I collected over 20 lists of the greatest/most important scientists of all time and compiled them into one meta-list. The results are below: every scientist on two or more of the original source lists, organized by rank (that is, with the scientists on the most lists at the top). Where there are multiple scientists on the same number of lists, they are arranged chronologically by date of birth.
NOTE: These are not my personal opinions.

Wrong information than other sites .Albert Einstein and Issac Newton should be held high than others
Mr. Suman Das: Thank you for your feedback. Just to be clear, this list is not my personal opinion about the greatest scientists of all time. It is a compilation of numerous lists I found in books and on the Internet. The scientists at the top of the meta-list you see on my website are not there because they are greater than the other scientists on the list. They are at the top because they are on more lists of “greatest scientists” than the other scientists.
Why no Ramanujan bro ? And Aryabhatta too .
Good question, Karthik. I don’t know why they didn’t make it onto enough source lists to make it onto the meta-list. I re-do the list every few years, so they may make it in the future.
I want to know the criteria for the ranking because we know How significant Newton Eisten ,Bacquerel has been to science. Yet your ranking doesn’t potray that
Thanks for your comment! These are not my personal opinions but they are the collected wisdom of 20 different list-makers who made “best scientists of all time” lists. The greatest scientists of all time meta-list was created by collecting lists of “greatest scientists of all time” – I found 20 lists in books and on the Internet. Then I compiled these lists into one meta-list, by giving one point to each scientist for each list they were on. Einstein was on 19 of the lists I found, so he goes at the top of the meta-list in first place. Newton, Galileo and Marie Curie were all on 17 of the 20 lists, so they are tied for second place. Becquerel was only on 2 of the lists, so he is near the bottom of the meta-list, far below Einstein and Newton.
wrong list;first is newton,then einsten, galileo,much before currie and hawkins done done much shuold be on bottom, tesla is more inventor than scientist.
Peter: Thanks so much for your feedback. Characterizing the list as “wrong” seems a bit harsh, but you are entitled to your opinion. As I see it, one of the fun things about lists is the opportunity to agree or disagree with the list. I don’t take your criticism personally because these are not my personal opinions. This is a meta-list, which means it is a compilation of many lists made by others in books, magazines and websites. So technically, the names at the top are not the “best” scientists but the scientists on the most “best scientists” lists.
Great list, fantastic help while choosing which scientists to research for a school project, thanks!
Where is Lorentz?
I was also disappointed that Lorentz didn’t make the meta-list.
Actually, I misspoke. Lorentz is on the chronological list, which is longer than the ranked list: https://beckchris.wordpress.com/science-nature-technology/greatest-scientists-of-all-time/the-greatest-scientists-of-all-time-chronological/
Thanks for the feedback, Mike!
Eratosthenes – the greatest scientist ever
worked out 2220 years ago:
may have been the first to use the word geography. He invented a system of longitude and latitude and made a map of the known world.
He also designed a system for finding prime numbers — whole numbers that can only be divided by themselves or by the number 1.
invented a system of latitude and longitude, and a calendar that had leap years.
He also invented a mechanical device that astronomers used for many years to figure out where the stars were in the sky how they appeared to move (as the Earth turns). That device was called the armillary sphere
• He was the first person to explain why the River Nile flooded every year – i.e. heavy, seasonal rains fall near the source of the river causing an annual flood in Egypt.
• He rejected the commonly held view that people could be divided into ‘Greeks’ and ‘Barbarians.’ He thought people should be judged as individuals on their good and bad qualities.
in about 240 BC Eratosthenes calculated Earth’s size with good accuracy. This was a moment of triumph for the human intellect: first to recognize our planet is a sphere, then to use the powers of observation, deduction, and mathematics to calculate its size.
I am also surprised that Eratosthenes did not make the meta-list!
While I understand your methodology, and this list is not terrible, in fact the best I have seen so far, I propose a different methodology. Use lists of the greats of each field, then weight them by the number of doctorates regularly awarded in each field. Of course, picking what is a field and what is a sub-field might be treacherous, but I still think the results will be better. And the lists of greats should be compiled by people intimate with those fields. This could bias results toward the last hundred and fifty years, and skip especially people from ancient times. But still better, in my opinion. Consider that probably the greatest psychologist is not on this list: B.F. Skinner, yet others are: Freud, and Pavlov. Piaget should also be there. In chemistry Robert Burns Woodward and Gilbert N. Lewis should be present. In geology Nicolas Steno invented geology. But he is a no show. No Oceanographers. Robert S. Dietz, Bjørn Helland-Hansen and Henry Melson Stommel could be candidates.
Other than missing very important scientists, the biggest problems I am seeing are 1.Inclusion of engineers and inventors. These are very important people with great contributions, but the topic is “scientists”. 2.Inclusion of mathematicians. Again great contributors…but not scientists. Computer “scientists” are also mathematicians or engineers. I can’t understand this trend. Science is about making hypotheses and collecting data to give support inductively. Anything else is not science. 3.Trying too hard to represent women/minorities. It is wonderful to show that a variety of people can contribute greatly, but intellectual honesty is more critical in my opinion. And I am not saying women don’t belong on this list, certainly some do…just that there is a distortion. 4.leaders of projects, but not necessarily people who did the science or even the theorizing. I suspect even on the lists of field greats, this is not going to drop away. And credit hogs are bountiful, though inventors are the most prone to this. Bell, Edison and Marconi are all usurpers to varying degrees. 5.Bias toward including more physicists and astronomers. 6.Including science popularizers rather than big thinkers and doers.
