Emma Lazarus (July 22, 1849 – November 19, 1887) was an American author of poetry, prose, and translations, as well as an activist for Jewish and Georgist causes. She is remembered for writing the sonnet "The New Colossus", which was inspired by the Statue of Liberty, in 1883. Its lines appear inscribed on a bronze plaque, installed in 1903, on the pedestal of the Statue of Liberty. Lazarus was involved in aiding refugees to New York who had fled antisemitic pogroms in eastern Europe, and she saw a way to express her empathy for these refugees in terms of the statue. The last lines of the sonnet were set to music by Irving Berlin as the song "Give Me Your Tired, Your Poor" for the 1949 musical Miss Liberty, which was based on the sculpting of the Statue of Liberty (Liberty Enlightening the World). The latter part of the sonnet was also set by Lee Hoiby in his song "The Lady of the Harbor" written in 1985 as part of his song cycle "Three Women".

Lazarus was also the author of Poems and Translations (New York, 1867); Admetus, and other Poems (1871); Alide: An Episode of Goethe's Life (Philadelphia, 1874); Poems and Ballads of Heine (New York, 1881); Poems, 2 Vols.; Narrative, Lyric and Dramatic; as well as Jewish Poems and Translations.

Emma Lazarus was born in New York City, July 22, 1849, into a large Jewish family. She was the fourth of seven children of Moses Lazarus, a wealthy merchant and sugar refiner, and Esther Nathan (of a long-established German-Jewish New York family). One of her great-grandfathers on the Lazarus side was from Germany; the rest of her Lazarus ancestors were originally from Portugal and they were among the original twenty-three Portuguese Jews who arrived in New Amsterdam after they fled Recife, Brazil, in an attempt to flee from the Inquisition. Lazarus's great-great-grandmother on her mother's side, Grace Seixas Nathan (born in Stratford, Connecticut, in 1752) was also a poet. Lazarus was related through her mother to Benjamin N. Cardozo, Associate Justice of the Supreme Court of the United States. Her siblings included sisters Josephine, Sarah, Mary, Agnes and Annie, and a brother, Frank.

Privately educated by tutors from an early age, she studied American and British literature as well as several languages, including German, French, and Italian. She was attracted in youth to poetry, writing her first lyrics when she was eleven years old.

The first stimulus for Lazarus's writing was offered by the American Civil War. A collection of her Poems and Translations, verses written between the ages of fourteen and seventeen, appeared in 1867 (New York), and was commended by William Cullen Bryant. It included translations from Friedrich Schiller, Heinrich Heine, Alexandre Dumas, and Victor Hugo. Admetus and Other Poems followed in 1871. The title poem was dedicated "To my friend Ralph Waldo Emerson", whose works and personality were exercising an abiding influence upon the poet's intellectual growth. During the next decade, in which "Phantasies" and "Epochs" were written, her poems appeared chiefly in Lippincott's Monthly Magazine and Scribner's Monthly.

By this time, Lazarus's work had won recognition abroad. Her first prose production, Alide: An Episode of Goethe's Life, a romance treating of the Friederike Brion incident, was published in 1874 (Philadelphia), and was followed by The Spagnoletto (1876), a tragedy. Poems and Ballads of Heinrich Heine (New York, 1881) followed, and was prefixed by a biographical sketch of Heine; Lazarus's renderings of some of Heine's verse are considered among the best in English. In the same year, 1881, she became friends with Rose Hawthorne Lathrop. In April 1882, Lazarus published in The Century Magazine the article "Was the Earl of Beaconsfield a Representative Jew?" Her statement of the reasons for answering this question in the affirmative may be taken to close what may be termed the Hellenic and journeyman period of Lazarus's life, during which her subjects were drawn from classic and romantic sources.

Lazarus also wrote The Crowing of the Red Cock, and the sixteen-part cycle poem "Epochs". In addition to writing her own poems, Lazarus edited many adaptations of German poems, notably those of Johann Wolfgang von Goethe and Heinrich Heine. She also wrote a novel and two plays in five acts, The Spagnoletto, a tragic verse drama about the titular figure and The Dance to Death, a dramatization of a German short story about the burning of Jews in Nordhausen during the Black Death. During the time Lazarus became interested in her Jewish roots, she continued her purely literary and critical work in magazines with such articles as "Tommaso Salvini", "Salvini's 'King Lear'", "Emerson's Personality", "Heine, the Poet", "A Day in Surrey with William Morris", and others.

Not like the brazen giant of Greek fame,
With conquering limbs astride from land to land;
Here at our sea-washed, sunset gates shall stand
A mighty woman with a torch, whose flame
Is the imprisoned lightning, and her name
Mother of Exiles. From her beacon-hand
Glows world-wide welcome; her mild eyes command
The air-bridged harbor that twin cities frame.
"Keep, ancient lands, your storied pomp!" cries she
With silent lips. "Give me your tired, your poor,
Your huddled masses yearning to breathe free,
The wretched refuse of your teeming shore.
Send these, the homeless, tempest-tost to me,
I lift my lamp beside the golden door!" (1883)
