IN: Slotin was the first of three children born to Israel and Sonia Slotin, Yiddish-speaking refugees who had fled the pogroms of Russia to Winnipeg, Manitoba. He grew up in the North End neighborhood of Winnipeg, an area with a large concentration of Eastern European immigrants. From his early days at Machray Elementary School through his teenage years at St. John's High School, Slotin was academically exceptional. His younger brother, Sam, later remarked that his brother "had an extreme intensity that enabled him to study long hours."

On 21 May 1946, with seven colleagues watching, Slotin performed an experiment that involved the creation of one of the first steps of a fission reaction by placing two half-spheres of beryllium (a neutron reflector) around a 3.5-inch-diameter (89 mm) plutonium core. The experiment used the same 6.2-kilogram (13.7 lb) plutonium core that had irradiated Harry Daghlian, later called the "demon core" for its role in the two accidents. Slotin grasped the upper 228.6 mm (9-inch) beryllium hemisphere with his left hand through a thumb hole at the top while he maintained the separation of the half-spheres using the blade of a screwdriver with his right hand, having removed the shims normally used. Using a screwdriver was not a normal part of the experimental protocol.  At 3:20 p.m., the screwdriver slipped and the upper beryllium hemisphere fell, causing a "prompt critical" reaction and a burst of hard radiation. At the time, the scientists in the room observed the blue glow of air ionization and felt a heat wave. Slotin experienced a sour taste in his mouth and an intense burning sensation in his left hand. He jerked his left hand upward, lifting the upper beryllium hemisphere and dropping it to the floor, ending the reaction. However, he had already been exposed to a lethal dose of neutron radiation. At the time of the accident, dosimetry badges were in a locked box about 100 feet (30 m) from the accident. Realizing that no one in the room had their film badges on, "immediately after the accident Dr. Slotin asked to have the badges taken from the lead box and placed on the critical assembly". This peculiar response was attributed to "vertigo" and was of no value for determining the actual doses received by the men in the room.  Others in the room at the time included Raemer E. Schreiber, Alvin Cushman Graves, Stanley Allan Kline, Marion Edward Cieslicki, Dwight Smith Young, Theodore P. Perlman, and Pvt. Patrick J. Cleary.  As soon as Slotin left the building, he vomited, a common reaction from exposure to extremely intense ionizing radiation. Slotin's colleagues rushed him to the hospital, but the radiation damage was irreversible.  By 25 May 1946, four of the eight men exposed during the incident had been discharged from hospital. The Army doctor responsible for the hospital, Captain Paul Hageman, said that Slotin's, Graves', Kline's and Young's "immediate condition is satisfactory."

IN: The Who are an English rock band that formed in 1964. Their classic line-up consisted of lead singer Roger Daltrey, guitarist and singer Pete Townshend, bass guitarist John Entwistle, and drummer Keith Moon. They are considered one of the most influential rock bands of the 20th century, selling over 100 million records worldwide and holding a reputation for their live shows and studio work. The Who developed from an earlier group, the Detours, and established themselves as part of the pop art and mod movements, featuring auto-destructive art by destroying guitars and drums on stage.

Tommy secured the Who's future, and made them millionaires. The group reacted in different ways--Daltrey and Entwistle lived comfortably, Townshend was embarrassed at his wealth, which he felt was at odds with Meher Baba's ideals, and Moon spent frivolously.  During the latter part of 1970, Townshend plotted a follow up Tommy: Lifehouse, which was to be a multi-media project symbolising the relationship between an artist and his audience. He developed ideas in his home studio, creating layers of synthesizers, and the Young Vic theatre in London was booked for a series of experimental concerts. Townshend approached the gigs with optimism; the rest of the band were just happy to be gigging again. Eventually, the others complained to Townshend that the project was too complicated and they should simply record another album. Things deteriorated until Townshend had a nervous breakdown and abandoned Lifehouse.  Entwistle was the first member of the group to release a solo album, Smash Your Head Against the Wall, in May 1971.  Recording at the Record Plant in New York City in March 1971 was abandoned when Lambert's addiction to hard drugs interfered with his ability to produce. The group restarted with Glyn Johns in April. The album was mostly Lifehouse material, with one unrelated song by Entwistle, "My Wife", and was released as Who's Next in August. The album reached No. 1 in the UK and No. 4 in the US. "Baba O'Riley" and "Won't Get Fooled Again" are early examples of synthesizer use in rock, featuring keyboard sounds generated in real time by a Lowrey organ; on "Won't Get Fooled Again", it was further processed through a VCS3 synthesizer. The synthesizer intro to "Baba O'Riley" was programmed based on Meher Baba's vital stats, and the track featured a violin solo by Dave Arbus. The album was a critical and commercial success, and has been certified 3x platinum by the RIAA. The Who continued to issue Lifehouse-related material over the next few years, including the singles "Let's See Action", "Join Together" and "Relay".  The band went back on tour, and "Baba O' Riley" and "Won't Get Fooled Again" became live favourites. In November they performed at the newly opened Rainbow Theatre in London for three nights, continuing in the US later that month, where Robert Hilburn of the Los Angeles Times described the Who as "the Greatest Show on Earth". The tour was slightly disrupted at the Civic Auditorium in San Francisco on 12 December when Moon passed out over his kit after overdosing on brandy and barbiturates. He recovered and completed the gig, playing to his usual strength.
