Isn’t a chemistry timeline already in Wikipedia somewhere? Anyway, here’s a couple of other related timelines/history sections that I have either written or worked on, that might be helpful:
Talk later: -- Sadi Carnot 16:39, 16 February 2007 (UTC)
If anyone has a problem with the following "early years" part:
It can be noted that both Isaac Newton, in his Chronology, and Michael Maier, as well as others, were using these Egyptian theories in the 1680s to formulate the chronological order of how the elements were formed as based on the descendents of the Ogdoad, such Ham, Misraim, Phut, Canaan, etc., each being associated with a different element. -- Sadi Carnot 18:16, 20 February 2007 (UTC)
User Jayron32 revered this change (which I made):
To this (which he thinks is correct):
Per the comment: “changed latent heat entry back to Thermodynamics. Though he never used the word, his discovery clearly belong in THAT field, not thermochemistry, something else entirely.” Jayron is clearly wrong in this matter. The science of thermodynamics did not begin until 1824. I will revert back with an added a source to justify the correct version. If Jayron has further issues with this semantics detail I will seek out further references. If this fails, I will seek out “request for comment” at the various WikiProject pages and with interested Users. I hope this will not be the case. -- Sadi Carnot 04:35, 21 February 2007 (UTC)
What is the basis for the division between the "industrial era" and the "early modern" era? Is this in common use, or based on a published work? And more importantly, is this relevant to the history of chemistry? In my opinion, no, as there was no major revolution in chemistry around 1850. If I had to divide the history of chemistry from the renaissance to today into periods, I would place one split around the time of Lavoisier or Dalton, and another around the time of Rutherford and Lewis (both of which curiously almost exactly match the centuries!). I'm also happy if the entire time after renaissance is treated as one period. But the current division seems arbitrary to me. Itub 08:32, 21 February 2007 (UTC)
Some of the entries in the list (including several that I added) could be considered inventions or theoretical developments rather than discoveries. I think these are perfectly fine and useful and I don't think they should be deleted, but maybe we could mention in the introduction that "discovery" is being used loosely and also includes some inventions and theoretical developments? -- Itub 09:48, 22 February 2007 (UTC)
Maybe this will be an unpopular opinion, but I don't think this article really needs references, except perhaps for controversial entries. Every entry here links both to the article about the scientist and an article about the topic, places where references either exist already or would be very welcome. But to duplicate those references here when they are just one click away will make this page twice as long (and unnecessarily IMO). Omitting references when only mentioning (and linking to) another article is common practice for "summary style" articles and is encouraged by the scientific citation guidelines in some cases. -- Itub 09:00, 23 February 2007 (UTC)
Ok, let's leave this discussion behind. A good source you can use to justify the importance of some of the discoveries in the late 19th and 20th centuries is http://nobelprize.org (in the case of discoveries that were rewarded with a Nobel Prize, of course). -- Itub 11:07, 28 February 2007 (UTC)
We have a few more entries to reference, certainly not more than a few dozen. Any more help would be appreciated. I plan to nominate this list for Featured status as soon as the referencing is complete. Thanks again for everyone's help so far... -- Jayron32| talk| contribs 04:05, 12 March 2007 (UTC)

User:KyraVixen removed a URL that was part of a reference to the first item in the "Early years" section. I tried to revert this as it was not an external link, but a reference to a source. I was prevented from doing this since that link appears to be spam listed. What goes? -- Bduke 05:25, 16 March 2007 (UTC)
I must confess that I had never heard of the Close-Packed Spheron Model. Apparently there's no wikipedia article about it yet. And the reference given (the Nobel website) doesn't seem to mention it either. Is it notable enough for this timeline? I haven't found anything yet to justify it, but I'd be happy to see some references (but even if it is notable, one could argue that it is a topic in nuclear physics). -- Itub 13:22, 16 March 2007 (UTC)
I must confess that I got it from the Wikipedia article on Linus Pauling, and would agree that a) its not that popular a model and b) probably not that significant of an event and should be removed. I will be doing so presently. -- Jayron32| talk| contribs 06:11, 17 March 2007 (UTC)
Referencing is pretty much done to the end ot the 19th century. Left to do:
*Reference the 20th century stuff
*Clean up all entries for consistent format and grammar
**Some entries have awkward prose, need to clean up a few*Maybe more pictures? Not sure we need them, looks good now.
*Nominate for Featured List when done all of above.
Any other ideas anyone? Looking good so far! --

