Mabel Loomis Todd

Mabel Loomis Todd or Mabel Loomis (November 10, 1856 – October 14, 1932) was an American editor and writer. She is remembered as the editor of posthumously published editions of Emily Dickinson's poetry and letters and also wrote several novels and books about her travels with her husband, astronomer David Peck Todd, as well as co-authoring a textbook on astronomy.

Todd's relationship to the Dickinson family was complicated. She had a lengthy affair with Emily's married older brother William Austin Dickinson. In preparing Emily's poetry for publication, which was also marred by family controversies, "she and co-editor Thomas Wentworth Higginson altered words, changed Dickinson’s punctuation, capitalization and syntax to make her poetry closer to the conventions of 19th century verse. Perhaps most controversially, they gave names to poems that originally bore none (of Dickinson’s close to 2000 known poems, perhaps only a dozen were given names by the poet, herself)."
