Susan Cooper

In the 1970s two of the five novels were named the year's best English-language book with an "authentic Welsh background" by the Welsh Books Council. In 2024, the Science Fiction and Fantasy Writers Association named her the 40th Damon Knight Memorial Grand Master in recognition of her significant contributions to the literature of science fiction and fantasy.

Cooper was born in 1935 in Burnham, Buckinghamshire, to Ethel May (née Field) and her husband John Richard Cooper. Her father had worked in the reading room of the Natural History Museum until going off to fight in the Second World War, from which he returned with a wounded leg. He then pursued a career in the offices of the Great Western Railway. Her mother was a teacher of ten-year-olds and eventually became deputy head of a large school. Susan's younger brother Roderick also grew up to become a writer. Cooper lived in Buckinghamshire until she was 21, when her parents moved to her grandmother's village of Aberdyfi in Wales. She attended Slough High School and then earned a degree in English at Somerville College at the University of Oxford, where she was the first woman to edit the undergraduate newspaper Cherwell.

After graduating, she worked as a reporter for The Sunday Times (London) under Ian Fleming and wrote in her spare time. During that period she began work on the series The Dark Is Rising and finished her debut novel, the science fiction Mandrake, published by Hodder & Stoughton in 1964. Cooper emigrated to the United States in 1963 to marry Nicholas J. Grant, a professor of metallurgy at the Massachusetts Institute of Technology, and a widower with three teenage children. They had two children. Cooper then became a full-time writer, focusing on The Dark Is Rising and on Dawn of Fear (1970), a novel based on her experiences of the Second World War. Eventually she wrote fiction for both children and adults, a series of picture books, film screenplays, and works for the stage. Around the time of writing Seaward (1983), both of her parents died, and her marriage to Grant was dissolved. In July 1996, she married the Canadian-American actor and her sometime co-author Hume Cronyn, the widower of Jessica Tandy. (Cronyn and Tandy had starred in the Broadway production of Foxfire, written by Cooper and Cronyn and staged in 1982.) After Cronyn's death in 2003, she moved back to Massachusetts, building a house facing the North River in Marshfield, and also living in Cambridge. The history of the Marshfield area was the basis for her 2013 book Ghost Hawk, in which the spirit of a Wampanoag, whose people were decimated by European disease, witnesses the transformation of Massachusetts by the Plymouth Colony. She is a member of First Parish Unitarian Universalist Church of Scituate. Hollywood adapted The Dark Is Rising (1973) as a film in 2007, The Seeker. Before she saw the film, Cooper stated that she had requested some changes to it, but had received no response. From 2006 to 2012, Cooper was on the Board of the National Children's Book and Literacy Alliance (NCBLA), a US nonprofit organization that advocates for literacy, literature, and libraries. In April 2017, Cooper gave the fifth annual Tolkien Lecture at Pembroke College, Oxford, speaking on the role of fantasy literature in contemporary society. In 2019 she published The Shortest Day, based on her performance poem of the same title written for the Cambridge Christmas Revels in the 1970s.
