Rosemary Timperley (20 March 1920 – 9 November 1988) was a British novelist, short story writer and screenwriter.
Born in Crouch End, North London on 20 March 1920 to architect George Kenyon Timperley and teacher Emily Mary (née Lethem), she went to Hornsey High School, before studying for a Bachelor of Arts degree in History at King's College London, graduating in 1941.
In the mid-1940s, while still working as a teacher, she started submitting short stories to magazines and newspapers, with the first, "Hot Air – and Penelope", being published in Illustrated 10 August 1946.
Still writing, she left her job as a teacher to become a staff writer for Reveille magazine in 1949, editing the personal advice column (under the pen name Jane Blythe), readers' letters and writing a number of stories, feature articles and book reviews.
By the early 1960s she had separated from her husband, who died in 1968, but she continued writing novels, short stories and scripts until her death on 9 November 1988.
