Lynn Fontanne (6 December 1887 – 30 July 1983) was a British actress and major stage star in the United States for over 40 years, who with her husband Alfred Lunt was part of the most acclaimed acting team in the history of the American theater.

Despite living in the U.S. for over 60 years, she never relinquished her British citizenship. She and her husband shared a special Tony Award in 1970. She also won an Emmy award in 1965, and was a Kennedy Center honoree very late in life.

Born Lillie Louise Fontanne in Woodford, United Kingdom, Fontanne first drew popular acclaim in 1921 playing the cliché-spouting title role in the George S. Kaufman-Marc Connelly`s farce Dulcy. Dorothy Parker memorialized her performance in verse:

Dulcy, take our gratitude, / All your words are golden ones. / Mistress of the platitude, / Queen of all the old ones. / You, at last, are something new / ’Neath the theatre’s dome. I’d / Mention to the cosmos, you / Swing a wicked bromide. ...

She soon became celebrated for her skill as an actress in high comedy, excelling in witty roles written for her by Noël Coward, S. N. Behrman and Robert Sherwood. Fontanne`s flair for elegant romantic comedy is often credited with creating a new style of dramatic heroine and an inspiration and influence on later screen actresses like Claudette Colbert, Myrna Loy, and Carole Lombard who brought the rhythm to their screen performances.

By contrast, Fontanne enjoyed one of the greatest critical successes of her career as Nina Leeds, the desperate heroine of Eugene O`Neill`s nine-act drama, Strange Interlude.

From the late 1920s on, Fontanne acted exclusively in vehicles also starring her husband. Among their greatest theater triumphs were Design for Living (1933), The Taming of the Shrew (1935-1936), Idiot`s Delight (1936), There Shall Be No Night (1940), and Quadrille (1952). The Lunts remained highly active on the stage until retiring in 1960. Fontanne was nominated for a Best Actress Tony for one of her last stage roles, in The Visit (1959).

Fontanne made only three movies, but nevertheless, was nominated for the Academy Award for Best Actress in 1931 for The Guardsman, losing to the much younger Helen Hayes. She also appeared in the silent movies Second Youth (1924) and The Man Who Found Himself (1925).

The Lunts starred in four television productions in the 1950s and 1960s with both Lunt and Fontanne winning an Emmy award in 1965 for The Magnificent Yankee, becoming the first married couple to win the award for playing a married couple. She also narrated the classic 1960 television production of Peter Pan starring Mary Martin and received a second Emmy nomination for playing Grand Duchess Marie in the Hallmark Hall of Fame telecast of Anastasia in 1967, both rare performances that she did without her husband.

The Lunts also starred in several radio dramas in the 1940s, notably on the Theatre Guild program. Many of these broadcasts still survive.

Fontanne`s romance with Lunt began in 1920 while he was starring in the play Clarence with Helen Hayes, who had discreetly fallen in love with him. The Lunts were married in 1922. Hayes remained a lifelong friend of the pair, although many believe she never quite forgave Fontanne for "stealing" Lunt from her. Hayes` 1988 autobiography, published after the Lunts` deaths, contains several barbs directed at Fontanne, who supposedly was her friend for decades.
