Charles Wright Mills was an American sociologist, and a professor of sociology at Columbia University from 1946 until his death in 1962. Mills published widely in both popular and intellectual journals, and is remembered for several books, such as The Power Elite, White Collar: The American Middle Classes, and The Sociological Imagination. Mills was concerned with the responsibilities of intellectuals in post–World War II society, and he advocated public and political engagement over disinterested observation. One of Mills's biographers, Daniel Geary, writes that Mills's writings had a "particularly significant impact on New Left social movements of the 1960s era." It was Mills who popularized the term New Left in the U.S. in a 1960 open letter, "Letter to the New Left".

The Power Elite is a 1956 book by sociologist C. Wright Mills, in which Mills calls attention to the interwoven interests of the leaders of the military, corporate, and political elements of society and suggests that the ordinary citizen in modern times is a relatively powerless subject of manipulation by those three entities.
