The Thomson Reuters media group published this ranking in the International Year of Chemistry to celebrate the achievements of the chemists who were particularly often cited and thus exercise the greatest influence on scientific progress. The minimum requirement for inclusion in the ranking was at least 50 scientific publications since February of 2000. The most represented countries are the United States followed by Germany and Great Britain. Thomson Reuters published the ranking as part of its scientific information service ScienceWatch.com.
