Margaret Hayes (1916(?) - January 26, 1977) was an American film and television actress.
Born December 5, 1916 (although the U.S. census for 1920 lists her as age 6) Florette Regina Ottenheimer in Baltimore, Maryland, she was often billed as Maggie Hayes in her film credits. She is perhaps best known for her role as Lois Judby Hammond in the film Blackboard Jungle (1955). Hayes played opposite Keith Andes in the role of Dorothy Maguire Grevemberg, wife of crusading Louisiana State Police superintendent Francis Grevemberg, in the film Damn Citizen (1958). Gene Evans also co-starred.
She married a Mr. Debusky in Baltimore, MD and had one child, Nan in 1937. She subsequently married actor Leif Erickson in 1942, but they divorced after a month. She married a third time, to producer Herbert B. Swope, Jr., in 1947 and she had a daughter, Tracy Brooks Swope, who is also an actress. She and Swope divorced in 1973.
Margaret Hayes died at the age of 60 in Miami Beach, Florida, from liver cancer and hepatitis.
