1. Charles Darwin (1809 - 1882)

With an HPI of 93.29, Charles Darwin is the most famous British Biologist.  His biography has been translated into 185 different languages on wikipedia.

Charles Robert Darwin (; 12 February 1809 – 19 April 1882) was an English naturalist, geologist and biologist, best known for his contributions to the science of evolution. His proposition that all species of life have descended over time from common ancestors is now widely accepted, and considered a foundational concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history, and he was honoured by burial in Westminster Abbey.Darwin published his theory of evolution with compelling evidence in his 1859 book On the Origin of Species. By the 1870s, the scientific community and a majority of the educated public had accepted evolution as a fact. However, many favoured competing explanations which gave only a minor role to natural selection, and it was not until the emergence of the modern evolutionary synthesis from the 1930s to the 1950s that a broad consensus developed in which natural selection was the basic mechanism of evolution. Darwin's scientific discovery is the unifying theory of the life sciences, explaining the diversity of life.Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. Studies at the University of Cambridge (Christ's College) encouraged his passion for natural science. His five-year voyage on HMS Beagle established him as an eminent geologist whose observations and theories supported Charles Lyell's conception of gradual geological change, and publication of his journal of the voyage made him famous as a popular author.Puzzled by the geographical distribution of wildlife and fossils he collected on the voyage, Darwin began detailed investigations, and in 1838 conceived his theory of natural selection. Although he discussed his ideas with several naturalists, he needed time for extensive research and his geological work had priority. He was writing up his theory in 1858 when Alfred Russel Wallace sent him an essay that described the same idea, prompting immediate joint publication of both of their theories. Darwin's work established evolutionary descent with modification as the dominant scientific explanation of diversification in nature. In 1871 he examined human evolution and sexual selection in The Descent of Man, and Selection in Relation to Sex, followed by The Expression of the Emotions in Man and Animals (1872). His research on plants was published in a series of books, and in his final book, The Formation of Vegetable Mould, through the Actions of Worms (1881), he examined earthworms and their effect on soil.

2. Alexander Fleming (1881 - 1955)

With an HPI of 86.31, Alexander Fleming is the 2nd most famous British Biologist.  His biography has been translated into 102 different languages.

Sir Alexander Fleming (6 August 1881 – 11 March 1955) was a Scottish physician and microbiologist, best known for discovering the enzyme lysozyme and the world's first broadly effective antibiotic substance which he named penicillin. He discovered lysozyme from his nasal discharge in 1922, and along with it a bacterium he named Micrococcus Lysodeikticus, later renamed Micrococcus luteus. His discovery of what is later named benzylpenicillin (or penicillin G) from the mould Penicillium rubens in 1928, is described as the "single greatest victory ever achieved over disease." For this discovery he shared the Nobel Prize in Physiology or Medicine in 1945 with Howard Florey and Ernst Boris Chain.Fleming was knighted for his scientific achievements in 1944. In 1999, he was named in Time magazine's list of the 100 Most Important People of the 20th century. In 2002, he was chosen in the BBC's television poll for determining the 100 Greatest Britons, and in 2009, he was also voted third "greatest Scot" in an opinion poll conducted by STV, behind only Robert Burns and William Wallace.

3. Alfred Russel Wallace (1823 - 1913)

With an HPI of 79.30, Alfred Russel Wallace is the 3rd most famous British Biologist.  His biography has been translated into 73 different languages.