Noodle-Naut: Thanks so much for the excellent feedback! I appreciate the points you make here. Your alternate methodology would definitely make for an interesting, perhaps better list. It is interesting to me that so many of the people who created “Best Scientists” lists included inventors, mathematicians and engineers. I guess different people define “scientist” differently. Since my job as a meta-lister is to collect and combine the lists other people make, I don’t have much input into how they define their subject. One of the interesting things about lists (in fact, I think it is one of their main purposes) is to spark conversations about what should be on the list that isn’t and what is on the list that shouldn’t be. I like the idea that these discussions can be open-ended with no definitive “right” answer. I recognize that the meta-list methodology I use is not perfect, but I’m sticking with it for now. I would love to see your list of the best scientists of all time! – John B.
Can you please send me the link of all the lists you have encountered? You took a base list, and based on this list you numered how many the names of this list appear on other lists, am I right? But I would like to know all the names from all the lists, not just your base list. That is why I am asking for all the lists, because I myself want to do a meta-list based on this.
I’m asking that because I have my personal list of cientists (I am an afctionate for lists too) and I am trying to make the best possible list I can. I would be very thankful if you provided me the lists.
Sir, I am so sorry to disappoint you but I did not keep close track of all the lists I found so I am unable to provide them to you. Most of them you could find yourself by Googling “Best Scientists of All Time” or “Most Important Scientists of All Time.” There are many lists available online and also in books at your local library. I am so glad you enjoy making lists, and I look forward to seeing your meta-lists of the best scientists. Please note that I haven’t updated my meta-list since 2017 so there may be new lists out there to collect. I wish you the best of luck!
I don’t have a meta-list yet, but I have a personal list of the 100 most important scientists of all time. Do you have this kind of list too? If so, can you post it for us to see it?

Idade Antiga: 2
Lucas: This is excellent! Thanks for sharing it with us!
the list is great. but is there a way to display the list from the oldest (the first invention) to the newest. I rather see how things evolve. I believed the first science came from the far east and the middle east before the European expanded on those one. – thanks.
Miguel: Here are two lists that are chronological (oldest to newest):
thanks so much Beck Chris. this is great!!!
Most interesting !! As a young scientific researcher, I had often wondered why there was no attempt to prepare a list of this nature. About 15 years ago, I had an opportunity to interview Sir Paul Nurse , the then President of the Royal Society and he revealed that there was indeed an effort in this direction. Philip Barker had written a book called TOP 1000 SCIENTISTS;FROM THE BEGINNING OF TIME TO 2000 AD which was available in the Royal Society Library which had results from inputs from 80 universities across the world and had a list of this nature. I had to leave for Stockholm to commence my fellowship the very next day hence could not visit the Royal Society Library, but made it a point to ask for it at the Nobel Library . Lo and behold, it was there in the reference section-and I have checked ; it is still there. I recall it had a foreword by Professor Ludmilla Jordanova. And if my memory serves me right, most of these names were there.
Gerald- I’m going to try to find that book so I can add that list to my meta-list. Do you know if it’s available in the U.S.?
I looked up the Amazon. I think it is still available. And I note on the net that it is still in the reference section of the Nobel Library . My understanding is that the library is extensively used by the different Nobel Committes https://lib.nobelbiblioteket.se/search*swe/?searchtype=t&SORT=D&searcharg=top+1000+scientists+
The criteria is good. however, the lists do not include great scientist such as Al-Razzi whose works in medicine are unsurpassed. , Al- Jazzri whose works entitled him to be the father of the Robots.
You made the common mistake of equating engineering with science. For instance, Edison was not a scientist he was an engineer and businessman who stole most of his “ideas” from others. You also have listed a number of other engineers and “managers” who’s actual scientific contributions do not put them in the highest ranks. You list very few people in the Earth sciences and totally miss James Hutton (uniformitarianism, deep time, etc.). He should be in the top 20 in terms of his impact on how we understand the universe. He was a primary influence on both Charles Lyell and Charles Darwin, who you do manage to list.
Thanks for the feedback, Jay. You make some really interesting points here. Unfortunately, I have little control over what names go into the meta-list. That is determined by the people who make the original source lists who make up my meta-lists. As is clear from your comment (and some others), the people who make “Greatest Scientists of All Time” lists apparently have very different (and in some cases, according to you, incorrect) definitions of “scientist.” A meta-list is only as good as the lists that were used to make it. If you can direct me to some lists of “Greatest Scientists” that use your definition of “scientist”, I would appreciate it. As for James Hutton, I, too, am surprised he wasn’t on more of the original source lists of Greatest Scientists. If I find his name on more lists, I will include him in the meta-list.
