* Peter Atkins (1940–): English chemist, Professor of chemistry at Lincoln College, Oxford in England.When asked by Rod Liddle in the documentary The Trouble with Atheism "Give me your views on the existence, or otherwise, of God", Peter Atkins replied "Well it's fairly straightforward: there isn't one. And there's no evidence for one, no reason to believe that there is one, and so I don't believe that there is one. And I think that it is rather foolish that people do think that there is one."
* Julius Axelrod (1912–2004): American Nobel Prize winning biochemist, noted for his work on the release and reuptake of catecholamine neurotransmitters and major contributions to the understanding of the pineal gland and how it is regulated during the sleep-wake cycle."Although he became an atheist early in life and resented the strict upbringing of his parents’ religion, he identified with Jewish culture and joined several international fights against anti-Semitism." Craver, Carl F: "Axelrod, Julius", Complete Dictionary of Scientific Biography Vol. 19 p. 122. Detroit: Charles Scribner's Sons, 2008.
* Sir Edward Battersby Bailey FRS (1881–1965): British geologist, director of the British Geological Survey."In religious matters he was an atheist." A.G. MacGregor: "Bailey, Edward Battersby", Complete Dictionary of Scientific Biography Vol. 1 p. 393. Detroit: Charles Scribner's Sons, 2008.
* Sir Patrick Bateson FRS (1938–): English biologist and science writer, Emeritus Professor of ethology at Cambridge University and president of the Zoological Society of London."A confirmed agnostic, he [Bateson] was converted to atheism after attending a dinner where he tried to converse with a woman who was a creationist. "For many years what had been good enough for Darwin was good enough for me. Not long after that dreadful dinner, Richard Dawkins wrote to me to ask whether I would publicly affirm my atheism. I could see no reason why not." " Lewis Smith, 'Science has second thoughts about life', The Times (London), January 1, 2008, Pg. 24.
* William Bateson (1861–1926): British geneticist, a Fellow of St. John's College, Cambridge, where he eventually became Master. He was the first person to use the term genetics to describe the study of heredity and biological inheritance, and the chief populariser of the ideas of Gregor Mendel following their rediscovery."William Bateson was a very militant atheist and a very bitter man, I fancy. Knowing that I was interested in biology, they invited me when I was still a school girl to go down and see the experimental garden. I remarked to him what I thought then, and still think, that doing research must be the most wonderful thing in the world and he snapped at me that it wasn’t wonderful at all, it was tedious, disheartening, annoying and anyhow you didn’t need an experimental garden to do research." Interview with Dr. Cecilia Gaposchkin by Owen Gingerich, March 5, 1968.
* Patrick Blackett OM, CH, FRS (1897–1974): Nobel Prize winning English experimental physicist known for his work on cloud chambers, cosmic rays, and paleomagnetism."The grandson of a vicar on his father’s side, Blackett respected religious observances that were established social customs, but described himself as agnostic or atheist."

* Susan Blackmore (1951–): English psychologist and memeticist, best known for her book The Meme Machine.In a Point of Inquiry podcast interview, Blackmore described religion as a collection of "really pernicious memes", "I think religious memeplexes are really amongst the nastiest viruses we have on the planet". Blackmore also practices Zen Buddhist meditation; later, when she was asked: "And you find this practice of Zen, the meditative practice, completely compatible with your lack of theism, your atheism...?" she replied: "Oh yes, I mean, there is no god in Buddhism...". Susan Blackmore - In Search of the Light, Point of Inquiry, December 15, 2006 (accessed April 1, 2008).
* Sir Hermann Bondi KCB, FRS (1919–2005): Anglo-Austrian mathematician and cosmologist, best known for co-developing the steady-state theory of the universe and important contributions to the theory of general relativity."Since his childhood in Vienna Bondi had been an atheist, developing from an early age a view on religion that associated it with repression and intolerance. This view, which he shared with Hoyle, never left him. On several occasions he spoke out on behalf of freethinking, so-called, and became early on active in British atheist or "humanist" circles. From 1982 to 1999, he was president of the British Humanist Association, and he also served as president of the Rationalist Press Association of United Kingdom." Helge Kragh: "Bondi, Hermann", Complete Dictionary of Scientific Biography Vol. 19 p. 343. Detroit: Charles Scribner's Sons, 2008. Accessed via Gale Virtual Reference Library April 29, 2008.In a letter to the Guardian, Jane Wynne Willson, Vice-President of the British Humanist Association, added to his obituary: "Also president of the Rationalist Press Association from 1982 until his death, and with a particular interest in Indian rationalism, Hermann was a strong supporter of the Atheist Centre in Andra Pradesh. He and his wife Christine visited the centre a number of times, and the hall in the science museum there bears his name. When presented with a prestigious international award, he divided a large sum of money between the Atheist Centre and women's health projects in Mumbai."

