IN: Irving Grant Thalberg (May 30, 1899 - September 14, 1936) was an American film producer during the early years of motion pictures. He was called "The Boy Wonder" for his youth and ability to select scripts, choose actors, gather production staff, and make profitable films, including Grand Hotel, China Seas, Camille, Mutiny on the Bounty, and The Good Earth. His films carved out an international market, "projecting a seductive image of American life brimming with vitality and rooted in democracy and personal freedom," states biographer Roland Flamini.

Thalberg was born in Brooklyn, to German Jewish immigrant parents, William and Henrietta (Haymann). Shortly after birth, he was diagnosed with "blue baby syndrome," caused by a congenital disease that limited the oxygen supply to his heart. The prognosis from the family's doctor and specialists was that he might live to age twenty, or at most, age thirty.  During his high school years in Brooklyn, he began having attacks of chest pains, dizziness and fatigue. This affected his ability to study, though until that time he was a good student. When he was 17, he contracted rheumatic fever, and was confined to bed for a year. His mother, Henrietta, to prevent him falling too far behind other students, brought him homework from school, books, and tutors to teach him at home. She also hoped that the schoolwork and reading would distract him from the "tantalizing sounds" of children playing outside his window.  With little to entertain him, he read books as a main activity. He devoured popular novels, classics, plays, and biographies. His books, of necessity, replaced the streets of New York, and led to his interest in classical philosophy and philosophers, such as William James.  When Thalberg returned to school, he finished high school but lacked the stamina for college, which he felt would have required constant late-night studying and cramming for exams. Instead, he took part-time jobs as a store clerk, and in the evenings, to gain some job skills, taught himself typing, shorthand and Spanish at a night vocational school. When he turned 18, he placed an ad with the local newspaper hoping to find better work:  "Situation Wanted: Secretary, stenographer, Spanish, English, high school education, no experience; $15."

IN: 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.

In 1904, the London Daily Mirror newspaper challenged Houdini to escape from special handcuffs that it claimed had taken Nathaniel Hart, a locksmith from Birmingham, five years to make. Houdini accepted the challenge for March 17 during a matinee performance at London's Hippodrome theater. It was reported that 4000 people and more than 100 journalists turned out for the much-hyped event. The escape attempt dragged on for over an hour, during which Houdini emerged from his "ghost house" (a small screen used to conceal the method of his escape) several times. On one occasion he asked if the cuffs could be removed so he could take off his coat. The Mirror representative, Frank Parker, refused, saying Houdini could gain an advantage if he saw how the cuffs were unlocked. Houdini promptly took out a pen-knife and, holding the knife in his teeth, used it to cut his coat from his body. Some 56 minutes later, Houdini's wife appeared on stage and gave him a kiss. Many thought that in her mouth was the key to unlock the special handcuffs. However, it has since been suggested that Bess did not in fact enter the stage at all, and that this theory is unlikely due to the size of the 6-inch key Houdini then went back behind the curtain. After an hour and ten minutes, Houdini emerged free. As he was paraded on the shoulders of the cheering crowd, he broke down and wept. Houdini later said it was the most difficult escape of his career.  After Houdini's death, his friend Martin Beck was quoted in Will Goldston's book, Sensational Tales of Mystery Men, as admitting that Houdini was bested that day and had appealed to his wife, Bess, for help. Goldston goes on to claim that Bess begged the key from the Mirror representative, then slipped it to Houdini in a glass of water. It was stated in the book The Secret Life of Houdini that the key required to open the specially designed Mirror handcuffs was 6 inches long, and could not have been smuggled to Houdini in a glass of water. Goldston offered no proof of his account, and many modern biographers have found evidence (notably in the custom design of the handcuffs) that the Mirror challenge may have been arranged by Houdini and that his long struggle to escape was pure showmanship.  This escape was discussed in depth on the Travel Channel's Mysteries at the Museum in an interview with Houdini expert, magician and escape artist Dorothy Dietrich of Scranton's Houdini Museum.  A full-sized design of the same Mirror Handcuffs, as well as a replica of the Bramah style key for it, is on display to the public at The Houdini Museum in Scranton, Pennsylvania. This set of cuffs is believed to be one of only six in the world, some of which are not on display.
QUESTION:
Did he perform this challenge more than once?
