18 1/2 Minutes: The Erasure of Watergate Tape 342

(Ticket holders only)

Hear the infamous gap in the tape that sealed the fate of US President Richard Nixon exactly 50 years ago – FREE with regular admission!

On 20 June 1972, Richard Nixon recorded himself having a conversation that likely contained damning proof of his role in the cover-up of the Watergate Hotel break-in, a scandal that would ultimately lead to his resignation. When congressional investigators became aware of the conversation and subpoenaed the tape, they discovered that someone had erased eighteen and a half minutes of the tape.

The erasure was studied by audiology experts and a report produced, documenting at least four or five separate erasure events on the magnetic reel-to-reel tape. It was sloppy. Many suspected – due to his well-known technological incompetence – that Nixon himself erased it.

But the erased portion of the tape was not silent; far from it.

Multiple attempts have been made in the half-century since to extract the original contents of ‘the 18 1/2 minute gap’ as it came to be called. So far, all have failed.

This summer, the Museum of Portable Sound presents this erasure as the basis for a summer blockbuster exhibition marking the 50th anniversary of the Watergate break-in scandal.

18 1/2 Minutes: The Erasure of Watergate Tape 342 allows visitors to hear the entire erasure for themselves while perusing (and downloading!) once-secret US government documents and other paraphernalia that can only be unlocked on our website via a unique secret password.

Visitors only have access to the materials for the duration of the 18 1/2 minute recording.

The longer you listen, the more you will learn.

18 1/2 Minutes: The Erasure of Watergate Tape 342 is NOW OPEN for the remainder of Summer 2022.