* Frank Close OBE (1945–): British particle physicist, Professor of Physics at the University of Oxford and a Fellow of Exeter College, Oxford, known for his lectures and writings making science intelligible to a wider audience, for which he was awarded the Institute of Physics's Kelvin Medal and Prize.When describing a total solar eclipse, Close wrote: "It was simultaneously ghastly, beautiful, supernatural. Even for a 21st century atheist, the vision was such that I thought, "If there is a heaven, this is what its entrance is like." The heavenly vision demanded music by Mozart; instead we had the crickets." Frank Close, 'Dark side of the moon', The Guardian, August 9, 2001, Guardian Online Pages, Pg. 8.
* Jerry Coyne (1949–): American professor of biology, known for his books on evolution and commentary on the intelligent design debate."Yet they [the NCSE] can afford to ignore us because, in the end, where else can we atheists go for support against creationists? [...] Am I grousing because, as an atheist and a non-accommodationist, my views are simply ignored by the NAS and NCSE? Not at all. I don't want these organizations to espouse or include my viewpoint. I want religion and atheism left completely out of all the official discourse of scientific societies and organizations that promote evolution."

* Sir Howard Dalton FRS (1944–2008): British microbiologist, Chief Scientific Advisor to the UK's Department for Environment, Food and Rural Affairs from March 2002 to September 2007."She advised him that he risked being called up, and suggested an unusual way to avoid the draft - by becoming a priest, one of the categories exempt from military service. Dalton discovered a little-known religious group called the Universal Life Church of California which for $25 would "ordain" anyone. He duly sent off a cheque and within days was delighted to learn that he was now a bona fide Minister of Religion. It became a running joke and his friends frequently addressed letters to the Reverend Howard Dalton; as a life-long atheist, he particularly relished the irony of his new title."

