Doc Talk Podcast Debates Oscar Nominations, Heads To Sundance For Documentary ‘Ghost’ Story And More

When the Oscar nominations were announced last week, all five nominees for Best Documentary Feature premiered at the Sundance Film Festival.

Deadline

Josef Carl Engressia Jr., aka: Whistler, later known as Joybubbles, was a blind phone phreaker with the extraordinary gift of absolute pitch. He could whistle a perfect 2600 Hz tone, the exact frequency needed to manipulate AT&T’s phone system. Without using any devices, he could seize control of long-distance calls just by whistling into the handset.

In 1971, Engressia became the first phreaker to face legal consequences when he was arrested and fined twenty-five dollars for phone fraud. Despite this, he remained a legendary figure in phreaking culture. Later in life, he legally changed his name to Joybubbles.
