Her agent, David Shaul, confirmed her death.
Ms. Stapleton, though never an ingénue or a leading lady, was an accomplished theater actress with a few television credits when the producer Norman Lear, who had seen her in the musical “Damn Yankees” on Broadway, asked her to audition for a new series. The audition, for a character named Edith Bunker, changed her life.
The show, initially called “Those Were the Days,” was Mr. Lear’s adaptation, for an American audience, of an English series called “Till Death Us Do Part,” about a working-class couple in east London who held reactionary and racist views.
It took shape slowly. The producers filmed three different pilots, the show changed networks to CBS from ABC, and Ms. Stapleton acted in a film directed by Mr. Lear, “Cold Turkey,” before “All in the Family,” as it was finally called, was first broadcast in January 1971.
For three or four months, hampered by mixed reviews, it struggled to find an audience, but when it did, it became one of the most popular shows in television, finishing first in the Nielsen ratings for five consecutive seasons and winning four consecutive Emmy Awards for outstanding comedy series. Ms. Stapleton won three Emmys of her own, in 1971, ’72 and ’78.
“All in the Family” was set in Queens. Most of the action took place in the well-worn but comfortable living room of the Bunker family, led by an irascible loading-dock worker named Archie whose attitudes toward anyone not exactly like him — that is, white, male, conservative and rabidly patriotic — were condescending, smug and demonstrably foolish. Memorably played by Carroll O’Connor, Archie bullied his wife, patronized his daughter, Gloria (Sally Struthers), and infuriated and was infuriated by his live-in son-in-law, a liberal student, Michael Stivic (Rob Reiner), whom he not-so-affectionately called Meathead.
Archie employed the vocabulary of a bigot and wielded the unenlightened opinions of a man from a bygone era who refused to admit the world was changing so much that it was no longer his naturally inherited domain.
But he was essentially harmless — small-minded but not meanspirited, ignorant but not unfeeling. Critics routinely referred to him as “a lovable bigot,” as if such a thing were possible. Edith loved him, certainly, though he referred to her, in her presence, as a dingbat and was perpetually telling her to shut up. “Stifle yourself,” was how he put it.
Edith was none too bright, not intellectually, anyway, which, in the dynamic of the show was the one thing about her that invited Archie’s outward scorn. Ms. Stapleton gave Edith a high-pitched nasal delivery, a frequently baffled expression and a hustling, servile gait that was almost a canter, especially when she was in a panic to get dinner on the table or to bring Archie a beer.
But in Edith, Ms. Stapleton also found vast wells of compassion and kindness, a natural delight in the company of other people, and a sense of fairness and justice that irritated her husband to no end and also put him to shame. She was an enormously appealing character, a favorite of audiences, who no doubt saw in the ordinariness of her life a bit of their own, and in her noble spirit a kind of inspiration.
Edith was not, like Ms. Moore’s Mary Richards, a spirited young professional seeking traction in a mostly male workplace, nor was she like Ms. Arthur’s Maude, a brassy, clamorously insistent personality.
