Maureen Duffy, author of more than 60 works and a pioneering activist for gay rights and writers’ rights, has died at the age of 92.

Duffy was awarded the inaugural £10,000 Royal Society of Literature (RSL) Pioneer prize last year by Bernardine Evaristo, who described her as a “true trailblazer in every sense of the word”.

She was an “extraordinary author” and a “tireless advocate for authors’ rights”, said Barbara Hayes, chief executive of the Authors’ Licensing and Collecting Society (ALCS), of which Duffy was a founding member. “For decades, she championed fair remuneration and proper recognition for creators with remarkable passion and conviction, leaving an enduring legacy for writers everywhere.”

Duffy, who died on Wednesday, wrote novels, plays, poetry and nonfiction, including The Microcosm, her landmark 1966 novel inspired by the Gateways lesbian club in London, and Restitution, which was longlisted for the Booker prize in 1998.

Born in Worthing, Sussex, in 1933, Duffy’s father left when she was a baby, and her mother died when she was 15. She won her first poetry competition aged 17, and studied English at King’s College London, graduating in 1956. The university would later inspire the Queen’s College London of her novel Capital, the second in her London trilogy. In the late 1950s, she taught in Naples and London while editing poetry journals.

In 1961, Granada Television commissioned her to write a screenplay, Josie, and she used the £450 advance to buy a houseboat. Her semi-autobiographical first novel, That’s How It Was, was published the following year, a bildungsroman following a girl, Paddy, whose father abandons her mother when she is born .

Alongside her novels, Duffy wrote for stage, screen and radio, as well as poetry collections and biographies, including a study of Aphra Behn, considered the first woman to earn a living by writing.

In the early 1960s, Duffy began campaigning for gay rights. In the 1970s, she often wrote for lesbian feminist journal Sappho, and in 1977, she published The Ballad of the Blasphemy Trial, a poem strongly condemning the infamous trial of the Gay News for blasphemous libel.

In 1972, Duffy co-founded the Writers’ Action Group, which led a campaign for a public lending right, ultimately made law in the late 70s, allowing authors to be paid each time their work is lent through libraries. This work led to the establishment of ALCS in 1977, aimed at ensuring authors are paid for secondary uses of their work.

“I’ve always been interested in politics and there’s a sort of bloody-mindedness in me that wants to take issues on,” Duffy said in 2017. “It’s a continuous battle. As well as authors’ rights, I’ve also been a campaigner for gay rights and animal rights. I feel very strongly that you have to stand up and play your part.”
