In the mid-1950s there was a confluence of events that were the harbingers of dramatic changes to the American scene. We now live within a landscape that was the product of changes initiated more than three-quarters of a century ago.

Helphand's presentation will explore seven mid-century phenomena between 1954 and 1957 that now symbolize our contemporary culture and environment, affecting us daily: the interstate highway system; McDonald's; Disneyland; the architecture of Victor Gruen; the Boeing 707; the westward migration of the Dodgers and Giants; and the growth of suburbia.

These developments had radical and long-lasting impacts some of which were anticipated, but more often they were unforeseen. These developments are now so commonplace that we take them for granted. We live within this midcentury Modern landscape. It is all around us, yet we rarely think of how it came to be.
