John Clute was born in 1940 in Toronto, Canada, but has lived and worked in London since 1969. He began writing SF reviews and criticism in the early 1960s; the eighth volume collecting this work is Sticking to the End (2020). As co-editor and now main contributor, he has been involved in The Encyclopedia of Science Fiction since its first print edition in 1979; the online version, eight times the length of the original, continues to expand. His second novel, Appleseed (2001), is SF. He has won various awards, including several Hugos, for his work. The 12,000 volume Clute Library of Science Fiction is now owned and curated by the Telluride Institute in Telluride, Colorado.
