Discovery of Polonium and Radium
First woman to win a Nobel Prize (and the only one to win in two sciences)
Pioneered research in radioactivity
Why She’s Great:
Curie’s groundbreaking work laid the foundation for cancer treatments and nuclear energy. She broke gender barriers in science.
🔭 4. Galileo Galilei (1564–1642)
Field: Astronomy, Physics, Mathematics
Key Contributions:
Improved the telescope
Discovered Jupiter’s moons
Supported heliocentric theory
Why He’s Great:
Often called the Father of Modern Science, Galileo’s observations challenged religious dogma and changed our view of the universe.
🧫 5. Charles Darwin (1809–1882)
Field: Biology, Natural History
Key Contributions:
Theory of Evolution by Natural Selection
On the Origin of Species (1859)
Why He’s Great:
Darwin’s theory revolutionized biology and fundamentally changed how we understand life on Earth.
💉 6. Louis Pasteur (1822–1895)
Field: Microbiology, Chemistry
Key Contributions:
Germ Theory of Disease
Pasteurization
Developed vaccines (rabies, anthrax)
Why He’s Great:
Pasteur’s work saved millions of lives and paved the way for modern medicine and hygiene.
🧪 7. Nikola Tesla (1856–1943)

Field: Theoretical Physics, Cosmology
Key Contributions:
Black hole radiation (Hawking radiation)
Popularized science through books like A Brief History of Time
Why He’s Great:
Despite battling ALS, Hawking became a global symbol of intellectual brilliance and inspired millions with his work on the universe.
🌍 9. Aristotle (384–322 BC)
Field: Philosophy, Biology, Physics
Key Contributions:
Foundations of logic, ethics, and natural sciences
Early studies in zoology and classification
Why He’s Great:
Aristotle’s influence spans over 2,000 years. He laid the groundwork for virtually every branch of science and philosophy.
🧫 10. Rosalind Franklin (1920–1958)
Field: Chemistry, Molecular Biology
Key Contributions:
X-ray diffraction images of DNA (Photo 51)
Contributed to discovery of DNA’s double-helix structure
Why She’s Great:
Though overlooked in her time, Franklin’s work was critical in unlocking the structure of life itself — DNA.
