Here are 20 of the most prominent scientists from the fifteenth century to the present, along with an explanation of how their significant contributions to numerous scientific fields continue to influence us:

1. Nicolaus Copernicus

Famous Scientists
Astronomer and mathematician
1473-1543People mistakenly thought that Earth was the center of the universe for hundreds of years. Contrary to popular belief, Copernicus postulated that a planet’s orbital parameters were determined by its distance from the central sun.Copernicus’ theories, however, were controversial because they contradicting the teachings of the Roman Catholic Church, rather than being a breakthrough. The church even forbade him from collecting research altogether On the Revolutions of the Heavenly Spheres, in 1616 long after the German scientist’s death.

2. Galileo Galilei

Famous Scientists
Physicist and astronomer

1564-1642Through the use of early telescopes and improved design, Galileo literally altered our perception of the world. The scientist from Italy created lenses that could magnify objects twenty times.

Using his instruments, Galileo peered up at the sky and saw stars in the Milky Way that were too far away for the naked eye to see, as well as Jupiter’s four largest moons, which bear his name today. The basis of modern astronomy establishment is by his discoveries.

3. Robert Hooke

Famous Scientists
Astronomer, physicist, and biologist

Englishman Hooke coined  the word “cell,” which is currently used to refer to the fundamental structural component of all living things, in his 1665 book Micrographia after studying the cell walls in cork tissue slices. However, he studied more than just biology. His most well-known contribution is Hooke’s Law, which states that the force needed to compress or extend a spring depends on how far the spring is compressed or extended. In addition, he contributed to the reconstruction of London structures damaged in the “Great Fire” of 1666.

4. Sir Isaac Newton

Famous Scientists
Physicist and mathematician
1643-1727Newton’s three laws of motion, one of which states that unless an object is acted upon, it will remain at rest or in uniform motion, are probably familiar to you. But did you also know that the Englishman was able to determine the masses of all planets and the tides in the Earth’s oceans thanks to his theory of gravity? Newton continues to be one of the greatest minds in history, despite the fact that Albert Einstein would eventually refine some of his theories.Fun fact: When Newton was twelve years old, his mother attempted to get him to drop out of school so he could become a farmer. It appears fortunate that the plan did not work out.

5. Charles Darwin

Famous Scientists

Raised in a Christian household and adhering to creationism, Darwin was born and raised in Great Britain. It’s not what you would anticipate from the man who gave a thorough explanation of the theory of evolution in his seminal work On the Origins of Species by Means of Natural Selection, published in 1859. He expounded upon the idea of natural selection in his writings, according to which species that undergo evolution and adjust to their surroundings prosper whereas others face extinction.

6. Ada Lovelace

Famous Scientists
Mathematician and computer scientist
1815-1852An 1800s computer scientist? Yes, Lovelace’s annotations and guidance on her mentor Charles Babbage’s “analytical engine” are regarded as a turning point in the development of contemporary computers. For instance, Lovelace, who was born in London, was the first to theorize looping—a technique in which computer programs repeatedly execute a sequence of instructions until the intended result is obtained.Even though her contributions weren’t acknowledged until the 20th century, the U.S. Department of Defense named the new computer language Ada in her honor in 1980, permanently cementing her legacy.

7. Gregor Mendel

Famous Scientists

Rather than inheriting his father’s farm, Mendel, an Austrian, chose to become an Augustinian monk and a teacher. Mendel’s ability to grow paid off, as he studied the inheritance of traits from pea plants. Modern genetic research was founded on his discoveries that traits were either recessive or dominant and passed on independently of one another.

8. Louis Pasteur

Famous Scientists
Chemist and microbiologist
1822-1895Using his observations of microorganisms, Pasteur proposed hygienic practices that are commonplace in modern times, such as sterilizing surgical instruments, dressings, and linens. He also gives his name to the process of pasteurizing food, which involves heating it to kill bacteria.The French scientist’s work on developing vaccines against cholera, smallpox, anthrax, and rabies, however, is undoubtedly what has made him most famous. Notwithstanding a severe brain stroke he suffered in 1868, he worked on the rabies vaccine.

9. Sigmund Freud

Famous Scientists

Freud was born in what is now the Czech Republic but grew up in Austria. Although his research primarily concentrated on neurobiology, he became popular for his psychoanalytic theory that past traumatic experiences caused neuroses in patients. Additionally, he postulated that dreams were a way for people to deal with subconscious conflicts and that the id, ego, and superego are the three fundamental components of human personality.

10. Nikola Tesla

Famous Scientists
Physicist and mathematician
1856-1943Most likely, you are reading this in a well-lit space. If so, you can thank the Tesla who was born in Croatia. While rival Thomas Edison developed a direct current system, he designed the alternative current, or AC, electric system, which is still the most widely used form of electricity worldwide.Additionally, the foundation for wireless technology was laid by his patented Tesla coil, which is used in radio transmission antennas. The scientist also contributed to the development of radar and remote technology.

