Problem: Eileen Jeanette Vancho Lyttle Garrett (17 March 1893 - 15 September 1970) was an Irish medium and parapsychologist. Garrett's alleged psychic abilities were tested in the 1930s by Joseph Rhine and others. Rhine claimed that she had genuine psychic abilities, but subsequent studies were unable to replicate his results, and Garrett's abilities were later shown to be consistent with chance guessing. Garrett elicited controversy after the R101 crash, when she held a series of seances at the National Laboratory of Psychical Research claiming to be in contact with victims of the disaster.

On 7 October 1930 it was claimed by spiritualists that Garrett made contact with the spirit of Herbert Carmichael Irwin at a seance held with Harry Price at the National Laboratory of Psychical Research two days after the R101 disaster, while attempting to contact the then recently deceased Arthur Conan Doyle, and discussed possible causes of the accident. The event "attracted worldwide attention", thanks to the presence of a reporter. Major Oliver Villiers, a friend of Brancker, Scott, Irwin, Colmore and others aboard the airship, participated in further seances with Garrett, at which he claimed to have contacted both Irwin and other victims. Price did not come to any definite conclusion about Garrett and the seances:  It is not my intention to discuss if the medium were really controlled by the discarnate entity of Irwin, or whether the utterances emanated from her subconscious mind or those of the sitters. "Spirit" or "trance personality" would be equally interesting explanations - and equally remarkable. There is no real evidence for either hypothesis. But it is not my intention to discuss hypotheses, but rather to put on record the detailed account of a remarkably interesting and thought-provoking experiment.  In 1978, paranormal writer John G. Fuller wrote a book claiming that Irwin had spoken through Garrett. This claim has been questioned. Magician John Booth analyzed the mediumship of Garrett and the paranormal claims of R101 and considered her to be a fraud. According to Booth, Garrett's notes and writings show she followed the building of the R101 and she may have been given aircraft blueprints from a technician from the aerodrome.  However, Melvin Harris a researcher who studied the original scripts from the case, wrote that no secret accomplice was needed as the information described in Garrett's seances were "either commonplace, easily absorbed bits and pieces, or plain gobbledegook. The so-called secret information just doesn't exist." Harris discovered that the original scripts of the seances did not contain any secret information and spiritualist writers such as Fuller had fabricated and misinterpreted content from these scripts. When experts and veteran pilots were shown the scripts they declared the information to be incorrect and technically empty.  Archie Jarman who had interviewed witnesses wrote an 80,000-word report on the case concluded the seance information was valueless and that we should "best forget the psychic side of R-101; it's a dead duck-- absolutely!"

Question:
Jonas Edward Salk (; October 28, 1914 - June 23, 1995) was an American medical researcher and virologist. He discovered and developed one of the first successful polio vaccines. Born in New York City, he attended New York University School of Medicine, later choosing to do medical research instead of becoming a practicing physician. In 1939, after earning his medical degree, Salk began an internship as a physician scientist at Mount Sinai Hospital.
In 1947, Salk became ambitious for his own lab and was granted one at the University of Pittsburgh, but the lab was smaller than he had hoped and he found the rules imposed by the university restrictive. In 1948, Harry Weaver, the director of research at the National Foundation for Infantile Paralysis, contacted Salk. He asked Salk to find out if there were more types of polio than the three then known, offering additional space, equipment and researchers. For the first year he gathered supplies and researchers including Julius Youngner, Byron Bennett, L. James Lewis, and secretary Lorraine Friedman joined Salk's team, as well. As time went on, Salk began securing grants from the Mellon family and was able to build a working virology laboratory. He later joined the National Foundation for Infantile Paralysis's polio project established by President Franklin D. Roosevelt.  Extensive publicity and fear of polio led to much increased funding, $67 million by 1955, but research continued on dangerous live vaccines. Salk decided to use the safer 'killed' virus, instead of weakened forms of strains of polio viruses like the ones used contemporarily by Albert Sabin, who was developing an oral vaccine. After successful tests on laboratory animals, on July 2, 1952, assisted by the staff at the D.T. Watson Home for Crippled Children, Salk injected 43 children with his killed-virus vaccine. A few weeks later, Salk injected children at the Polk State School for the retarded and feeble-minded. In 1954 he tested the vaccine on about one million children, known as the polio pioneers. The vaccine was announced as safe on April 12, 1955.  The project became large, involving 100 million contributors to the March of Dimes, and 7 million volunteers. The foundation allowed itself to go into debt to finance the final research required to develop the Salk vaccine. Salk worked incessantly for two and a half years.  Salk's inactivated polio vaccine was the first vaccine for the disease; it came into use in 1955. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system.
