Margaret Cavendish

-
Margaret Cavendish, who was by marriage a great lady, wrote in the seventeenth century primarily to please herself and her husband, who was an enthusiast for her writing; they took pleasure in her publishing as well as her writing. Her works (scientific speculations, poems, plays, speeches, biography and autobiography) were issued in handsome folio volumes, with her name and some honorific description, primarily for presentation more than for sale. Two women printers published works by her.

Biography

She consistently signed her name (at least in print) Margaret Newcastle. This would seem the most logical, consistent, and respectful way of naming her, and she was called Duchess of Newcastle for many generations (though her title only changed from Marchioness in March 1665). But now that feminist literary history knows her as Margaret Cavendish, this has become the inevitable form of her name.
