The Most Influential People Across History
Find the most influential people in 24 academic disciplines and numerous subdisciplines
Find famous and important people related to your research. This is an excellent tool for research papers, topic papers, and building a bibliography. Using our influence-based algorithm, our rankings synthesize data from Wikipedia, Wikidata, Semantic Scholar, and CrossRef.
Students and researchers now have a fast and reliable way to find influential thinkers from 24 disciplines and 300 sub-disciplines (and growing). If you want to find history’s most influential philsosophers, or the world’s most influential mathematicians currently, now you can.
We also provide custom rankings of people by discipline as well as interviews with influential academics who are currently active.
To use this tool, select the discipline (and optional subdiscipline) relevant to your research, and specify influential academics by history, world, or US. Even results that are counterintuitive are often enlightening (our algorithm always picks up a signal).
