Some events that transform a nation are frozen in time. Others pass with little public awareness, and we only appreciate their momentous nature long after they occur. Regardless, these events are few and--almost always--far between. But in 1969, four such events took place within the span of only 100 days. In this book, cultural historian Harlan Lebo looks back at the first moon landing, the Manson family murders, Woodstock, and the birth of the Internet to tell the story of how each event shaped the nation and how we perceive ourselves. Loaded with captivating anecdotes and insights based on extensive interviews with eyewitnesses and participants, to provide historical insight and contemporary context, 100 Days will fascinate readers who seek a deeper appreciation of how four seemingly unrelated events shaped America's emergence as the nation we have become.
