Some context: 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.

Some context: James Whale (22 July 1889 - 29 May 1957) was an English film director, theater director and actor. He is best remembered for his four classic horror films: Frankenstein (1931), The Old Dark House (1932), The Invisible Man (1933) and Bride of Frankenstein (1935). Whale also directed films in other genres, including what is considered the definitive film version of the musical Show Boat (1936). He became increasingly disenchanted with his association with horror, but many of his non-horror films have fallen into obscurity.
After the armistice he returned to Birmingham and tried to find work as a cartoonist. He sold two cartoons to the Bystander in 1919 but was unable to secure a permanent position. Later that year he embarked on a professional stage career. Under the tutelage of actor-manager Nigel Playfair, he worked as an actor, set designer and builder, "stage director" (akin to a stage manager) and director. In 1922, while with Playfair, he met Doris Zinkeisen. They were considered a couple for some two years, despite Whale's living as an openly gay man. They were reportedly engaged in 1924, but by 1925 the engagement was off. In 1928 Whale was offered the opportunity to direct two private performances of R.C. Sherriff's then-unknown play Journey's End for the Incorporated Stage Society, a theatre society that mounted private Sunday performances of plays. Set over a four-day period in March 1918 in the trenches at Saint-Quentin, France, Journey's End gives a glimpse into the experiences of the officers of a British infantry company in World War I. The key conflict is between Capt. Stanhope, the company commander, and Lt. Raleigh, the brother of Stanhope's fiancee. Whale offered the part of Stanhope to the then barely known Laurence Olivier. Olivier initially declined the role, but after meeting the playwright agreed to take it on. Maurice Evans was cast as Raleigh. The play was well received and transferred to the Savoy Theatre in London's West End, opening on 21 January 1929. A young Colin Clive was now in the lead role, Olivier having accepted an offer to take the lead in a production of Beau Geste. The play was a tremendous success, with critics uniform and effusive in their praise and with audiences sometimes sitting in stunned silence following its conclusion only to burst into thunderous ovations. As Whale biographer James Curtis wrote, the play "managed to coalesce, at the right time and in the right manner, the impressions of a whole generation of men who were in the war and who had found it impossible, through words or deeds, to adequately express to their friends and families what the trenches had been like". After three weeks at the Savoy, Journey's End transferred to the Prince of Wales Theatre, where it ran for the next two years. With the success of Journey's End at home, Broadway producer Gilbert Miller acquired the rights to mount a New York production with an all-British cast headed by Colin Keith-Johnston as Stanhope and Derek Williams as Raleigh. Whale also directed this version, which premiered at Henry Miller's Theatre on 22 March 1929. The play ran for over a year and cemented its reputation as the greatest play about World War I.