* Richard Dawkins (1941–): British zoologist, biologist, creator of the concepts of the selfish gene and the meme; outspoken atheist and popularizer of science, author of The God Delusion and founder of the Richard Dawkins Foundation for Reason and Science.Dawkins identifies himself as an atheist in his article "A Challenge to Atheists: Come Out of the Closet," Free Inquiry, Summer 2002. Excerpt reprinted at Positiveatheism.org
* Arnaud Denjoy (1884–1974): French mathematician, noted for his contributions to harmonic analysis and differential equations."Denjoy was an atheist, but tolerant of others' religious views; he was very interested in philosophical, psychological, and social issues." "Denjoy, Arnaud", Complete Dictionary of Scientific Biography Vol. 17, p.219. Detroit: Charles Scribner's Sons, 2008.
* Paul Dirac (1902–1984): British theoretical physicist, one of the founders of quantum mechanics, predicted the existence of antimatter, and won the Nobel Prize in Physics in 1933.Werner Heisenberg recollects a friendly conversation among young participants at the 1927 Solvay Conference about Einstein's and Planck's views on religion. Wolfgang Pauli, Heisenberg and Dirac took part in it. Among other things, Dirac said: "I cannot understand why we idle discussing religion. If we are honest — and as scientists honesty is our precise duty — we cannot help but admit that any religion is a pack of false statements, deprived of any real foundation. The very idea of God is a product of human imagination.[...] I do not recognize any religious myth, at least because they contradict one another.[...]" Pauli jokingly said: "Well, I'd say that also our friend Dirac has got a religion and the first commandment of this religion is: God does not exist and Paul Dirac is his prophet." "... I [Pauling] am not, however, militant in my atheism. The great English theoretical physicist Paul Dirac is a militant atheist. I suppose he is interested in arguing about the existence of God. I am not. It was once quipped that there is no God and Dirac is his prophet." 
* Albert Ellis (1913–2007): American psychologist who in 1955 developed Rational Emotive Behavior Therapy.Nielsen, Stevan Lars & Ellis, Albert. (1994). "A discussion with Albert Ellis: Reason, emotion and religion", Journal of Psychology and Christianity, 13(4), Win 1994. pp. 327-341. 
* Sandra Faber (1944–): American University Professor of Astronomy and Astrophysics at the University of California, Santa Cruz, also working at the Lick Observatory, who headed the team that discovered 'The Great Attractor." An atheist, Faber speaks like an evangelist as she weaves quantum physics and astronomy to describe the dawn of time. "I think that the story of the creation of the universe is the most inspiring and exciting story science can tell. I mean, who would have thought I could be telling you about events 10 to the minus 35 seconds after the big bang?" she said, seated in her cluttered, sunny UC Santa Cruz office amid photos of her two daughters and her husband. "It's just totally inspiring." " Mike Swift interviewing Faber, 'Last outer space repair of Hubble telescope pairs genius of two South Bay women', Contra Costa Times (California), May 9, 2009.
* Leon Festinger (1919–1989): American social psychologist famous for his Theory of Cognitive Dissonance."Festinger, a professed atheist, was an original thinker and a restless, highly motivated individual with (in his words) "little tolerance for boredom". " Franz Samelson: "Festinger, Leon", American National Biography Online, Feb. 2000 (accessed April 28, 2008) .. 
* Richard Feynman (1918–1988): American theoretical physicist, best known for his work in renormalizing Quantum electrodynamics (QED) and his path integral formulation of quantum mechanics . He won the Nobel Prize in Physics in 1965.Feynman was of Jewish birth, but described himself as "an avowed atheist" by his early youth in Freethought of the Day, Freedom From Religion Foundation, May 11, 2006."Having abandoned the tenets of Judaism at 13, he never wavered in his gentle atheism, nor in his determination to stay away from matters about which he had opinions but no expertise." John Morrish reviewing the collection of Feynman's letters Don't You Have Time to Think?, 'Particle Physics: The Route to Pop Stardom', Independent on Sunday (London), July 24, 2005, Pg. 21.
* Sigmund Freud (1856–1939): Father of psychoanalysis."[Freud and Jung] were close for several years, but Jung's ambition, and his growing commitment to religion and mysticism — most unwelcome to Freud, an aggressive atheist — finally drove them apart." Sigmund Freud, by Peter Gay, The TIME 100: The Most Important People of the Century.
* Erich Fromm (1900–1980): renowned Jewish-German-American social psychologist, psychoanalyst, and humanistic philosopher, associated with the Frankfurt School of critical theory."About the same time he stopped observing Jewish religious rituals and rejected a cause he had once embraced, Zionism. He "just didn't want to participate in any division of the human race, whether religious or political," he explained decades later (Wershba, p. 12), by which time he was a confirmed atheist."

