The cause of death was not immediately clear. Hackett had been suffering from a chest cold, though he had been in "robust good health" until a few days ago, according to a family spokesperson.
Hackett cut back professionally in 1996, after experiencing dizziness and shortness of breath onstage.
Increasingly reclusive, he nevertheless managed to keep telling jokes. Dick Martin, who with comedy partner Dan Rowan hosted the seminal TV series "Laugh-In," was among those who still received calls from Hackett regularly.
Hackett didn't identify himself, Martin told The Times on Monday. He just launched into the bit.
"About every afternoon he [called] with a joke," Martin said. "His mind was quite good. He had a few people he called. [Comedian] Louis Nye, I guess Jan Murray." Asked what sort of jokes Hackett told, Martin said, "It's like the old joke, 'Two guys and a duck walk into a bar.' He'd go from there. It made him feel very happy to make me laugh."

The show business bug stayed with him through a three-year stint in the Army, and Hackett spent the late 1940s and '50s as a comedian in cabarets and small clubs in New York, later expanding his reach as an entertainer by appearing on Broadway in the 1954 Sidney Kingsley musical farce "Lunatics and Lovers." The production was not well-received, one of a number of failed Broadway plays in which Hackett nevertheless received positive reviews.
In 1952, when Rowan and Martin made their debut at the Catskills' Concord Hotel, Hackett "was like a king there," Martin said. Hackett had come up in the Catskills as a tummler, a professional merrymaker. Soon he was ruling the Concord, the biggest of the resorts, which kept a suite for him year-round. It was there that he met his wife, the former Sherry Dubois.
The 1960s broadened the comedian's appeal, as Hackett increasingly indulged his own voice. He was soon on his way to becoming a beloved, if antic, raconteur — his stories increasingly woven into the fabric of his look and personality. The late
Over the decades, to be sure, Hackett's look helped make him inimitable: the rotund body with the cross-eyed gaze and the delivery in which he seemed to be talking out of the side of his mouth. His 1950s TV credits include his own sitcom, "Stanley," in which Hackett ran a newsstand in a swanky New York Hotel. The series, which co-starred
A year later, Hackett replaced
Like many other big-name nightclub comedians, Hackett made the transition to movies, but the results were hit and miss. Some said he was a
In 1962, Hackett gained more attention as a second fiddle, co-starring as Marcellus Washburn in "The Music Man," helping
But those who saw him live remember Hackett most vividly. He held court onstage from Atlantic City to Las Vegas, where he performed regularly for decades, most notably at the
A 1968 article in The Times reported that while making "The Love Bug," he was also flying to Vegas every Saturday and going onstage at the Sahara every Sunday, working from 3 a.m. to 5 a.m. He would then catch the 7:30 a.m. plane back to
Hackett was also a master on the dais of the Friars Club, where he was a member and a frequent — and potent — messenger of insults during the club's infamous celebrity roasts.
"Buddy was an innovator. In his time, he was the most creative comic that I've ever seen," said singer Steve Lawrence, who with Eydie Gorme traces his association with Hackett back to the New York of the 1950s.
Lawrence told The Times on Monday that, through his nightclub act, Hackett was "also a groundbreaker with a lot of taboos we grew up with. But he always did it in a way that was hysterical."
Hackett's edgy routines endeared him to a younger generation of comics who paid homage as though Hackett were their comedic godfather. Hackett, for instance, appeared in the 1999 Fox series "
In later years, as Hackett grew more reclusive, he battled more with weight troubles and other health problems. He was an avid gun collector but had sold off his collection, Martin said.
And after quitting the stage, the only time he performed was at the annual fund-raiser for the Singita Animal Sanctuary, a dog and cat rescue organization begun by Hackett and his wife.
Hackett is survived by his wife, Sherry; his son, Sandy; two daughters, Lisa and Ivy; and two grandchildren.
