Milford began life as an annual science fiction and fantasy writers’ get-together in the USA in 1956 under the auspices of Damon Knight. In 1972 James and Judy Blish moved to the UK and brought Milford with them, styling it a conference and holding annual events (originally) in Milford-on-Sea.
Milford’s conference has moved several times since then, being held in Cheltenham, Margate, Rothbury, Maidencombe, York and now in North Wales, in the tiny village of Nantlle at Trigonos.
In 1972 Milford attendees included the Blishes, Anne McCaffrey and Brian Aldiss amongst others. Writers who have passed through Milford since then include: Alastair Reynolds; Charles Stross; Chris Priest; David Langford; Diana Wynne Jones; Geoff Ryman; George R.R. Martin; Jaine Fenn; John Clute; Karen Traviss; Liz Williams; Mary Gentle; Patricia Wrede; Neil Gaiman, and many, many more.
Milford runs as a not-for-profit organisation with an elected (unpaid) committee. It is not a membership organisation as such, but all writers who have attended are kept up to date about Milford happenings through a private mailing list.
