Her family, which continues to operate the theater, announced her death in a statement but did not give a cause.

Ms. Bouglione, known as Madame Rosa, was one of the last links to an era in which clowns, acrobats, lion tamers, trapeze artists, jugglers and other circus performers were a source of international renown and national pride — considered “artists,” as the New York Times once put it, in a 1950 dispatch on the Paris circus scene, “to be judged as critically as any other virtuosi.”

At the Cirque d’Hiver, which her husband, Joseph, acquired with his three brothers in 1934, Ms. Bouglione helped oversee nautical shows, acrobatic performances, operettas, ballets and pantomime productions such as “The Idol of Shanghai” and “The Adventures of the Princess of Sheba.” She and her husband, an animal trainer she likened to a Gallic cowboy, both came from Roma (sometimes known as gypsy) circus families, and they went on to lead Bouglione circus acts on tours across Europe, Africa, Asia and South America.

Their audiences regularly numbered into the thousands and included entertainers such as Marlene Dietrich, Ingrid Bergman and Josephine Baker, who gave Ms. Bouglione costume suggestions, as well as French politicians including Vincent Auriol and Georges Pompidou. Maria Callas, the famed opera singer, was once nearly flattened by a “jealous” elephant, Ms. Bouglione said, when she came too close to Joseph Bouglione after a show.

While Ms. Bouglione came to spend most of her time as an offstage ring master, she was a regular presence in European newspapers and magazines, a circus matriarch whose high-wire career survived the Nazi occupation of Paris and the occasional animal mishap, including when a herd of elephants escaped while her circus was on tour.

On a flight from Saigon to Paris, the New York Herald Tribune reported in 1948, a panther came loose in the plane’s baggage compartment, “either because its cage was insufficiently firm or because a press agent for the Bouglione Circus thought it would be a good idea.” The panther was convinced after several hours to return to its cage.

A few years later, Ms. Bouglione’s circus was traveling to Latin America when a storm nearly sank their ship, leading the captain to insist that they throw their 12 elephants overboard. The elephants were spared when the sea suddenly grew calm.

Ms. Bouglione insisted she was as comfortable with animals as she was with people, and boasted that she once trained a parrot in the art of profanity, used a hatbox to smuggle a baby gorilla inside her hotel, and developed a close connection with a leopard named Mickey. After he died, “of old age,” she memorialized him by turning him into a rug.

“I’ve always, always been with lions, with panthers, with wolves, with hyenas,” Ms. Bouglione told the Associated Press in 2014. “I was never scared.”

She was born Rosalie Van Been on Dec. 21, 1910, in a horse-drawn caravan traveling near Brussels. At the head of the train was her father, animal trainer Jules Van Been, who oversaw an operation that eventually grew to 100 carts.

Rosa, as she became known, joined him inside the lion cage as a teenager, performing “la danse serpentine” — a flowing, long-skirted dance that was performed without the aid of snakes (though she later handled anacondas). “The most dangerous thing was to enter the cage with the lions,” she told the Chinese television network CCTV. “But Daddy was there, and he paid attention, so I was not scared.”

She was 17 when she married Joseph Bouglione inside a cage filled with lions, in a ceremony that was illustrated and featured on French postcards and newspaper covers, and used for the title of her 2011 memoir, “A Wedding in the Lions’ Cage.” The priest was instructed to perform the ceremony while standing safely outside the cage.

The Bougliones worked with Buffalo Bill Cody’s Wild West shows, according to BBC News, before purchasing the Cirque d’Hiver. The ornate, 20-sided venue opened in 1852 just outside the Marais district in Paris, where it served as the city’s primary circus theater before being joined by the Cirque Medrano in the Montmartre neighborhood.

By the 1960s, Ms. Bouglione and her husband had become so successful that a nationally broadcast circus program was produced at the theater. International broadcasts soon followed, delivering Olympics-style circus events to viewers in the United States.

Yet the rise of television, the Bougliones said, led to a gradual decline in their audiences. By the mid-1980s, they had stopped touring altogether and had begun to pass control of the circus on to their children.

Joseph Bouglione died in 1987. According to her family, Ms. Bouglione is survived by 55 children and grandchildren. And while the venue she helped popularize remains in her family’s control, its schedule is now filled with concerts, wrestling matches and other live events free of snakes and somersaults.

A somewhat staged version of its circus heyday remains preserved on celluloid, captured in the 1956 film “Trapeze.” Shot at the Cirque d’Hiver and directed by Oscar-winning filmmaker Carol Reed, the movie features Burt Lancaster, Tony Curtis and Gina Lollobrigida as circus performers caught in a love triangle.

Behind the scenes, Cirque d’Hiver’s proprietors were credited with procuring a stunt animal for a shot in which Lancaster — a former circus acrobat — appeared alongside a lion.

Yes, Joseph Bouglione told the actor, he could practically guarantee his safety during the scene. “If by ‘practically’ you mean no more than the loss of an arm,” Lancaster replied, according to the New York Times, “then it’s a deal.”