11. George Washington Carver

Famous Scientists
Botanist and agricultural scientist
Circa 1864-1943

The most popular contribution made by Washington Carver is to the peanut plant. The native of Missouri, who was born into slavery, came up with over 300 uses for it, including recipes for foods like bread and candies as well as shaving cream, shampoo, and plastics. However, he also protected farmers by imparting knowledge on cultivation and animal care. Washington Carver established productive relationships with influential people, such as Henry Ford, the automaker, with whom he collaborated to develop an experimental lightweight car body and a substitute for rubber derived from soybeans.

12. Marie Curie

 Famous Scientists

Physicist and chemist
1867-1934Originating in what is now Poland, Curie became the first person to win two Nobel Prizes and the first woman to win a Nobel Prize in physics.Together with her husband Pierre Curie, the scientist made the discoveries of radioactivity, radium, and polonium. She also supported the deployment of portable X-ray devices to the front lines of World War I. Curie most likely contracted aplastic anemia from radiation exposure, which led to her death.

13. Albert Einstein

 Famous Scientists

1879-1955Apart from his unruly hair and alleged dislike of socks, Einstein gained notoriety for his theory of relativity, which postulated the merging of space and time. Not to mention the well-known equation E=MC2, which demonstrated that even the smallest particles are capable of producing enormous amounts of energy.

The German scientist, who once referred to racism as a “disease,” was also an advocate for civil rights. In the 1940s, he became a member of the National Association for the Advancement of Colored People.

14. Niels Bohr

Famous Scientists
1885-1962Bohr attended the University of Copenhagen in Denmark, where he also played soccer, before moving to England to work with J.J. Thomson, the man who discovered the electron. Bohr put forth a completely different theory of the atom, one in which electrons are able to transition between different energies. This contributed to the development of quantum mechanics.Bohr also played a significant role in the Manhattan Project, which helped the US create an atomic bomb during World War II. Bohr collaborated with J. Robert Oppenheimer, the project director and subject of the 2023 biopic Oppenheimer.

15. Rachel Carson

 Famous Scientists

In 1962, Carson wrote her popular book Silent Spring. The current environmental movement is said to have started as a result of the American scientist’s studies on the harmful effects of DDT and other pesticides in the environment. The Environmental Protection Agency was founded in 1970, shortly after the book’s publication, and DDT use was outlawed in 1972. In 1980, Carson—who passed away from breast cancer—was awarded the Presidential Medal of Freedom posthumously.

16. Alan Turing

 Famous Scientists
Computer scientist and mathematician
1912-1954During World War II, Turing, a proficient cryptanalyst, assisted in decoding coded communications from the German military. The British mathematician, whose Turing Test is said to gauge a machine’s capacity to display behaviors akin to those of a human, is also regarded as the founder of computer science and artificial intelligence.The life and work of Alan Turing during the war served as the inspiration for Benedict Cumberbatch’s 2014 film The Imitation Game.

17. Gertrude B. Elion

 Famous Scientists
Biochemist and pharmacologist
Throughout her extraordinary career, Elion—who was awarded the 1988 Nobel Prize in Physiology or Medicine—developed forty-five medical patents. After being employed by Burroughs-Wellcome (now known as GlaxoSmithKline) in 1944, the American quickly developed the medication 6-MP to treat leukemia. She and her colleagues disproved the notion that a medication that could eradicate a virus would be too harmful for people when they developed the antiviral medication acyclovir in 1977. It treats shingles, chickenpox, and herpes.

18. Katherine Johnson

 Famous Scientists
1918-2020Johnson made possible every early NASA achievement, including the first-ever space flight by astronaut Alan Shepard in 1961 and the moon landing by Neil Armstrong and the Apollo 11 crew eight years later. The native of West Virginia contributed to the mathematical computations required to ascertain their accurate flight paths.In 2017, NASA honored Johnson with a building at its Langley Research Center in Virginia. Taraji P. Henson portrayed her in the 2016 film Hidden Figures, which told her inspirational true story.

19. Rosalind Franklin

Famous Scientists
Chemist and biophysicist

Human DNA exists in two forms: a wet “B” form and a dry “A” form. Franklin discovered this using X-ray diffraction techniques while he was employed at King’s College London in 1951. Franklin’s discovery was disregarded, though, as a result of a colleague giving James Watson and Francis Crick access to her data. The double helix model of DNA structure was subsequently developed by that duo. At age 37, Franklin passed away from ovarian cancer.

20. Jane Goodall

Famous Scientists

We can now better appreciate the similarities between humans and our evolutionary ancestors thanks to Goodall’s extensive research on chimpanzees. The British scientist found that chimps are not exclusively vegetarian as previously thought, that they develop sophisticated language and social structures, and that they make and use tools after arriving in Tanzania in 1960.

After gaining an understanding of chimpanzees, Goodall focused her efforts on protecting their natural habitats and stopping the inhumane treatment of the animals in research studies.
