Background: Erik Weisz was born in Budapest to a Jewish family. His parents were Rabbi Mayer Samuel Weisz (1829-1892) and Cecilia Steiner (1841-1913). Houdini was one of seven children: Herman M. (1863-1885) who was Houdini's half-brother, by Rabbi Weisz's first marriage; Nathan J. (1870-1927); Gottfried William (1872-1925); Theodore (1876-1945); Leopold D. (1879-1962); and Carrie Gladys (1882-1959), who was left almost blind after a childhood accident. Weisz arrived in the United States on July 3, 1878, on the SS Fresia with his mother (who was pregnant) and his four brothers.
Context: Houdini performed at least three variations on a buried alive stunt during his career. The first was near Santa Ana, California in 1915, and it almost cost Houdini his life. Houdini was buried, without a casket, in a pit of earth six feet deep. He became exhausted and panicked while trying to dig his way to the surface and called for help. When his hand finally broke the surface, he fell unconscious and had to be pulled from the grave by his assistants. Houdini wrote in his diary that the escape was "very dangerous" and that "the weight of the earth is killing."  Houdini's second variation on buried alive was an endurance test designed to expose mystical Egyptian performer Rahman Bey, who had claimed to use supernatural powers to remain in a sealed casket for an hour. Houdini bettered Bey on August 5, 1926, by remaining in a sealed casket, or coffin, submerged in the swimming pool of New York's Hotel Shelton for one and a half hours. Houdini claimed he did not use any trickery or supernatural powers to accomplish this feat, just controlled breathing. He repeated the feat at the YMCA in Worcester, Massachusetts on September 28, 1926, this time remaining sealed for one hour and eleven minutes.  Houdini's final buried alive was an elaborate stage escape that featured in his full evening show. Houdini would escape after being strapped in a straitjacket, sealed in a casket, and then buried in a large tank filled with sand. While posters advertising the escape exist (playing off the Bey challenge by boasting "Egyptian Fakirs Outdone!"), it is unclear whether Houdini ever performed buried alive on stage. The stunt was to be the feature escape of his 1927 season, but Houdini died on October 31, 1926. The bronze casket Houdini created for buried alive was used to transport Houdini's body from Detroit to New York following his death on Halloween.
Question: Where else did he perform this stunt?
Answer: submerged in the swimming pool of New York's Hotel Shelton

Background: Abbot Howard Hoffman (November 30, 1936 - April 12, 1989) was an American political and social activist, anarchist, and revolutionary who co-founded the Youth International Party ("Yippies"). Hoffman was arrested and tried for conspiracy and inciting to riot as a result of his role in protests that led to violent confrontations with police during the 1968 Democratic National Convention, along with Jerry Rubin, David Dellinger, Tom Hayden, Rennie Davis, John Froines, Lee Weiner, and Bobby Seale. The group was known collectively as the "Chicago Eight"; when Seale's prosecution was separated from the others, they became known as the Chicago Seven. While the defendants were initially convicted of intent to incite a riot, the verdicts were overturned on appeal.
Context: At Woodstock in 1969, Hoffman reportedly interrupted The Who's performance to attempt to speak against the jailing of John Sinclair of the White Panther Party. He grabbed a microphone and yelled, "I think this is a pile of shit while John Sinclair rots in prison ..." Pete Townshend was adjusting his amplifier between songs and turned to look at Hoffman over his left shoulder. Townshend shouted "Fuck off! Fuck off my fucking stage!" and reportedly ran at Hoffman with his guitar and hit Hoffman in the back, although Townshend later denied attacking Hoffman. Townshend later said that while he actually agreed with Hoffman on Sinclair's imprisonment, he would have knocked him offstage regardless of the content of his message, given that Hoffman had violated the "sanctity of the stage," i.e., the right of the band to perform uninterrupted by distractions not relevant to the show. The incident took place during a camera change, and was not captured on film. The audio of this incident, however, can be heard on The Who's box set, Thirty Years of Maximum R&B (Disc 2, Track 20, "Abbie Hoffman Incident").  In 1971's Steal This Book in the section "Free Communication," Hoffman encourages his readership to take to the stage at rock concerts to use the pre-assembled audience and PA system to get their message out. However he mentions that "interrupting the concert is frowned upon since it is only spitting in the faces of people you are trying to reach."  In Woodstock Nation, Hoffman mentions the incident, and says he was on a bad LSD trip at the time. Joe Shea, then a reporter for the Times Herald-Record, newspaper that covered the event on-site, said he saw the incident. He recalled that Hoffman was actually hit in the back of the head by Townshend's guitar and toppled directly into the pit in front of the stage. He does not recall any "shove" from Townshend, and discounts both men's accounts.
