10 Greatest Scientists of All Time and Their Groundbreaking Contributions

January 2, 2025 | 02:32 pm

TEMPO.CO, Jakarta - Science has always been the driving force behind human progress. This field of study has also undergone significant development and evolution over time, largely attributable to the groundbreaking contributions of revolutionary thinkers.

Citing Discover Magazine, Biography, and several other sources, let’s take a closer look at some of the greatest scientists of all time, who left an indelible mark on history. Keep reading to find the complete list.

1. Albert Einstein

Albert Einstein is widely regarded as one of the greatest scientists of all time, whose contributions have profoundly influenced the world of science and innovation. His famous equation, E=MC2, remains relevant in comprehending the capacity of particles to generate energy that exceeds their own size.

Nevertheless, the physicist is particularly reputable for his revolutionary theory of relativity, suggesting that space and time are intertwined. Beyond his groundbreaking work, the German physicist was a passionate advocate for civil rights.

2. Isaac Newton

Who would have thought that an apple falling on the head of Isaac Newton would greatly contribute to his eventual recognition as one of the most significant figures in the history of science? Born on Christmas Day in 1642, Newton laid the foundation for classical mechanics, introducing laws of motion and universal gravitation.

National Geographic also notes that his works encompass optics and mathematics, notably calculus, further cementing his legacy as an influential scientist.

3. Charles Darwin

Despite the fact that his thoughts are considered to be in conflict with religious concepts, the father of evolution, Charles Darwin, forever changed biology with his theory of natural selection. His observations during the voyage of the HMS Beagle led to the revolutionary idea that species evolve over time.

4. Marie Curie

Marie Curie was reputable for being the first woman to receive a Nobel Prize—and the only person to win in two different sciences. Moreover, she should take all the credit for her relentless dedication to researching radioactivity, which paved the way for advancements in medical treatments and nuclear energy, even though it came at the cost of her own life.

She died of aplastic pernicious anemia, resulting from her constant exposure to radiation, in 1934. Regardless, Curie’s relentlessness in science continues to inspire generations of women in STEM.

5. Galileo Galilei

A prominent figure in astronomy, Galileo Galilei marked his name in the realm of science through his discovery of Jupiter’s four largest moons and the sources of the Milky Way’s faint glow, which comes from countless distant stars, following his improvements to the early telescopes. 

Regardless of his groundbreaking findings, Galileo was once in conflict with the Roman Catholic Church for his firm stance towards the Copernican model of the solar system, suggesting that the “motionless” Sun is the center of the universe. This resulted in his house arrest in 1633, which was not lifted until his death nine years later.

6. Pythagoras

Pythagoras was more than his Pythagorean theorem. The Greek mathematician was also a philosopher who believed numbers held the key to understanding the universe. His belief would be instrumental in shaping the foundations of geometry and mathematics.

7. Nikola Tesla

Nikola Tesla was a visionary inventor whose work in electrical engineering changed the modern world. His innovations span from alternating current (AC) systems to wireless communication, such as remote and radar technology.

8. Carl Linnaeus

Carl Linnaeus’ work is still visible today, notably in the field of biology. The Swedish biologist was the first to come up with a universal system of naming, ranking, and classifying plants and animals, Science notes.

His binomial system of nomenclature has considerably simplified the process of scientific communication. In recognition of his contributions, Linnaeus has often been named the "Father of Taxonomy."

9. Rosalind Franklin

Rosalind Franklin’s X-ray diffraction images were crucial to understanding DNA’s double-helix structure. Despite her remarkable contributions, she was overlooked during her lifetime, with much credit going to her colleagues, Francis Crick and James Watson.

10. Ada Lovelace

The modern realm of programming and computer science witnesses a notable predominance of male representations. This may come as a surprise to some, but the world’s first computer programmer was, in fact, a woman—and she was the one-and-only Ada Lovelace.

Developing interests in mathematics and computing since the age of 17, the London-born computer scientist’s breakthrough contributions include her work on Charles Babbage’s analytical engine. Lovelace was also the first to theorize the now-called loop in computer programming.
