Question: 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."

Problem: The Shadow is the name of a collection of serialized dramas, originally in 1930s pulp novels, and then in a wide variety of media, and it is also used to refer to the character featured in The Shadow media. One of the most famous adventure heroes of the 20th century United States, the Shadow has been featured on the radio, in a long-running pulp magazine series, in American comic books, comic strips, television, serials, video games, and at least five films. The radio drama included episodes voiced by Orson Welles. Originally simply a mysterious radio narrator who hosted a program designed to promote magazine sales for Street and Smith Publications, The Shadow was developed into a distinctive literary character, later to become a pop culture icon, by writer Walter B. Gibson in 1931.

In print, The Shadow's real name is Kent Allard, and he was a famed aviator who fought for the French during World War I. He became known by the alias the Black Eagle, according to The Shadow's Shadow (1933), although later stories revised this alias as the Dark Eagle, beginning with The Shadow Unmasks (1937). After the war, Allard finds a new challenge in waging war on criminals. Allard falsifies his death in the South American jungles, then returns to the United States. Arriving in New York City, he adopts numerous identities to conceal his existence. One of the identities Allard assumes--indeed, the best known--is that of Lamont Cranston, a "wealthy young man-about-town." In the pulps, Cranston is a separate character; Allard frequently disguises himself as Cranston and adopts his identity (The Shadow Laughs, 1931). While Cranston travels the world, Allard assumes his identity in New York. In their first meeting, Allard, as The Shadow, threatens Cranston, saying he has arranged to switch signatures on various documents and other means that will allow him to take over the Lamont Cranston identity entirely unless Cranston agrees to allow Allard to impersonate him when he is abroad. Although alarmed at first, Cranston is amused by the irony of the situation and agrees. The two men sometimes meet in order to impersonate each other (Crime over Miami, 1940). The disguise works well because Allard and Cranston resemble each other (Dictator of Crime, 1941). His other disguises include businessman Henry Arnaud, who first appeared in The Black Master (March 1, 1932), which revealed that like Cranston, there is a real Henry Arnaud; elderly Isaac Twambley, who first appeared in No Time For Murder; and Fritz, who first appeared in The Living Shadow (April 1931); in this last disguise, he sometimes takes the place of the doddering old slow-witted, uncommunicative janitor who works at Police Headquarters in order to listen in on conversations and to look at evidence. For the first half of The Shadow's tenure in the pulps, his past and identity are ambiguous. In The Living Shadow, a thug claims to have seen the Shadow's face, and thought he saw "a piece of white that looked like a bandage." In The Black Master and The Shadow's Shadow, the villains both see The Shadow's true face and remark that The Shadow is a man of many faces with no face of his own. It was not until the August 1937 issue, The Shadow Unmasks, that The Shadow's real name is revealed. In the radio drama, the Allard secret identity was dropped for simplicity's sake. On the radio, The Shadow was only Lamont Cranston; he had no other aliases or disguises.
