Emily Elizabeth Dickinson was born in Amherst, Massachusetts, on December 10, 1830 to Edward Dickinson (AC 1823) and Emily Norcross Dickinson. She attended Amherst Academy from 1840 to 1847, then enrolled at Mount Holyoke Female Seminary from 1847 to 1848. She remained in Amherst for the rest of her life, and traveled only briefly to Boston, Philadelphia and Washington, D.C.

For virtually her entire adult life, Emily lived in the Dickinson home at 280 Main Street with her father, mother, and her younger sister, Lavinia, who Emily called "Vinnie." Her brother, (William) Austin (AC 1850) lived next door with his wife, Susan Huntington Gilbert, one of Emily's closest friends. Emily was very close to their three children, Ned (Edward) (AC 1884), Mattie (Martha), and Gib (Thomas Gilbert). After the death of her father in 1874 and her mother the following year, Emily remained in the family home, living alone with Vinnie. Emily died there on May 15, 1886, at the age of 55. Renowned for a severe reclusiveness that began when she was in her 20s, Dickinson maintained warm and close relationships with family and friends through the medium of letters, frequently containing poems. Some of her most frequent correspondents outside of her family were childhood friends Abiah Root and Emily Fowler (Ford); her friend and later sister-in-law, Susan Huntington Gilbert (Dickinson); Samuel Bowles, editor of the ; Reverend Charles Wadsworth, a minister and poet; Thomas Wentworth Higginson, writer and liberal activist; Josiah Gilbert and Elizabeth Chapin Holland; and Adelaide Spencer (Mrs. Henry) Hills. A significant correspondent around 1858-1861 was a mysterious love interest who Dickinson referred to as "Master." It is not clear who this person may have been or what form any relationship between them took - only three draft letters by Dickinson to "Master" are known. Another important person Dickinson's life was Judge Otis Phillips Lord, with whom Dickinson had a romantic relationship starting in the late 1870s until his death in 1884.

Although Emily and Lavinia were very close, and Lavinia was aware that Emily wrote poetry, she was not aware of the extent of her sister's writing. Upon Emily's death, Lavinia discovered how prolific and talented her sister had been when she found 1,775 poems in Emily's bureau drawer. Emily wrote some 1,789 poems, some contained in letters to friends and family, some sewn together in little bundles called fascicles that Emily stored in her drawers, some written on scraps of paper like shopping lists or envelope flaps. Lavinia preserved the poems she found, distributing them between Mabel Loomis Todd and Susan Dickinson, but destroyed all of Emily's correspondence in accord with her sister's previously expressed wishes.

Within 10 years of Emily's death, three volumes of her poetry and two volumes of her letters were published by Thomas Wentworth Higginson and Mabel Loomis Todd, a woman with whom Austin had a long-term affair during his marriage to Susan. Emily Dickinson's niece, Martha Dickinson Bianchi (Austin's daughter), also helped to publish her aunt's poetry beginning in 1914.

It was not until 1955, when Harvard published edited by Thomas Johnson, that all of Dickinson's poetry was available in a single source. In 1960, Jay Leyda published , a chronological documentation of the events in the lives of Emily Dickinson and her family and friends. In 1998, Ralph W. Franklin, published , which documents revisions and different versions of the poet's work.

Unknown during her lifetime, Emily Dickinson is known today as one of the world's most important and loved poets of all-time, in any language.
