Brion Gysin invented the cut-up technique for altering prose which later was popularized by William Burroughs and later adopted by Robert Anton Wilson. (I think I've finally gotten that right, after screwing up in an earlier blog entry and attributing the technique to Burroughs.)
An entry on an Irish blog describes how in the early 1980s Gysin left Paris, stayed with Robert Anton Wilson for two weeks and then took a place of his own in rural Ireland. The bemused natives, who may not have been familiar with Gysin, were given a demonstration of his famous literary invention:
"He appears to have lived an idyllic life while there, going for long walks alone, befriending locals and going fishing with them and even spending one day helping them save turf on a nearby bog. He did not hide his more radical ideas from them either as one night in a nearby pub, Gerties in Keshkerrigan, he reportedly mutilated that week’s edition of the Leitrim Observer while demonstrating his cut-up technique at the bar. This incident was remembered with good humour when recounted to me by the owner of the bar who told me that the sentences he created were very humourous."
I found this entry after Nick Helweg-Larsen pointed me to this blog entry, which also concerned RAW and explained how Wilson inspired a writing project. Thanks, Nick!
