In short: Long before science fiction became a household genre, Margaret Cavendish was writing utopian romances and engaging with the era's greatest scientific minds. A prolific author who defied the gender norms of the 1600s, she navigated a world of exile and royal courts while relentlessly pursuing recognition as a serious philosopher.

Born in 1623, Margaret Cavendish was an English natural philosopher, poet, and playwright who published over a dozen original works at a time when women were largely excluded from the literary sphere. Her utopian romance, The Blazing World, is recognized as one of the earliest examples of science fiction. Beyond fiction, she was a serious intellectual who engaged with influential thinkers like René Descartes, Thomas Hobbes, and Robert Boyle. In May 1667, she made history as the first woman to attend a meeting of the Royal Society of London.

Cavendish’s life was defined by the political turmoil of the 17th century. As a royalist, she spent years in exile in France with her husband, William Cavendish, the 1st Duke of Newcastle-upon-Tyne, whom she married in 1645. During this period, she produced a vast body of work, often including her portrait on book covers to ensure readers knew she was the sole creator of her texts. She frequently used prefaces and epistles to justify her writing, navigating the tension between her desire for fame and the societal expectation that women remain anonymous and domestic.

Her philosophical views were equally bold. She rejected the mechanical philosophy and Aristotelianism of her time, favoring a vitalist model instead. While she acknowledged the existence of God, she sought to separate philosophy from theology, arguing that natural reason could not fully grasp an immaterial being. Despite her lack of formal education, she was a prolific writer who used her platform to advocate for women's education, arguing that women were inherently capable of learning. She died in 1673 and was buried in Westminster Abbey, leaving behind a legacy as a ground-breaking, if often controversial, intellectual figure.

Cavendish was acutely aware of her unique position, often using her writing to satirize her own 'melancholia' and bashfulness. She viewed her books as extensions of herself—sometimes comparing them to children—and was unapologetic in her quest for everlasting fame. By documenting her own life in her 1656 memoir, she aimed to control her narrative for future generations, effectively challenging the contemporary belief that women were intellectually inferior to men.
