We’re all familiar with the Einsteins and Hawkings of history, but there are many who have influenced the direction and development of science. Here are seven scientists and philosophers who have shaped how science is practiced today.


Tim Berners-Lee

Sir Timothy Berners-Lee (1955-present) is an English computer scientist. Most notably, he is the inventor of the World Wide Web and the first web browser. If not for his innovative insight and altruistic intent (he gave away the idea for free!), the way you’re viewing this very page may have been completely different. These days, Berners-Lee is fighting to save his vision. The Web has transformed, he says, and is being abused in ways he always feared – from political interference to social control. The only way forward is pushing for ethical design and pushing back against web monopolisation.

Legacy: The World Wide Web as we know it.


Jane Goodall

Dame Jane Goodall (1934-present) is an English primatologist and anthropologistOver 60 years ago, Goodall entered the forest of Gombe Stream National Park and made the ground-breaking discovery that chimpanzees make and use tools and exhibit other human-like behaviour, including armed conflict. Since then, she has spent decades continuing her extensive and hands-on research with chimpanzees, written a plethora of books, founded the Jane Goodall Institute to scale up conservation efforts, and is forever changing the way humans relate to animals.

Legacy: “Only if we understand, will we care. Only if we care, will we help. Only if we help, shall all be saved.”


Karl Popper

Sir Karl Popper (1902-1994) was an Austrian-British philosopher, academic and social commentator. He is best known as one of the greatest philosophers of science in the twentieth century, having contributed a new and novel way of thinking about the methodology of science. Against the prevailing empiricist idea that rationally acceptable beliefs can only be justified through direct experience, Popper proposed the opposite. In fact, Popper argued, theories can never be proven to be true. The best we can do as humans is ensure that they are able to be false and continue testing them for exceptions, even as we use these assumptions to further our knowledge. One of Popper’s most enduring thoughts is that we should rationally prefer the simplest theory that explains the relevant facts.

Legacy: The idea that to be scientific is to be fallible.


Marie Curie

Marie Curie (1867-1934) was a Polish-French physicist and chemist. She was a pioneer of radioactivity research, coining the term with her husband, and discovered and named the new elements “polonium” and “radium”. During the course of her extensive career, she was the first woman to be awarded a Nobel Prize, and the first to be awarded two Nobel Prizes in two scientific fields: physics and chemistry. Due to the underfunded research conditions of time and ignorance about the danger of radiation exposure, it’s thought that a large factor in her death was radiation sickness.

Legacy: Discovering polonium and radium, pioneering research into the use of radiation in medicine and fundamentally changing our understanding of radioactivity. 


René Descartes

René Descartes (1596-1650) was a French philosopher, mathematician and scientist. Descartes is most widely known for his philosophy – including the famous “I think, therefore I am” – but he was also an influential mathematician and scientistDescartes possibly most enduring legacy is something high school students are very familiar with today – coordinate geometry. Also known as analytic or Cartesian geometry, this is the use of algebra and a coordinates graph with x and y axes to find unknown measurements. Descartes was also interested in physics, and it is thought that he had great influence on the direction that a young Isaac Newton took with his research  Newton’s laws of motion were eventually modelled after Descartes’ three laws of motion, outlined in Principles of Philosophy. In his essay on optics, he independently discovered the law of reflection – the mathematical explanation of the angle at which light waves are reflected.

Legacy: “The seeker after truth must, once in the course of his life, doubt everything, as far as is possible.”


Rosalind Franklin

Rosalind Franklin (1920-1958) was an English chemist and X-ray crystallographer who is most famous for her posthumous recognition. During her life, including in her PhD thesis, she researched the properties and utility of coal, and the structure of various viruses. She is now often referred to as “the forgotten heroine” for the lack of recognition she received for her contributions to the discovery of the structure of DNA. Even one of the recipients of the Nobel Prize for the discovery of the DNA double helix suggested that Franklin should have been among the recipients, but posthumous nominations were very rare. Unfortunately, this was not her only posthumous brush with a Nobel Prize, either. One day before she and her team member were to unveil the structure of a new virus affecting tobacco farms, Franklin died of ovarian cancer. Over two decades later, her team member went on to win the Nobel Prize in Chemistry for the continued research on the virus. Since her death, she has been recognised with over 50 varying awards and honours.

Legacy: Foundational research that informed the discovery of the structure of DNA, coal and graphite.


Noam Chomsky 

Noam Chomsky (1928-present) is an American linguist, philosopher, cognitive scientist and social/political critic. While Chomsky may be better known as a political dissident and social critic, he also played a foundational role in the development of modern linguistics and founded a new field: cognitive science, the scientific study of the mind. Chomsky’s research and criticism of behaviourism saw the decline in behaviourist psychology, and his interdisciplinary work in linguistics and cognitive science has gone on to influence advancements in a variety of fields including computer science, immunology and music theory.

Legacy: Establishing cognitive science as a formal scientific field and inciting the fall of behaviourism.
