Frederick Lewis Allen was one of the pioneers in social history. Best known as the author of Only Yesterday, Allen originated a model of what is sometimes called instant history, the reconstruction of past eras through vivid commentary on the news, fashions, customs, and artifacts that altered the pace and forms of American life.

The Big Change was Allen’s last and most ambitious book. In it he attempted to chart and explain the progressive evolution of American life over half a century. Written at a time of unprecedented optimism and prosperity, The Big Change defines a transformative moment in American history and provides an implicit and illuminating perspective on what has taken place in the second half of the twentieth century.