Alfred Russel Wallace (8 January 1823 – 7 November 1913) was a British naturalist, explorer, geographer, anthropologist, biologist and illustrator. He is best known for independently conceiving the theory of evolution through natural selection; his paper on the subject was jointly published with some of Charles Darwin's writings in 1858. This prompted Darwin to publish On the Origin of Species. Like Darwin, Wallace did extensive fieldwork; first in the Amazon River basin, and then in the Malay Archipelago, where he identified the faunal divide now termed the Wallace Line, which separates the Indonesian archipelago into two distinct parts: a western portion in which the animals are largely of Asian origin, and an eastern portion where the fauna reflect Australasia. He was considered the 19th century's leading expert on the geographical distribution of animal species and is sometimes called the "father of biogeography". Wallace was one of the leading evolutionary thinkers of the 19th century and made many other contributions to the development of evolutionary theory besides being co-discoverer of natural selection. These included the concepts of warning colouration in animals, and reinforcement (sometimes known as the Wallace effect), a hypothesis on how natural selection could contribute to speciation by encouraging the development of barriers against hybridisation. Wallace's 1904 book Man's Place in the Universe was the first serious attempt by a biologist to evaluate the likelihood of life on other planets. He was also one of the first scientists to write a serious exploration of the subject of whether there was life on Mars.Wallace was strongly attracted to unconventional ideas (such as evolution). His advocacy of spiritualism and his belief in a non-material origin for the higher mental faculties of humans strained his relationship with some members of the scientific establishment. Aside from scientific work, he was a social activist who was critical of what he considered to be an unjust social and economic system (capitalism) in 19th-century Britain. His interest in natural history resulted in his being one of the first prominent scientists to raise concerns over the environmental impact of human activity. He was also a prolific author who wrote on both scientific and social issues; his account of his adventures and observations during his explorations in Singapore, Indonesia and Malaysia, The Malay Archipelago, was both popular and highly regarded. Since its publication in 1869, it has never been out of print. Wallace had financial difficulties throughout much of his life. His Amazon and Far Eastern trips were supported by the sale of specimens he collected and, after he lost most of the considerable money he made from those sales in unsuccessful investments, he had to support himself mostly from the publications he produced. Unlike some of his contemporaries in the British scientific community, such as Darwin and Charles Lyell, he had no family wealth to fall back on, and he was unsuccessful in finding a long-term salaried position, receiving no regular income until he was awarded a small government pension, through Darwin's efforts, in 1881.

4. Rosalind Franklin (1920 - 1958)

With an HPI of 78.69, Rosalind Franklin is the 4th most famous British Biologist.  Her biography has been translated into 79 different languages.

Rosalind Elsie Franklin (25 July 1920 – 16 April 1958) was an English chemist and X-ray crystallographer whose work was central to the understanding of the molecular structures of DNA (deoxyribonucleic acid), RNA (ribonucleic acid), viruses, coal, and graphite. Although her works on coal and viruses were appreciated in her lifetime, her contributions to the discovery of the structure of DNA were largely recognised posthumously. Franklin was educated at Norland Place, a private day school in West London, Lindores School for Young Ladies, a boarding school in Sussex, and St Paul's Girls' School, London. Then she studied the Natural Sciences Tripos at Newnham College, Cambridge, from which she graduated in 1941. Earning a research fellowship, she joined the University of Cambridge physical chemistry laboratory under Ronald George Wreyford Norrish, who disappointed her for his lack of enthusiasm. The British Coal Utilisation Research Association (BCURA) offered her a research position in 1942 and started her work on coals. This helped her earn a Ph.D. in 1945. She went to Paris in 1947 as a chercheur (postdoctoral researcher) under Jacques Mering at the Laboratoire Central des Services Chimiques de l'Etat, where she became an accomplished X-ray crystallographer. She became a research associate at King's College London in 1951 and worked on X-ray diffraction studies, which would eventually facilitate the discovery of the double helix structure of DNA. In 1953, after two years, owing to disagreement with her director John Randall and more so with her colleague Maurice Wilkins, she was compelled to move to Birkbeck College. At Birkbeck, John Desmond Bernal, chair of the physics department, offered her a separate research team. She died in 1958 at age 37 of ovarian cancer. Franklin is best known for her work on the X-ray diffraction images of DNA, particularly Photo 51, while at King's College London, which led to the discovery of the DNA double helix for which Francis Crick, James Watson, and Maurice Wilkins shared the Nobel Prize in Physiology or Medicine in 1962. Watson suggested that Franklin would have ideally been awarded a Nobel Prize in Chemistry, along with Wilkins but, although there was not yet a rule against posthumous awards, the Nobel Committee generally did not make posthumous nominations.After finishing her work on DNA, Franklin led pioneering work at Birkbeck on the molecular structures of viruses. Her team member Aaron Klug continued her research, winning the Nobel Prize in Chemistry in 1982.