He was also awarded the Wolf Prize in Physics in 1994/95."I am an atheist, that is, I think nothing exists except and beyond nature."Ginzburg's autobiography at Nobelprize.org
* Stephen Jay Gould (1941–2002): American paleontologist, evolutionary biologist, and historian of science, one of the most influential and widely read writers of popular science of his generation."Mutual respect means that religion and science should neither yearn for some mushy New Age synthesis nor ignore each other completely but engage in serious, sometimes heated, discussion and debate. This may seem a surprising ideal for a Jewish agnostic inclining to atheism who has fought long and hard against "creation science", but Gould develops it with his usual eloquence and wealth of intriguing examples." Matthew J Reisz, 'From Chaos to Last Trump', Independent on Sunday (London), February 11, 2001, News, Pg. 49.
* Susan Greenfield, Baroness Greenfield, CBE (1950–): British scientist, writer and broadcaster, specialising in the physiology of the brain, who has worked to research and bring attention to Parkinson's disease and Alzheimer's disease.What I don't like about Richard [Dawkins] is not so much what he knows or doesn't know as the dogmatic way in which he says things. I think that is a poor advertisement for science, because the whole thing about being a scientist is that you shouldn't be prejudiced, you should have an open mind. So, I don't believe in God but that is a belief, not some thing I know. I believe I love my husband, but I couldn't prove it to you one way or the other. How could I? I just know I do. My particular belief is that there is no Deity out there, but I can't prove it and therefore I would not have the temerity to tell other people they're wrong. The coinage of proof is not appropriate for belief and Dawkins thinks it is. But if you keep an open mind, that doesn't mean you swallow anything whole. As someone has said, 'Believing in anything is as bad as believing in nothing.' 'Brain Teaser: Susan Greenfield talks to Peter McCarthy', Third Way, November 2000.
* Jonathan Haidt (c.1964–): Associate professor of psychology at the University of Virginia, focusing on the psychological bases of morality across different cultures, and author of The Happiness Hypothesis."Religions are technologies that are evolved over millennia to do this and many religions are very effective in doing this. I'm an atheist, I don't believe that gods actually exist, but I part company with the New Atheists because I believe that religion is an adaptation that generally works quite well to suppress selfishness, to create moral communities, to help people work together, trust each other and collaborate towards common ends." Jonathan Haidt, Interview with Jonathan Haidt, Vox Popoli November 19, 2007 (accessed April 14, 2008).
* E. T. 'Teddy' Hall (1924–2001): English archaeological scientist, famous for exposing the Piltdown Man fraud and dating the Turin Shroud as a medieval fake."The three laboratories unanimously agreed that the cloth dated from between 1260 and 1390, a date consistent with its known history—but which demolished the notion of its being the burial shroud of Christ. Hall, who made no secret of his atheism, had no hesitation in enjoying the public attention that this definitive result attracted." Robert Hedges, 'Hall, Edward Thomas [Teddy] (1924–2001)', Oxford Dictionary of National Biography, online edition, Oxford University Press, January 2005 (accessed May 2, 2008).
* Sir James Hall (1761–1832): Scottish geologist and chemist, President of the Royal Society of Edinburgh and leading figure in the Scottish Enlightenment." 'Unequalled stability and sweetness of disposition' are said to have been among his domestic virtues, while in politics and religion he was 'a declared democrat and avowed atheist' (The Times)."

* Beverly Halstead (1933–1991): British paleontologist and populariser of science."He and the Bishop of Oxford staged another version of the great debate between Thomas Henry ('Darwin's bulldog') Huxley and Bishop ('Soapy Sam') Wilberforce that followed the publication of Darwin's Origin Of Species. The present Bishop defended the new Darwinian orthodoxy, but Dr Halstead, an atheist, took the line that the former Bishop of Oxford had been quite right to oppose Darwin's thesis. But that too was entirely characteristic. He told me that he was a member of the Athenaeum only because it had a painting of Darwin in the lobby." Tim Radford, 'A passion for dinosaurs: Obituary of Beverly Halstead', The Guardian (London), May 2, 1991.

* Peter Higgs (1929–): British theoretical physicist, recipient of the Dirac Medal and Prize, known for his prediction of the existence of a new particle, the Higgs boson, nicknamed the "God particle"."Officially, the particle is called the Higgs boson, but its elusive nature and fundamental role in the creation of the universe led a prominent scientist to rename it the God particle. The name has stuck, but makes Higgs wince and raises the hackles of other theorists. "I wish he hadn't done it," he says. "I have to explain to people it was a joke. I'm an atheist, but I have an uneasy feeling that playing around with names like that could be unnecessarily offensive to people who are religious." Ian Sample, 'The God of Small Things', The Guardian, November 17, 2007, Weekend pages, Pg. 44.
* Lancelot Hogben (1895–1975): English experimental zoologist and medical statistician, now best known for his popularising books on science, mathematics and language."A reader who has suffered me so far will have realised how much of my mental energy had been hitherto absorbed in a fruitless search for an intellectually compelling rationale to rescue some fragments from the wreckage of my family faith. The mood of liberation I experienced when I finally discarded the last remnant of theism was no less exhilarating than that of Bunyan's Pilgrim when the burden of sin fell from his back. [...] In retrospect, the final steps seem as sudden as they were painless. [...] As I looked upward [at the night sky], I realised that the sole prospect was limitless expanse of unthreatening and impersonal emptiness — but for unapproachable galaxies — of a universe without purpose of punishment or reward for a lately arrived animal species, free to make or mar its own destiny without help or hindrance from above."

