Louise Lynn Hay (October 8, 1926 – August 30, 2017) was an American motivational author and the founder of Hay House. She authored several New Thought self-help books, including the 1984 book, You Can Heal Your Life.
Born Helen Vera Lunney in Los Angeles to parents Henry John Lunney (1901–1998) and Veronica Chwala (1894–1985), Hay recounted her life story in an interview with Mark Oppenheimer of The New York Times in May 2008. In it, Hay stated that she was born in Los Angeles to a poor mother who remarried Louise's violent stepfather Ernest Carl Wanzenreid (1903-1992), who physically abused her and her mother. According to Hay, when she was about 5, she was raped by a neighbor. At 15, she dropped out of University High School in Los Angeles without a diploma, became pregnant and, on her 16th birthday, gave up her newborn baby girl for adoption. She then moved to Chicago, where she worked in low-paying jobs. In 1950, she moved on again, to New York. At this point she changed her first name, and began a career as a fashion model. She achieved success, working for Bill Blass, Oleg Cassini, and Pauline Trigère. In 1954, she married the English businessman Andrew Hay (1928-2001); after 14 years of marriage, she felt devastated when he left her for another woman, Sharman Douglas (1928-1996).
