Thomas Henry Huxley was an English biologist and anthropologist. He specialized in comparative anatomy and was a proponent of Charles Darwin's theory of evolution. Despite having little formal schooling, he went on to become one of the finest comparative anatomists of the 19th century. He was the chair of natural history at the Royal School of Mines for 31 years.
Edward Jenner was an English scientist and physician. Referred to as the father of immunology, Jenner is credited with pioneering the concept of vaccines.

In 2002, Jenner was included in BBC’s Greatest Britons list.

Jeremy Wade is a British TV presenter, biologist, and freshwater detective. He is best known for his TV series River Monsters, Mighty Rivers, and Dark Waters. He attended the University of Kent and began his career as a biology teacher. He made his TV debut by chance and didn’t take long to become a popular TV presenter.
Herbert Spencer was the man behind the expression “survival of the fittest,” after reading Charles Darwin's iconic work On the Origin of Species. The British anthropologist, sociologist, and philosopher introduced the concept of Social Darwinism, which applied the theory of evolution to societies and social classes.
British geneticist J.B.S. Haldane is remembered for his pioneering use of statistics in biology. A proponent of neo-Darwinism, he was the son of physiologist John Scott Haldane and had begun assisting his father at age 8. He later joined the British Communist Party and also moved to India.
Ronald Fisher was a British polymath, statistician, geneticist, mathematician, and academic. He is credited to have single-handedly created the foundations for modern statistical science. He made important contributions to the field of genetics and is known as one of the three principal founders of population genetics. He was elected to the Royal Society in 1929.

Dorothy Hodgkin received the 1964 Nobel Prize for mapping the structure of penicillin and Vitamin B12. She is also known for her work on insulin. Beginning her work on structure of an organic compound by using X-ray crystallography as an undergraduate student, she later developed it further and used it to determine the three-dimensional structure of complex organic molecules.



Renowned James Lovelock is best known for propagating the Gaia hypothesis, which states that every living being on planet Earth is part of a single self-regulating superorganism. He is also known for his long association with NIMR, London, and Harvard University and has over 50 patents under his name.



One of the most influential evolutionary biologists of his generation, John Maynard Smith was originally aeronautical engineer. Later, he took a second degree in genetics and did extensive research on subjects like population genetics and evolution of sex. Known for formalizing the central concept in evolutionary game theory, he introduced the evolutionarily stable strategy, impacting a wide variety of studies.

Geneticist Anne McLaren is remembered for her pioneering research in embryology that paved the way for further research in fertility treatments such as in-vitro fertilization. The Royal Society fellow had also appeared as a child actor in the film adaptation of the H.G. Wells novel Things to Come.


Born to an ENT surgeon in Germany, Hans Adolf Krebs followed in his father’s footsteps and studied medicine. After fleeing Nazi Germany, he went to England, where he joined the University of Cambridge as a researcher. The Nobel Prize-winning scientist is remembered for his groundbreaking discovery of cellular respiration.




British biologist Ian Wilmut revolutionized embryology by leading the team of researchers who successfully created the first cloned mammal, the sheep named Dolly. A leading proponent of cryopreservation, he also implanted the first calf embryo, Frostie, in a surrogate cow. He was later knighted for his achievements.





Apart from being a successful scientist with a focus on neurodegenerative diseases such as Parkinson's disease and Alzheimer's disease, Susan Greenfield teaches pharmacology at the Lincoln College, Oxford. She is also part of the House of Lords and has penned a sci-fi novel. She supports causes such as Dignity in Dying, too.

Charles Galton Darwin was an English physicist. Born into a prominent family of intellectuals, he was the son of mathematician George Howard Darwin and a grandson of biologist Charles Darwin. He studied mathematics at Trinity College, Cambridge, and began an academic career. He, later on, served as the director of the National Physical Laboratory (NPL). He loved to travel.

British embryologist C.H. Waddington had studied paleontology before turning to biology. A professor of zoology and embryology, he later also taught animal genetics. His interests also included poetry, painting, and Marxism. He introduced concepts such as epigenetic landscape and genetic assimilation, and penned books such as Principles of Embryology.

Venkatraman Ramakrishnan is a British-American structural biologist whose research on the function of the ribosome earned him the 2009 Nobel Prize in Chemistry which he shared with Ada Yonath and Thomas A. Steitz. From 2015 to 2020, he served as the president of the Royal Society.




The son of a nurseryman, British botanist John Lindley revolutionized the plant classification system by introducing a method of considering all characters of plants. Known for his iconic work The Vegetable Kingdom, he also had a wide collection of orchids, which eventually found a place at the Kew Gardens.

Norman Heatley was an English biochemist and biologist. He was part of a team of Oxford University scientists whose work led to the development of penicillin. Heatley is credited with developing a technique for purifying penicillin in bulk. Norman Heatley's contribution in the development of penicillin was not fully recognized until 1990.



Apart from being a scientist and physician, John Boyd Orr also conducted ground-breaking research on nutrition. The Nobel Peace Prize winner, who was known for his campaigns to end world hunger, had also served the British army and navy as a medical officer. He was later knighted, too.
