The Top 10 Organic Chemists of All-TimeApril 16th, 2006
This post originally appeared on www.paulbracher.com
Here’s my list of the top 10 organic chemists of all-time, without regard to nationality or sub-specialty. I’m sure that the list is biased towards academic chemists, because their triumphs tend to be more heralded, but I’m sure most of them took plenty of money from industry, too.
10. George Olah
Olah was a giant in the field of physical-organic chemistry and the study of reactive intermediates. With his development of superacids, he was able to study carbocations and essentially end the debate about the existence of nonclassical ions. He has also been celebrated for his work in organofluorine chemistry and organic synthesis.
9. Carl Djerassi
The “Father of the Pill,” Djerassi’s synthesis of the progestagen norethindrone had huge medical and societal consequences–people of the ’60s and ’70s should thank him for all of the uninhibited sex they enjoyed. Because Djerassi’s pill work can be viewed as a nice, tight package with a profound practical application, I think he’s still got a good shot at picking up a Nobel Prize someday.
8. Paul D. Bartlett
The Bartlett Lab was a physical organic powerhouse, and Frank Westheimer said Bartlett “dominated that field for perhaps four decades.” Bartlett hammered home the concept of using kinetic and stereochemical studies to determine mechanisms, and he elucidated the two-step mechanism of electrophilic additions to olefins and the free radical mechanism of certain polymerizations. He also made important contributions to the study of carbocation stabilization (he synthesized 1-bromonorbornane), hydride transfer, and kinetic vs. thermodynamic control of reactions. Perhaps most importantly, Bartlett is credited with changing the way organic chemistry is taught by introducing the mechanistic perspective that we use today.
7. Sir Robert Robinson
The man made the field of natural product synthesis popular. While he might be condemned for this today, for the latter half of the 20th century, the field drove the discovery and development of new reactions in organic chemistry. His one-step synthesis of tropinone is legendary, and he made fundamental contributions to the structural elucidation and synthesis of steroids, alkaloids, and dyes. He is also credited with inventing the arrow formalism (electron pushing) approach to drawing reaction mechanisms.
6. Jack Roberts
Roberts made numberous contributions to the field of physical-organic chemistry, including his studies of cyclopropylcarbinyl systems and molecular rearrangements. Roberts played a major role in popularizing the use of MO theory among organic chemists and he coined the terms “nonclassical carbocation” and “benzyne.” More importantly, the man essentially brought NMR to organic chemistry. In addition to showing chemists how to use the method to elucidate structure, he pioneered the use of isotopic labels to monitor reaction mechanisms. Despite the fact that NMR is still the single most useful method for the characterization of organic compounds, he hasn’t yet been rewarded with a Nobel Prize. I ask you, where is the justice?
5. H.C. Brown
Sure he won the Nobel Prize for his work with hydroborations, but his contributions to physical-organic chemistry were just as important as those to synthesis. His epic battles with Saul Winstein over the nature of carbocations (classical vs. nonclassical) forced chemists at the time to think critically about how to disprove a mechanism and the existence of a particular reactive intermediate. Of course, Brown’s position on nonclassical ions proved to be wrong, but he made the field better nevertheless.
4. Adolf Johann Friedrich Wilhelm Ritter von Baeyer
Trained by Bunsen and Kekule, Baeyer would go on to win the Nobel Prize in 1905 for his work on aromatic compounds and dyes, which were important at the time for the chemical industry. He is especially famous for his work with indigo. He also synthesized phenolphthalein, fluorescein, and barbituric acid. He studied lactams, terpenes, purines, and polyacetylenes, and conducted seminal work on ring (Baeyer) strain. He also introduced the concept of tautomerization. Baeyer did it all, including training three future Nobel laureates (Fischer, Buchner, and Willstatter) and numerous other famous chemists.
3. Emil Fischer
The German chemist is responsible for developing a number of fundamental synthetic methods, including the Fischer indole synthesis, the Fischer oxazole synthesis, and Fischer esterification. Fischer laid the basis for the entire field of carbohydrate chemistry. His proof of the structure of glucose was a tour de force and don’t forget about his Fischer projections (and his lucky guess). He essentially gave his life to chemistry, as the compounds he worked with literally drove him insane.
2. E.J. Corey
The man is a machine, churning out countless total syntheses, new reaction methods, and well-trained chemists with frightening efficiency. In 2002, he was dubbed “the most cited author in chemistry” by the ACS. His progeny populate both the upper levels of academia and the pharmaceutical industry, and at 77, he’s still going strong.
1. R. B. Woodward
The man is a legend–he revolutionized the fields of structural determination, organic synthesis, and physical-organic chemistry. The Nobel Committee essentially bestowed a lifetime achievement award on him with the ‘65 Prize for “outstanding achievements in the art of organic synthesis,” and he would have won a second in ‘81 for orbital symmetry had he not died in 1979. Some, including Woodward himself, thought that he deserved to share in the ‘73 Prize for the “chemistry of organometallic compounds.” On top of all this, he could drink any other chemist under the table. Salud.
Others meriting consideration (in no particular order): Gilbert Stork, Sir Christopher Ingold, George Hammond, Linus Pauling, Donald Cram, Jean-Marie Lehn, Justus von Liebig, Sir Derek Barton, William von Eggers (the “Bull”) Doering, August Wilhelm von Hofmann

