However, a series of spiritual experiences and profound illnesses led him to a radical inner change .
After publicly renouncing his inheritance, a gesture that scandalized his family and the society of his time, he dedicated himself entirely to living according to the Gospel. He embraced total poverty , wearing a simple linen habit and serving the sick, lepers, and marginalized.
In 1209, he founded the Order of Friars Minor , known as the Franciscans , whose rule was to live without possessions, preach peace and love, and serve humbly. Soon after, he also inspired women (such as Clare of Assisi) and lay people, creating a wave of renewal within the Catholic Church.
Love for creation: Francis of Assisi is also known as the “patron saint of ecology .” His love for nature was so profound that he spoke of “brother sun,” “sister moon,” and “brother wolf.” He saw all creatures as part of the same family created by God, which he beautifully expresses in his “Canticle of Creatures ,” considered one of the earliest literary texts in Italian.
His vision of the world was deeply unitary and harmonious : poverty was spiritual wealth, animals were brothers, pain was a path to grace.
Mystical life and stigmata: In 1224, during a retreat on Mount Alvernia, he received the stigmata of Christ : marks on his body that replicated the wounds of the crucifixion. He was the first saint known in history to bear these signs.
He died on October 3, 1226, in absolute poverty, lying on the bare ground, singing psalms of gratitude. He was canonized just two years later.
Famous quote: “Start by doing what is necessary, then what is possible, and suddenly you're doing the impossible.”
Legacy: Francis of Assisi left a testament to peace, brotherhood, and simplicity that has inspired believers and nonbelievers alike. His figure has transcended religions and eras, serving as a symbol of a profound spirituality, free from power, oriented toward humility, compassion, and respect for life .
In 2013, Pope Jorge Mario Bergoglio chose the name Francis in his honor, recognizing the urgency of returning to a poor, simple, and caring Church.
12. Alexander von Humboldt (1769–1859) – Germany
Naturalist and explorer. He visited Latin America and defended the
ecology and the dignity of indigenous peoples.
Born in Berlin on September 14, 1769, Friedrich Wilhelm Heinrich Alexander von Humboldt was a 19th-century scholar who combined science, art, geography, philosophy, and social commitment. The son of a Prussian noble family, he enjoyed a solid scientific education, although it was his adventurous spirit that shaped his life.
Between 1799 and 1804, he embarked on a voyage of exploration through Latin America , which took him to Venezuela, Colombia, Ecuador, Peru, Cuba, and Mexico. This scientific expedition was extraordinary in its rigor, breadth, and depth. Humboldt measured altitudes, temperatures, ocean currents, volcanoes, plants, and ecological systems, and compiled an integrated view of nature as an interconnected whole .
During his ascent of Chimborazo volcano in Ecuador, he reached one of the highest altitudes ever reached. From that experience, a revolutionary idea was born: the unity of the natural world , beyond the boundaries between disciplines.
Science and a holistic vision: Humboldt was one of the first to study climate, ocean currents, and ecosystems from a global perspective. He introduced terms like "isotherms" (temperature lines) and anticipated ecological concepts such as biomes and the interdependence of living beings.
In his monumental work, "Cosmos ," he attempted to describe the universe scientifically, but with an almost poetic approach. It was a model of interdisciplinary and aesthetic thought , where nature was understood not only through reason but also through sensitivity.
Defense of indigenous peoples and denunciation of colonialism:
During his travels, Humboldt denounced slavery , the mistreatment of indigenous peoples, and the destruction of ecosystems. He harshly criticized the racism and arrogance of European empires in the Americas. He was a friend and advisor to Simón Bolívar , and shared his vision of freedom, science, and Latin American integration.
Famous quote: “Nature is a living whole, not a mere collection of objects.”
Legacy: Humboldt inspired scientists like Darwin, writers like Goethe and Thoreau, and politicians like Bolívar. His name has been given to rivers, mountains, species, ocean currents ( the Humboldt Current ), natural parks, and universities around the world.
He was a pioneer of modern ecology , a champion of human rights, and a visionary of environmental thought. He died in Berlin in 1859, but his legacy lives on in the study of the planet and the fight for sustainability.
12. Gabriel García Márquez (1927–2014) – Colombia
Master of letters, Nobel Prize winner in Literature. His work has immortalized the magical reality of Latin America.
Gabriel García Márquez, affectionately known as “Gabo,” was born on March 6, 1927, in Aracataca, a small town in the Colombian Caribbean. He was raised by his maternal grandparents, whose stories, silences, and superstitions would profoundly influence his work. The figures of his grandfather—a liberal colonel who told him stories of war and politics—and his grandmother—a woman with a boundless imagination—formed the basis of his narrative style: a fusion of the everyday and the magical.
He studied law, but soon abandoned it to dedicate himself to journalism, a profession he would never abandon. He lived in Colombia, Mexico, France, Spain, and Cuba, and maintained close relationships with intellectuals, artists, and political leaders from around the world.
Literary work:
In 1967, García Márquez published his most famous novel, One Hundred Years of Solitude , considered one of the most important works of world literature. Set in the mythical town of Macondo , the novel is a family saga that depicts the cyclical and poetic history of Latin America: its passions, wars, dictatorships, hopes, and neglect.
The work is the pinnacle of magical realism , a narrative style in which the extraordinary is presented as part of everyday life. This literary approach made García Márquez the great chronicler of the Latin American soul .
Other notable works:
The Autumn of the Patriarch (1975)
Chronicle of a Death Foretold (1981)
Love in the Time of Cholera (1985)
Of Love and Other Demons (1994)
Memories of My Sad Whores (2004)
Nobel Prize:
In 1982, he received the Nobel Prize in Literature , becoming the first Colombian to do so. In his acceptance speech, "The Solitude of Latin America ," he made a powerful defense of the culture, history, and challenges of our continent.
Famous quote:
“Life is not what one lived, but what one remembers and how one remembers it in order to tell it.”
Legacy: Gabriel García Márquez was a bridge between Caribbean oral tradition and universal literature , between politics and poetry, between journalism and the novel. He was a friend of leaders like Fidel Castro, but also a defender of press freedom and education.
His work has been translated into more than 40 languages and has inspired generations of writers around the world. He died on April 17, 2014, in Mexico City, leaving behind a unique narrative universe where nostalgia, love, death, and the fantastic intertwine with the true history of Latin America.
