Lionel Snell is among the founding names in chaos magic - though better known as Ramsey Dukes. In 1970 Gerald Yorke (keeper of the Crowley archive) introduced him to the writings of Austin Osman Spare and he wrote "Spare Parts" - an introductory article about Spare's system of magic - which was published in Agape 4 in 1973 together with a facsimile of Snell's copy of  The Anathema of Zos. This, together with his first self-published books SSOTBME - An Essay on Magic and Thundersqueak played a seminal role in the nascent Chaos current. He is also known for his contribution to cyber magic, having already pioneered the 'information universe' concept twenty years before The Matrix.
