Kathleen Fidler was born in Coalville, Leicestershire in 1890, and was raised in Wigan and North Wales, where he became a teacher and later school headmistress. She married in 1930 and moved to Edinburgh shortly afterwards, where she began writing stories for her children. She finally settled in Lasswade in Midlothian. Over the course of her career, she wrote over 80 novels and non-fiction books for children. Many of her novels followed the adventures of two families, The Brydons and The Deans. Her work has been praised for the depth and detail of research into the background of her stories.
After Fidler died in 1980, her publishers and members of the Edinburgh Children’s Book Group established the Kathleen Fidler Award in memory of her work and support for children’s literature. The award, which closed in 2002, was awarded to previously unpublished authors for novels for children aged 8 to 12.
