Marijane Meaker, the pioneering and prolific author who wrote dozens of books under a variety of pen names, has died at 95, the New York Times reports.

Meaker grew up in Auburn, New York, and was educated at Vermont Junior College and the University of Missouri. She published her first two mystery novels, Dark Intruder and Spring Fire, in 1952, under the name Vin Packer; the latter is considered one of the first significant works of lesbian pulp fiction and was a massive bestseller.

She wrote nonfiction books under the name Ann Aldrich, including We, Too, Must Love and Take a Lesbian to Lunch, and published a handful of books with her own name.

Meaker was perhaps best known from the 1970s onward for the young adult novels she wrote as M.E. Kerr, including Dinky Hocker Shoots Smack!, Deliver Us From Evie, What Became of Her, and Someone Like Summer. She also wrote children’s books, such as The Shuteyes and Shoebag Returns, as Mary James.

In 1993, Meaker won the prestigious American Library Association Margaret Edwards Award, given annually to a writer of young adult literature.

Meaker was remembered by her admirers on social media. On Twitter, author Sarah Weinman wrote, “Devoured her M.E. Kerr books as a kid/teen, admired her pulp noirs as Vin Packer, and of course, SPRING FIRE basically created the lesbian fiction category. Farewell to Marijane Meaker, a giant of so many genres.”

And writer Sarah Schulman tweeted, “RIP Marijane Meaker aka Vin Packer aka Ann Aldridge. She did what she had to do to get lesbian stories into the world.”
