Paul R.A. De Giberne Sieveking (born 1949) is a British journalist and former magazine editor.
Until 2002, Sieveking was co-editor of the magazine The Fortean Times with its founder Bob Rickard. He joined the UK-based "Journal of the Unexplained" in 1978. His father, Lancelot "Lance" De Giberne Sieveking was an early BBC radio and television drama pioneer, and his half-brother Gale De Giberne Sieveking was an archaeologist.
Sieveking was born in London in 1949, the son of writer/broadcaster/producer Lance Sieveking. He attended Jesus College, Cambridge, where he read anthropology, graduating in 1971.
He subsequently produced the first English translation (with John Fullerton) of Raoul Vaneigem's The Revolution of Everyday Life, which was published by Practical Paradise Publications in 1975.
Sieveking was introduced to FT-founder Bob Rickard by mutual friend Ion Will in 1978, some five years and more than 25 issues after it was first self-published as The News in 1973, before becoming Fortean Times in 1976. Joining the team as co-associate editor (with Steve Moore) under Rickard. He took over full editorial duties for the four quarterly issues of 1984-1985 (#43-46), to give Rickard a chance to "revitalize", (which he did). Sieveking then joined Rickard as co-editor for the next 16–17 years, until editorship was passed to David Sutton in 2002.
Sieveking is still a major part of FT, continuing as before to edit and write most of the Strange Days news section, to edit the letters pages, to act as quality-control proof-reader and contribute occasional feature articles.
Whilst an undergratuate at Cambridge, Sieveking co-edited with the artist Antony Gormley the little magazine Origo 3 (circa 1970, sole edition), which featured some of the artist's first published work. Sieveking has produced occasional articles for online magazine NthPosition, and is described by them as having "been a student of extreme human behaviour since the glory days of the Situationists."