* Nicholas Humphrey (1943–): British psychologist, working on consciousness and belief in the supernatural from a Darwinian perspective, and primatological research into Machiavellian intelligence theory."He has worked with monkeys in laboratories and in the wild. He has been a media don, a campaigner against nuclear weapons and the holder of a chair in parapsychological research who was dedicated to debunking even the possibility of telepathy or survival after death. He is an atheist, and the man who suggested to Richard Dawkins the analogy of viruses of the mind for religions; yet nowadays he talks as if spirituality were the thing that makes us human." Andrew Brown interviewing Humphrey, 'A life in science: The human factor', The Guardian, July 29, 2006, Review Pages, Pg. 13.
* Sir Julian Huxley FRS (1887–1975): English evolutionary biologist, a leading figure in the mid-twentieth century evolutionary synthesis, Secretary of the Zoological Society of London (1935-1942), the first Director of UNESCO, and a founding member of the World Wildlife Fund."Despite his atheism Huxley could appreciate Teilhard de Chardin's vision of evolution, and like his grandfather T. H. Huxley he believed progress could be described in biological terms."

* Steve Jones (1944–): British geneticist, Professor of genetics and head of the biology department at University College London, and television presenter and a prize-winning author on biology, especially evolution; one of the best known contemporary popular writers on evolution."Scientists in Britain, where the film will premiere at next month's London Film Festival, with general release in December, dismissed the intelligent design lobby's expropriation of the film. Steve Jones, professor of genetics at University College London and an atheist, said: 'I find it sad that people with intrinsically foolish viewpoints don't recognise this as a naturally beautiful film, but have to attach their absurd social agendas to it.' " David Smith, 'How the penguin's life story inspired the US religious right: Antarctic family values', The Observer, September 18, 2005, News Pages, Pg. 3.On the side of the atheists were Steve Jones, professor of genetics at University College London, [...] Jones, meanwhile, revealed that he would "love to believe in God", because it would offer some degree of comfort. But he said he stopped believing in God as a child as soon as he discovered that what he was learning in school biology classes conflicted with the kind of things he had been taught in Sunday school - like dinosaurs and humans walking the earth at the same time."

* Sir John Leslie (1766–1832): Scottish mathematician and physicist best remembered for his research into heat; he was the first person to artificially produce ice, and gave the first modern account of capillary action."In these years Leslie was an unsuccessful candidate for the chairs of natural philosophy at the universities of St Andrews and Glasgow respectively. He failed at the former because he was then an extreme whig and an atheist who deplored the Erastianism of many of the Scottish clergy."

* John Maynard Smith (1920–2004): British evolutionary biologist and geneticist, instrumental in the application of game theory to evolution, and noted theorizer on the evolution of sex and signalling theory.From a Humanist News interview in Autumn 2001: Interviewer: What is your attitude to religion now? JMS: Ever since reading (J. B. S. Haldane's book) Possible Worlds I have been an atheist, and a semi-conscious atheist before that. I think there are two views you can have about religion. You can be tolerant of it and say, I don't believe in this but I don't mind if other people do, or you can say, I not only don't believe in it but I think it is dangerous and damaging for other people to believe in it and they should be persuaded that they are mistaken. I fluctuate between the two. I am tolerant because religious institutions facilitate some very important work that would not get done otherwise, but then I look around and see what an incredible amount of damage religion is doing.

