Peg Yorkin, a feminist activist and philanthropist who as a founding father of the Feminist Majority, a nationwide girls’s rights group, campaigned to deliver mifepristone, the abortion capsule, to the United States and to extend the variety of girls in political workplace, died on Sunday at her house in Malibu, Calif. She was 96.

The trigger was renal failure, stated her daughter, Nicole Yorkin.

The Feminist Majority was based in 1987 by Ms. Yorkin, Katherine Spillar, Toni Carabillo, Judith Meuli and Eleanor Smeal, a former president of the National Organization for Women. They took the group’s title from polling indicating that greater than 50 p.c of girls within the U.S. recognized as feminists.

The group’s first push was to extend the variety of girls working for workplace; on the time, solely 5 p.c of the members of Congress had been feminine. To provoke girls, Ms. Yorkin produced a multistate tour by 21 cities that she designed like a political conference; on the finish of every occasion, there was what Ms. Smeal characterised in a telephone interview as an “altar call,” with some girls pledging to run for workplace and others pledging to help them.

Within 5 years, the variety of girls in Congress doubled (it is now 28 percent). Ms. Yorkin was so dogged in her efforts and so beneficiant together with her monetary help, Ms. Smeal stated, that Barbara Mikulski, the longtime Democratic senator from Maryland, as soon as described her as a one-woman political motion committee.

Ms. Yorkin and her colleagues subsequent turned to mifepristone, which the French authorities in 1998 had authorised to be used in household planning facilities to induce abortions within the early levels of being pregnant. (Claude Évin, the French well being minister, declared the drug “the moral property of women.”) But it will take 12 years for its use to be authorised within the United States.

Ms. Yorkin, Ms. Smeal and others gathered help from scientists and politicians, and in 1990 they traveled to Europe to induce the French firm that had the patent for mifepristone to hunt Food and Drug Administration approval — whereas, on the identical time, anti-abortion activists had been preventing to maintain it out. The subsequent yr, Ms. Yorkin gave $10 million to her group to supercharge its efforts. It was believed to be the biggest present so far to a girls’s rights group.

Women must “put our money where our anger is,” Ms. Yorkin told The Los Angeles Times in 1991, including that, “it is time to stop begging men for our rights” and to “turn our rage into direct action.”

For a long time, Ms. Yorkin had been a “Hollywood wife” recognized for her charitable work. She was married to Bud Yorkin, the tv producer who with Norman Lear created “All in the Family,” the pioneering sitcom centered on a working-class bigot named Archie Bunker that upended tv in 1971, and its celebrated spinoffs “Maude” and “The Jeffersons,” in addition to different hit exhibits like “Sanford and Son.”

In 1973, The New York Times called Ms. Yorkin the “queen of Hollywood society,” noting her work as president of SHARE Inc. (the initials stand for Share Happily and Reap Endlessly), a Beverly Hills charity that advantages youngsters with disabilities. She typically described herself as a typical ’50s housewife — a product of her time who, like many ladies, was emboldened by second-wave feminism.

In the ’70s, she threw herself into the ladies’s motion, pushing for the ratification of the Equal Rights Amendment amongst different efforts. After she left SHARE, she went on to run the Los Angeles Shakespeare Festival after which the L.A. Public Theater, producing work by playwrights like A.R. Gurney and John Guare. But it was solely after her divorce from Mr. Yorkin in 1986, when Ms. Yorkin was 60, that she was in a position to totally deal with the work that may deliver her nationwide consideration.

“It wasn’t until a 30-year marriage had gone bust and I reaped the benefits of the California community-property laws that I was able to do something concrete about feminism,” she said in an interview for her entry within the 1999 e book “Women in World History: A Biographical Encyclopedia.”

Ms. Spillar, who’s now government director of the Feminist Majority, remembered Ms. Yorkin saying that within the days earlier than the landmark Roe v. Wade ruling, she helped girls discover docs in Mexico who might present abortions. She stated, Ms. Spillar recalled: “I want us to think big and I want us to do more and I want us to hurry up. I’m not going to live forever and I want this done in my lifetime.”

Peggy Diem was born on April 16, 1927, in New York City. (She loathed her given title and glided by Margaret in highschool after which by Peg.) Her mom, Dora (Lavine) Diem, was a homemaker who had needed to be an actress. Her father, Frank, was a nonetheless photographer who labored for D.W. Griffith and different filmmakers.

Frank, an alcoholic, left the household when Peg was 11; Dora struggled financially and moved in together with her mom in Yonkers, N.Y., with whom younger Peg shared a mattress. It was, she would later recall, a traumatic childhood.

Peg was extraordinarily brilliant and skipped just a few grades at Roosevelt High School earlier than being admitted to Barnard College at 16 on a scholarship. But, pressured by her mom, she left after two years to pursue an performing profession she didn’t need. A quick marriage to Newt Arnold, a movie director, led to divorce when he instructed her he was having an affair, however it introduced her to Los Angeles and away from her mom. She married Mr. Yorkin, whom she had met in an agent’s workplace, in 1954.

“If I’d been a man I would have been extremely successful in business,” she instructed The Los Angeles Times in 1991. “I could have been Bud Yorkin if I were a man.”

Still, she discovered her personal means. To assist finance her theater productions within the late Nineteen Seventies and early ’80s, she ran a bingo sport yearly on the night time of the Academy Awards ceremony. “The gamblers don’t care about the Academy Awards,” her son recalled her saying, although she used saltier language. A bronze plaque on the door of her workplace learn: “Peg Yorkin Is Beyond Therapy. Do Not Disturb.”

In 2001, she gave one other $5 million to her group to assist it purchase Ms. journal, which was based by Gloria Steinem and others in 1971 and had been struggling for a while. “We were not a media company, but we were determined not to lose a feminist press and Gloria asked us for help,” Ms. Smeal stated. “And Peg said, ‘We don’t have a choice. If Gloria says we gotta do it, we gotta do it.’”

In addition to her daughter, Ms. Yorkin is survived by a son, David, and 4 grandchildren.

Since the F.D.A. authorised mifepristone in 2000, greater than 5 million girls have used it to finish their pregnancies; it now accounts for more than 50 percent of all abortions. But after the Supreme Court overturned Roe v. Wade in 2022, ending a lady’s assured proper to abortion, anti-abortion activists started to deal with entry to mifepristone. In April, a decide in Texas suspended the F.D.A.’s decades-old approval of the drug, a ruling that has the potential to take it off the market nationwide. The Supreme Court has halted the ruling for now.

Looking again on the 12-year effort to deliver mifepristone to the United States, Ms. Smeal recalled Ms. Yorkin’s insistence that the Feminist Majority keep the course. “She said it had to be done and it would save lives and we could not get discouraged,” she stated, including, “You can’t be summer soldiers in feminism.”
