Robert A. Dahl

Robert Alan Dahl (/dɑːl/; December 17, 1915 – February 5, 2014) was a political theorist and Sterling Professor of Political Science at Yale University. He established the pluralist theory of democracy—in which political outcomes are enacted through competitive, if unequal, interest groups—and introduced "polyarchy" as a descriptor of actual democratic governance. An originator of "empirical theory" and known for advancing behavioralist characterizations of political power, Dahl's research focused on the nature of decisionmaking in actual institutions, such as American cities. Dahl is considered one of the most influential political social scientists of the twentieth century, and has been described as "the dean of American political scientists."
