Kathleen Fidler was born in Leicestershire, England and raised in Wigan and in North Wales. She became a school teacher and later a headmistress. In 1930, she married James Goldie and moved to Scotland. She began writing stories for her own children, and became a highly prolific author who published more than 80 novels and nonfiction titles. Many of her novels followed the adventures of two families, The Brydons and The Deans. After her death in 1980, her publishers and members of the Edinburgh Children's Book Group established the Kathleen Fidler Award for previously unpublished authors of novels for children aged 8 to 12.
