Wallace Wilfred Swinburne Breem was a British librarian and author. He served as the Librarian and Keeper of Manuscripts of the Inner Temple Law Library. Although he wrote non-fiction pieces, he is best known for his historical novels, particularly Eagle in the Snow (1970), which is considered a classic of English literature.

At the age of 18, Breem entered the Indian Army's Officers Training School, and in 1945, he was commissioned as an officer of the Corps of Guides, an elite Cavalry detachment of the North West Frontier Force. After the Partition of India in 1947, Breem returned to England, where he held various jobs, including working as a laborer in a tannery, assistant to a veterinary surgeon, and rent-collector in London's East End. He eventually joined the library staff of the Inner Temple in London in 1950.

He was a founding member of the British and Irish Association of Law Librarians (BIALL) and held positions such as secretary, treasurer, vice president, and president within the organization.
