Madeleine Carroll (February 26, 1906 - October 2, 1987) was a British actress, immensely popular in the 1930s and 1940s, who was renowned for her great beauty.

She was born as Edith Madeleine Carroll at 32 Herbert Street (now number 44) West Bromwich, England. She graduated from the University of Birmingham, England.

Widely recognized as one of the most beautiful women in films, Carroll's aristocratic blonde allure and sophisticated style were first glimpsed by British movie audiences in The Guns of Loos in 1928. Rapidly rising to stardom in England, she graced such popular films of the early '30s as Young Woodley, Atlantic (1929 film) The School for Scandal and I Was A Spy. Abruptly, she announced plans to retire from films to devote herself to a private life with her husband, the first of four.

She attracted the attention of Alfred Hitchcock and, in 1935, starred as one of the director's earliest prototypical cool, glib, intelligent blondes in The 39 Steps based on the seminal espionage novel by John Buchan. The film became a sensation and with it, so did Carroll. Cited by the New York Times for a performance that was "charming and skillful," Carroll became very much in demand thanks, in part, to director Hitchcock, who later admitted that he worked very hard with her to bring out the vivacious and sexy qualities she possessed offscreen, but which sometimes vanished when cameras rolled. Of Hitchcock's heroines, as exemplified by Carroll, film critic Roger Ebert once wrote that they "reflected the same qualities over and over again: They were blonde. They were icy and remote. They were imprisoned in costumes that subtly combined fashion with fetishism. They mesmerized the men, who often had physical or psychological handicaps."

The director wanted to re-team Carroll with her 39 Steps co-star Robert Donat the following year in Secret Agent, a spy thriller based on a work by W. Somerset Maugham. However, Donat's recurring health problems prevented him from accepting the role and, instead, Hitchcock paired Carroll with John Gielgud.

Poised for international stardom, Carroll was the first British beauty to be offered a major American film contract; she accepted a lucrative deal with Paramount Pictures. She starred opposite Gary Cooper in the adventure The General Died at Dawn and with Ronald Colman in the 1937 box-office hit The Prisoner of Zenda. She tried a big musical On The Avenue (1937) opposite Dick Powell, but others of her films, including One Night in Lisbon (1941), and My Favorite Blonde (1942) with Bob Hope, were less prestigious. She made her final film for director Otto Preminger, The Fan, adapted from Oscar Wilde's Lady Windermere's Fan, in 1949.

For her contribution to the motion picture industry, Madeleine Carroll has a star on the Hollywood Walk of Fame at 6707 Hollywood Blvd. A commemorative monument and plaques were unveiled in her birthplace, West Bromwich, to mark the centenary of her birth.

She appeared on the NBC Radio program, "Chase and Sanborn Hour" October 30, 1938, with Nelson Eddy and Dorothy Lamour (vocalists), Robert Armbruster and his orchestra, starring Edgar Bergen (Charlie McCarthy), Don Ameche (host), Judy Zeke and Anne Canova. She performed with Nelson Eddy, Don Ameche and Edgar Bergen.

After her sister Marguerite was killed in a London bombing raid, she halted her acting career and worked in field hospitals as a Red Cross nurse. She was given the Legion d'Honneur for bravery in France.

She studied at Birmingham University (UK). Her father wanted her to be a French teacher, but she defied him and became an actress.

She was the first of Alfred Hitchcock's "ice-cool blondes", and was the highest-paid Hollywood actress of her time.
