Pathology of Lying, Accusation, and Swindling: A Study in Forensic Psychology
by William Healy, Mary Tenney Healy
About the author
Mary Tenney Healy was an American writer and psychology collaborator best known for Pathological Lying, Accusation, and Swindling: A Study in Forensic Psychology, published in 1915 with William Healy. The book became one of the better-known early works exploring chronic lying, false charges, and related behavior through detailed case studies.
Available records about her are limited, but she is associated with reform-minded and psychological circles of her time, and later listings of her work continued to credit her as co-author rather than a silent assistant. She appears in library records under her own name, which suggests a recognized role in the research and writing behind the book.
She was born in Madison, Wisconsin, in 1865 and died in Boston in 1932. Even with few biographical details surviving, her name remains attached to an influential early contribution to forensic psychology and the study of abnormal behavior.