5. Francis Crick (1916 - 2004)

With an HPI of 78.54, Francis Crick is the 5th most famous British Biologist.  His biography has been translated into 84 different languages.

Francis Harry Compton Crick (8 June 1916 – 28 July 2004) was a British molecular biologist, biophysicist, and neuroscientist. In 1953, he co-authored with James Watson the academic paper proposing the double helix structure of the DNA molecule. Together with Watson and Maurice Wilkins, he was jointly awarded the 1962 Nobel Prize in Physiology or Medicine "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material".Crick was an important theoretical molecular biologist and played a crucial role in research related to revealing the helical structure of DNA. He is widely known for the use of the term "central dogma" to summarise the idea that once information is transferred from nucleic acids (DNA or RNA) to proteins, it cannot flow back to nucleic acids. In other words, the final step in the flow of information from nucleic acids to proteins is irreversible.During the remainder of his career, he held the post of J.W. Kieckhefer Distinguished Research Professor at the Salk Institute for Biological Studies in La Jolla, California. His later research centered on theoretical neurobiology and attempts to advance the scientific study of human consciousness. He remained in this post until his death; "he was editing a manuscript on his death bed, a scientist until the bitter end" according to Christof Koch.

6. Thomas Henry Huxley (1825 - 1895)

With an HPI of 78.23, Thomas Henry Huxley is the 6th most famous British Biologist.  His biography has been translated into 69 different languages.

Thomas Henry Huxley (4 May 1825 – 29 June 1895) was an English biologist and anthropologist specialising in comparative anatomy. He is known as "Darwin's Bulldog" for his advocacy of Charles Darwin's theory of evolution.The stories regarding Huxley's famous debate in 1860 with Samuel Wilberforce were a key moment in the wider acceptance of evolution and in his own career, although historians think that the surviving story of the debate is a later fabrication. Huxley had been planning to leave Oxford on the previous day, but, after an encounter with Robert Chambers, the author of Vestiges, he changed his mind and decided to join the debate. Wilberforce was coached by Richard Owen, against whom Huxley also debated about whether humans were closely related to apes. Huxley was slow to accept some of Darwin's ideas, such as gradualism, and was undecided about natural selection, but despite this he was wholehearted in his public support of Darwin. Instrumental in developing scientific education in Britain, he fought against the more extreme versions of religious tradition. Originally coining the term in 1869, Huxley elaborated on "agnosticism" in 1889 to frame the nature of claims in terms of what is knowable and what is not. Huxley statesAgnosticism, in fact, is not a creed, but a method, the essence of which lies in the rigorous application of a single principle... the fundamental axiom of modern science... In matters of the intellect, follow your reason as far as it will take you, without regard to any other consideration... In matters of the intellect, do not pretend that conclusions are certain which are not demonstrated or demonstrable. Use of that term has continued to the present day (see Thomas Henry Huxley and agnosticism). Much of Huxley's agnosticism is influenced by Kantian views on human perception and the ability to rely on rational evidence rather than belief systems.Huxley had little formal schooling and was virtually self-taught. He became perhaps the finest comparative anatomist of the later 19th century. He worked on invertebrates, clarifying relationships between groups previously little understood. Later, he worked on vertebrates, especially on the relationship between apes and humans. After comparing Archaeopteryx with Compsognathus, he concluded that birds evolved from small carnivorous dinosaurs, a theory widely accepted today. The tendency has been for this fine anatomical work to be overshadowed by his energetic and controversial activity in favour of evolution, and by his extensive public work on scientific education, both of which had significant effects on society in Britain and elsewhere. Huxley's 1893 Romanes Lecture, “Evolution and Ethics” is exceedingly influential in China; the Chinese translation of Huxley's lecture even transformed the Chinese translation of Darwin's Origin of Species.

7. Richard Owen (1804 - 1892)

With an HPI of 74.29, Richard Owen is the 7th most famous British Biologist.  His biography has been translated into 54 different languages.

