Robert Alan Dahl was the Sterling Professor emeritus of political science at Yale University, where he earned his Ph.D. in political science in 1940. He was past president of the American Political Science Association. Dahl was sometimes described as "the dean of American political scientists". His research focused on the nature of democracy in actual institutions, such as American cities. His influential early books included A Preface to Democratic Theory, Who governs?: Democracy and power in an American city and Pluralist Democracy in the United States all presented pluralistic explanations of who rules in America, arguing that many competing groups shared power. He died in 2014, aged 98.
