Theater and the Atomic Age

As with all types of art, works of theater tend to reflect the preoccupations of the society in which they are made. Because of this, it is unsurprising that stories about nuclear weapons have proven frequent fodder for dramatization in the twentieth and twenty-first centuries. This article provides a brief guide to some of the more notable plays that have tackled topics related to nuclear history. Interestingly, a majority of these works are from the past few decades. This may signal a recent, renewed cultural interest in nuclear weapons and the early decades of the Atomic Age.