* Sir Peter Medawar (1915–1987): Nobel Prize-winning British scientist best known for his work on how the immune system rejects or accepts tissue transplants."... I believe that a reasonable case can be made for saying, not that we believe in God because He exists but rather that He exists because we believe in Him. [...] Considered as an element of the world, God has the same degree and kind of objective reality as do other products of mind. [...] I regret my disbelief in God and religious answers generally, for I believe it would give satisfaction and comfort to many in need of it if it possible to discover and propound good scientific and philosophic reasons to believe in God. [...] To abdicate from the rule of reason and substitute for it an authentication of belief by the intentness and degree of conviction with which we hold it can be perilous and destructive. [...] I am a rationalist—something of a period piece nowadays, I admit [...]" Peter Medawar, 'The Question of the Existence of God' in his book The Limits of Science (Harper and Row 1984).
* Jeff Medkeff (1968–2008): American astronomer, prominent science writer and educator, and designer of robotic telescopes."I met Jeff at The Amazing Meeting 5.5 in Fort Lauderdale in January. We became friends and I read his blog within hours of each posting. He was a programmer, an astronomer, a pro-bono science educator, a hard-nosed skeptic and an atheist. This random blow against a friendly and generous guy is a typical example of the non-plannedness of things."

* Desmond Morris (1928–): English zoologist and ethologist, famous for describing human behaviour from a zoological perspective in his books The Naked Ape and The Human Zoo."[Religion] is not an easy subject to deal with, but as zoologists we must do our best to observe what actually happens rather than listen to what is supposed to be happening. If we do this, we are forced to the conclusion that, in a behavioural sense, religious activities consist of the coming together of large groups of people to perform repeated and prolonged submissive displays to appease a dominant individual. The dominant individual takes many forms in different cultures, but always has the common factor of immense power. [...] If these submissive actions are successful, the dominant individual is appeased. [...] The dominant individual is usually, but not always, referred to as a god. Since none of these gods exist in a tangible form, why have they been invented? To find the answer to this we have to go right back to our ancestral origins." Desmond Morris, The Naked Ape, p.178-179, Jonathan Cape, 1967."Man's evolution as a neotenous ape has put him in a similar position to the dog's. He becomes sexually mature and yet he still needs a parent — a super-parent, one as impressive to him as a man must be to a dog. The answer was to invent a god — either a female super-parent in the shape of a Mother Goddess, or a male god in the shape of God the Father, or perhaps even a whole family of gods. Like real parents they would both protect, punish and be obeyed. [...] These — the houses of the gods — the temples, the churches and the cathedrals — are buildings apparently made for giants, and a space visitor would be surprised to find on closer examination that these giants are never at home. Their followers repeatedly visit them and bow down before them, but they themselves are invisible. Only their bell-like cries can be heard across the land. Man is indeed an imaginative species."

But he died in what amounted, for him, to a state of grace: resisting the one temptation to which almost everyone submits in the end, the temptation to believe... For most of the last decade of his life he engaged in a wide-ranging dialogue with religious leaders on the question...: does God exist? He argued the negative, although his formal position was agnostic, awaiting proof... 'You're so smart, why do you believe in God?' [Sagan] once exclaimed to [Rev.

* Frank J. Tipler (1947–): American mathematical physicist and professor at Tulane University.Although an atheist, Tipler believes 'God' will eventually exist in the last moments of the universe: 
"The theory is basically this: just as the Earth began with a Big Bang, so it will end, in a single point, which Tipler calls the Omega Point. And just as life on Earth began with a single cell which colonised the planet, so life at the end of time will, according to Tipler, "become omnipresent, omnipotent, and omniscient which are the three attributes of God". The Omega Point/God is the point of ultimate, infinite knowledge when the earth will be inhabited by beings who are, to all intents and purposes, computers. Tipler says they can be called beings because he defines life as information processing, as did the famous biologist Richard Dawkins, who called computers "biological objects". [...] 
Tipler says his own viewpoint is that of an atheist. Though brought up a Christian fundamentalist, he rejected religion when he was 16, because the Church claimed the Earth was 6,000 years old, when he knew that it went back 4.6 billion years. [...] 
Still, it seems excessively generous for the beings of the future to want to resurrect all of us. Tipler answers that they will be extremely intelligent beings, and therefore extremely curious, interested in all the variations that preceded them, from the very beginning, just as today's scientists are working to recreate the first single cell, in all its possible forms. "I think the evidence is very strong that this particular version of you and this particular version of me will actually be there in the future. It will be you and me emulated down to the atom." Why, he says, we might even end up repeating the whole interview."

In the pamphlet Turner declared that he was an atheist, though he did admit that the 'vis naturae', gravity, and matter's elasticity and repulsive powers demonstrated that the universe was permeated by 'a principle of intelligence and design' (ibid., 17).
