LOS ANGELES

While Jane Austen admirers savor the wit and romance of “Pride and Prejudice” and her other enduring novels, scholars ferret out details of Austen’s life and times, including a family link to slavery that surfaced 50 years ago.

The effort to place the writer in the social and political context of her day has yielded a new and contrasting discovery: A favorite brother was part of the 19th-century abolition movement.

Devoney Looser, an Arizona State University professor and author of “The Making of Jane Austen,” unearthed the Rev. Henry Thomas Austen’s attendance at the 1840 World Anti-Slavery Convention in London, which drew some 500 delegates.

“I was stunned to find that fact,” Looser said in an interview. She first detailed her research in an essay for The Times Literary Supplement.

“The family’s commitments and actions changed profoundly, from known complicity in colonial slavery to previously unnoticed anti-slavery activism,” Looser wrote. “Henry became a next-generation Austen publicly supporting a political commitment to abolish slavery across the globe.”

Looser’s essay also addresses patriarch George Austen’s previously revealed ties to another family’s West Indian sugar plantation, calling them “very real” but “both under-described and overstated.”

The latest research was welcomed by Patricia A. Matthew, an associate professor of English at Montclair State University who focuses on literature of the period that encompasses Austen. Her courses include British abolitionist literature.

“I’m always excited about new information about the authors I teach,” Matthew said. While it doesn’t change her view of Austen’s work — “I don’t believe that I’m reading someone who’s actively engaged in debates about the slave trade” — it could resound with Austen’s most devoted admirers, sometimes called “Janeites.”

“I think they are having a kind of reckoning in how they think about not just Austen, but the Regency period,” said Matthew, referring to the British era of the early 1800s. “It raises all manner of interesting questions about how they understand this author.”

The six major novels that Jane Austen wrote before her death at 41 in July 1817 are sharply observed works about human nature and relationships, not anchored in current events. There is a reference to slavery in “Mansfield Park,” and a conversation between two characters in “Emma” includes mentions of abolition and the sale of “human flesh.”

As for Austen’s own beliefs, Looser said, “we know from her letters that she refers to having loved the writings of a prominent white abolitionist, Thomas Clarkson. So we know that she read and cared about issues of race and racial injustice.”