Sir Richard Owen (20 July 1804 – 18 December 1892) was an English biologist, comparative anatomist and paleontologist. Despite being a controversial figure, Owen is generally considered to have been an outstanding naturalist with a remarkable gift for interpreting fossils. Owen produced a vast array of scientific work, but is probably best remembered today for coining the word Dinosauria (meaning "Terrible Reptile" or "Fearfully Great Reptile"). An outspoken critic of Charles Darwin's theory of evolution by natural selection, Owen agreed with Darwin that evolution occurred, but thought it was more complex than outlined in Darwin's On the Origin of Species. Owen's approach to evolution can be seen as having anticipated the issues that have gained greater attention with the recent emergence of evolutionary developmental biology.Owen was the first president of the Microscopical Society of London in 1839 and edited many issues of its journal – then known as The Microscopic Journal.Owen also campaigned for the natural specimens in the British Museum to be given a new home. This resulted in the establishment, in 1881, of the now world-famous Natural History Museum in South Kensington, London. Bill Bryson argues that, "by making the Natural History Museum an institution for everyone, Owen transformed our expectations of what museums are for".While he made several contributions to science and public learning, Owen was a controversial figure among his contemporaries, such as Thomas Henry Huxley. His later career was tainted by controversies, many of which involved accusations that he took credit for other people's work.

8. Erasmus Darwin (1731 - 1802)

With an HPI of 73.48, Erasmus Darwin is the 8th most famous British Biologist.  His biography has been translated into 42 different languages.

Erasmus Darwin (12 December 1731 – 18 April 1802) was an English physician. One of the key thinkers of the Midlands Enlightenment, he was also a natural philosopher, physiologist, slave-trade abolitionist, inventor and poet. His poems included much natural history, including a statement of evolution and the relatedness of all forms of life. He was a member of the Darwin–Wedgwood family, which includes his grandsons Charles Darwin and Francis Galton. Darwin was a founding member of the Lunar Society of Birmingham, a discussion group of pioneering industrialists and natural philosophers. He turned down an invitation of George III's to become a physician to the King.

9. Robert Brown (1773 - 1858)

With an HPI of 73.42, Robert Brown is the 9th most famous British Biologist.  His biography has been translated into 53 different languages.

Robert Brown FRSE FRS FLS MWS (21 December 1773 – 10 June 1858) was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders.

10. Christian de Duve (1917 - 2013)

With an HPI of 73.26, Christian de Duve is the 10th most famous British Biologist.  His biography has been translated into 55 different languages.

Christian René Marie Joseph, Viscount de Duve (2 October 1917 – 4 May 2013) was a Nobel Prize-winning English-born Belgian cytologist and biochemist. He made serendipitous discoveries of two cell organelles, peroxisome and lysosome, for which he shared the Nobel Prize in Physiology or Medicine in 1974 with Albert Claude and George E. Palade ("for their discoveries concerning the structural and functional organization of the cell"). In addition to peroxisome and lysosome, he invented the scientific names such as autophagy, endocytosis, and exocytosis in a single occasion.The son of Belgian refugees during the First World War, de Duve was born in Thames Ditton, Surrey, England.His family returned to Belgium in 1920. He was educated by the Jesuits at Onze-Lieve-Vrouwinstituut in Antwerp, and studied medicine at the Catholic University of Leuven. Upon earning his MD in 1941, he joined research in chemistry, working on insulin and its role in diabetes mellitus. His thesis earned him the highest university degree agrégation de l'enseignement supérieur (equivalent to PhD) in 1945.With his work on the purification of penicillin, he obtained an MSc degree in 1946. He went for further training under (later Nobel Prize winners) Hugo Theorell at the Karolinska Institutet in Stockholm, and Carl and Gerti Cori at the Washington University in St. Louis. He joined the faculty of medicine at Leuven in 1947. In 1960 he was invited to the Rockfeller Institute (now Rockefeller University). With mutual arrangement with Leuven, he became professor in both universities from 1962, dividing his time between Leuven and New York. He became emeritus professor of the University of Louvain in 1985, and of Rockefeller in 1988.De Duve was granted the rank of Viscount in 1989 by King Baudouin of Belgium. He was also a recipient of Francqui Prize, Gairdner Foundation International Award, Heineken Prize, and E. B. Wilson Medal. In 1974 he founded the International Institute of Cellular and Molecular Pathology in Brussels, eventually renamed the de Duve Institute in 2005. He was the founding President of the L'Oréal-UNESCO Awards for Women in Science.
