Margaret Cavendish, Duchess of Newcastle-upon-Tyne, was a renowned English philosopher, poet, scientist, fiction writer, and playwright. Cavendish’s prolific contributions included six published books on natural philosophy, although she was not truly appreciated during her lifetime.
In an era when it was seen as inappropriate for a woman to be publically intellectual, she could study in private and converse with two trusted men – her brother John and her husband William, both philosophers and scholars.
Even for a person with substantial wealth and connections, she struggled to be taken seriously by publishers or philosophers of the time.
In her time, opinions about her varied widely, from eccentric, mad, and pretentious to fascinating and genius. Her long-awaited recognition came in 1667 with an invitation to the Royal Society, though she still remained an unusual spectacle to many in attendance.
Throughout her life, she produced several important works in philosophy. These include Worlds Olio (1655), Philosophical and Physical Opinions (1656), Philosophical Letters (1664), Observations Upon Experimental Philosophy (1666), The Description of a New World, Called the Blazing World (1666), and Grounds of Natural Philosophy (1668).
The Blazing World is a work of fiction forerunner of science-fiction and could be considered a utopian story. In her books, women are portrayed as capable and discuss matters of Nature with many – something Cavendish was denied in her own life. She is often considered a protofeminist, expressing wishes for women to control their lives and finances and be respected for their abilities.
From Famous Women: An Outline of Feminine Achievement Through the Ages With Life Stories of Five Hundred Noted Women. Written by Joseph Adelman, published 1926 by Ellis M Lonow Company:
Margaret Cavendish, Duchess of Newcastle, an English writer. She became maid of honor to Queen Henrietta Maria in 1863, and two years later married William Cavendish, afterward Duke of Newcastle.
Her writings, consisting of plays, poems, sketches, letters, an autobiography, and a memoir of her husband, are very interesting.
She died in London and was buried in Westminster Abbey. The famous inscription on her tomb declares that she belonged to a family of which “all the brothers were valiant and all the sisters virtuous.”