What about the contributions from computational chemists? Maybe a note about density functional theory should be added. -- HappyCamper 11:54, 16 April 2007 (UTC)
I've added the entry for Heitler and London. I don't know about the Coupled-cluster yet, I'll have to think about it. A question I have is: what do people here think about moving Pauling, 1939 (publication of the book The Nature of the Chemical Bond) to 1931 (publication of the J. Am. Chem. Soc. article of the same name)? -- Itub 11:51, 12 June 2007 (UTC)
Some items to consider, which I'm undecided whether to add or not, are the olefin metathesis reaction, the Sharpless epoxidation, and the asymmetric hydrogenation reactions of Noyori and Knowles. There have been some questions about why there are no more recent developments on the list. An obvious place to look is the list of recent Nobel Prizes. However, most recent awards have been in areas that could better be considered as biochemistry or molecular biology, and are too specific for this list. I think the two most recent awards that could be considered "pure chemistry" are for the reactions I just mentioned (2001 and 2005). But did they really "significantly changed mankind's understanding of chemistry", as meant for a general list like this one? They are clearly important advances within their areas of chemistry, especially due to their practical utility, but should we start listing specific reactions? There are way too many important reactions, and the list could be swamped by them (maybe one day we will have a timeline of synthetic chemistry ;-). I have a hard time thinking of anything "earth-shattering enough" after the 1960s. -- Itub 12:23, 16 April 2007 (UTC)
Does there really need to be a listing for fullerenes 1985 and carbon nanotube 1991? Some of the suggestions above are good. Her is a list of subjects I would consider adding something on chiral catalysis, olefin metathesis, olefin polymerization, femtosecond spectroscopy, laser in general, multi-dimensional NMR, more specifically protein NMR, density-functional theory, integrated circuit, or Marcus theory would be worth adding.-- OMCV ( talk) 06:34, 18 May 2008 (UTC)
I just read the list, and I found it great. Every major event in Chemistry is clearly mentioned and explained, however, I noticed that the events involving Arab and Persian chemists are rather vague (here's the dates :750, 850, 1000 & 1377). Most of them contain only this sentence ...refutes the practice of alchemy and the theory of the transmutation of metals., which seems to be copy-pasted. It would be better if you add more explanation as to what works these chemists have done to lead them to this conclusion and what are their exact contribution to chemistry. Thank you. Eklipse ( talk) 15:02, 15 June 2008 (UTC)
the history of chemistry; Making colored pigments for use in paintings and cosmetics • Fermenting grain and fruit into beer and wine • Converting milk into cheese • Making dyes • Rendering fats into soap • Producing pottery, enamel and glazes • Separating copper and other metals from their ores • Making alloys like bronze • Making glass • Separating useful chemicals from plants for use as medicines if some one could date these and add them it would help the article. J8079s ( talk) 20:12, 13 November 2008 (UTC)
The covering of the arabs and persian alchemists in the article is really a disgrace, full of mistakes and distortions. Many claims of discovery are simply wrong, and they are backed and questionable sources like "The making of humanity", the "famous muslims" website, "the science and technology in Islam" website (a site with a political agenda, owned by the same guy of "Muslimheritage"), and the books of the mentally unbalanced arabist Paul Kraus.
All of the subtances attributed to Geber were really discovered by an anonymous 13th century alchemist called "Pseudo Geber". Nitric acid, aqua regia, Sulphuric acid and all those things were discovered by him, not by Geber. Sulfuric acid was discovered by other alchemists like Vincent of Beauvis and Albertus Magnus, because the arabs only worked with vitriol (not the same as sulfuric acid).
Similarly, the distillation of wine was never done by arab alchemists. Not even by the greeks who were the inventors of distillation. Serious science historians give the priority to the school of salerno in the 12th century.

There was a thread at WT:CHEM#Timeline of chemistry potentially on Main Page about this list, and having looked at the article, I am unsure about (a) what criteria are being used to select information for inclusion (or exclusion) and (b) relatedly, the issue of completeness of the list. Reproduced from that discussion, here are some discoveries / achievements that I can think of that might be worth including:
I am sure there can be disagreement about some of these, and have no doubt that other chemists will have other suggestions for editing the list. Thoughts? EdChem ( talk) 08:42, 14 January 2011 (UTC)

I can't understand why Hermes Trismegistus appears in the timeline at "c. 1900 B.C.". The cited reference contains no mention of this period. Instead, the reference states: It was to this powerful god that the Egyptian Hermeticists of the second and third centuries A.D. joined the image and especially the name of the Greek Hermes. From this time onward the name "Hermes" came to denote neither Thoth nor Hermes proper, but a new archetypal figure, Hermes Trismegistus, who combined the features of both. Thus, it seems to me that "c. 200" (AD) should be more correct. -- Albris ( talk) 14:36, 27 April 2014 (UTC)

If anyone has a problem with the following "early years" part:
It can be noted that both Isaac Newton, in his Chronology, and Michael Maier, as well as others, were using these Egyptian theories in the 1680s to formulate the chronological order of how the elements were formed as based on the descendents of the Ogdoad, such Ham, Misraim, Phut, Canaan, etc., each being associated with a different element. -- Sadi Carnot 18:16, 20 February 2007 (UTC)
