Megan sighs:
It's odd that an entire American accent disappeared virtually overnight: the upper class American accent that covered not only the northeastern seaboard, but California as well. Some of my friends parents had it, and a few famous people are still hanging on, like former New Jersey governor Tom Kean. But the accent of the Roosevelts, Julia Child and Katherine Hepburn pretty much up and vanished sometime in the late 1950s.