April 16th, 2006 at 9:57 pm Don’t forget the frenchies, without regard to sub-specialty,Francois Auguste Victor GrignardLouis Pasteur
French fries are now called freedom fries, we know, but not in the rest of the world….

April 16th, 2006 at 11:11 pm K. Barry Sharpless….Saul Winstein….pretty good list though.
- Paul Says:
April 17th, 2006 at 12:03 am Hmm…I’ve never heard of Percy Lavon Julian. Interesting, but I don’t think he cracks the top 10.Grignard was a one-hit wonder. Pasteur was an awesome scientist, definitely top 10, but I don’t know whether he can be considered a top 40 organicchemist.Saul Winstein should go on the considerations list. I don’t know about Sharpless…I’ve been thinking about a top 10 living, non-emeritus list but there are few clear choices.

April 17th, 2006 at 9:48 amThis is an interesting list. I’ve heard of all of them, but evidently my background isn’t sufficient enough to appreciate all of their contributions (except for the really big names).If you like the historical perspective, you’d really like the book “Chemical Creativity” by Jerome Berson. I’m about half-way through it, and it’s a fascinating read. I’ll bet the Harvard library has it.Anyone have a recommendation for a good book to re-teach myself the “stereoelectronic / MO” approach to mechanism? What little I learned of it in the beginning of my PhD has long since been forgotten.

April 17th, 2006 at 5:59 pm Jordan – Fleming’s “Frontier Orbitals and Organic Chemical Reactions” is good for MO.

April 17th, 2006 at 9:26 pmCan’t second CW enough. Picked it up a few months ago; great read and best explanation of hard/soft ever.
- Jordan Says:
April 18th, 2006 at 11:40 am Thanks for the recommendations. They adopted Fleming at my school the year after I took the grad school organic courses. (We were somehow just “expected to know it” coming out of undergrad.) I’ll seek it out. Cheers to all of you.

April 19th, 2006 at 11:27 am I think Peter Dervan could be on the list. I do not think people like Schreiber or Schultz, etc. etc. would be following quite the same path without Peter. Regarding EJ and RBW, I like to make the analogy to students that EJ is Beethoven to RBW’s Mozart. Both are geniuses, but with EJ one has the feeling that if you just could concentrate long enough and hard enough you might come up with just one of his discoveries. But against Woodward, you could never be in the game.

April 20th, 2006 at 2:03 amMy undergrad advisor worked for Corey. He used to compare Corey and Woodward to Batman and Superman. If you had all the gadgets, you could believe that you too could be Batman, but Superman, NEVER.

April 20th, 2006 at 8:00 am […] Putting that list together about the all-time top 10 organic chemists got me thinking about who’s going to win the chemistry Nobel this year (or any year). Since 2000, everyone’s annual guess was olefin metathesis and it finally won. Now that the low-hanging fruit’s been picked, the race is wide open. Below, I’ve thrown out some names and topics that could be recognized this year. I’m doing this on the fly, so I’m sure it’s incomplete…fill in the blanks and we can set odds when we’ve got a complete list of candidates. […]
