Clarivate Unveils Citation Laureates 2021 – Annual List of Researchers of Nobel Class

This year’s list includes 16 new Citation Laureates from institutions in six countries: France, Italy, Japan, Korea, Singapore, United States

59 Citation Laureates named by the Institute for Scientific Information have gone on to receive a Nobel Prize


London, U.K., September 22, 2021: Clarivate Plc (NYSE:CLVT), a global leader in providing trusted information and insights to accelerate the pace of innovation, today named 16 world-class researchers from six countries as Citation Laureates™. These are researchers whose work is deemed to be ‘of Nobel class’, as demonstrated by analysis carried out by the Institute for Scientific Information (ISI)™.

Each year since 2002, ISI analysts have drawn on Web of Science™ publication and citation data to identify influential researchers in the research areas recognized by Nobel Prizes: Physiology or Medicine, Physics, Chemistry and Economics. Out of some 52 million articles and proceedings indexed in the Web of Science since 1970, only 6,500 (or .01%) have been cited 2,000 or more times. It is from the authors of this group of papers that Citation Laureates are identified and selected. They are individuals whose research publications are highly cited and whose contributions to science have been extremely influential, even transformative.

In early October 2021, the Nobel Assembly will vote to confer science’s highest honor. While this annual rite inspires worldwide speculation, Clarivate is the only organization to use quantitative data in addition to qualitative assessment to provide valuable insights about who might be chosen. To date, 59 Citation Laureates listed in the Hall of Citation Laureates have gone on to receive a Nobel Prize.

Joel Haspel, SVP Strategy, Science, Clarivate said: “This year’s Citation Laureates have pioneered some of the most important research of our time, accelerating our understanding of subjects as varied as free radicals, virus identification and financial crises. It is because of their foundational work that the pace of innovation in drug development, economic theory and entrepreneurship can continue to progress. We are delighted to recognize and celebrate their enormous achievements, demonstrating that their citation records reflect their influence on their colleagues, research fields and society as a whole.”

Commenting on his recognition as a Citation Laureate, Joel Mokyr, Robert H. Strotz Professor of Arts and Sciences and Professor of Economics and History at Northwestern University said: “In Adam Smith’s The Theory of Moral Sentiments, he says the main reason why people work so hard and go through all this trouble is they want other people like themselves to respect them. So being recognized by Clarivate as a Citation Laureate tells me that at least somebody is paying attention to my work, and that makes me feel very good. People have this inner need to be recognized by people like themselves, and I think peer recognition is therefore a big driver of all kinds of science in the world today – and that’s been a great blessing because it’s science, of course, that has brought us where we are.”

David Pendlebury, Senior Citation Analyst at the Institute for Scientific Information at Clarivate said: “For a paper to be cited 2,000 times or more is a rarity. Authors of very highly cited papers are usually members of national academies of sciences, hold senior appointments in universities and other research institutes, and have received many top international prizes in their fields. Indeed, many of them have helped to shape their fields of study. Some of these ‘scientific elites’ go on to receive Nobel honors, demonstrating each year the association between citations in the literature, influence through a research community, and peer judgement.”

This year nine of the 16 honorees are based at leading academic institutions in the United States, three are based in Japan, and others hail from France, Italy, Korea and Singapore.
