Some context: Alice Hamilton (February 27, 1869 - September 22, 1970) was an American physician, research scientist, and author who is best known as a leading expert in the field of occupational health and a pioneer in the field of industrial toxicology. She was also the first woman appointed to the faculty of Harvard University. Her scientific research focused on the study of occupational illnesses and the dangerous effects of industrial metals and chemical compounds. In addition to her scientific work, Hamilton was a social-welfare reformer, humanitarian, peace activist, and a resident-volunteer at Hull House in Chicago.
Hamilton began her long career in public health and workplace safety in 1910, when Illinois governor Charles S. Deneen appointed her as a medical investor to the newly-formed Illinois Commission on Occupational Diseases. Hamilton lead the commission's investigations, which focused on industrial poisons such as lead and other toxins. She also authored the "Illinois Survey," the commission's report that documented its findings of industrial processes that exposed workers to lead poisoning and other illnesses. The commission's efforts resulted in the passage of the first workers' compensation laws in Illinois in 1911, in Indiana in 1915, and occupational disease laws in other states. The new laws required employers to take safety precautions to protect workers. By 1916 Hamilton had become America's leading authority on lead poisoning. For the next decade she investigated a range of issues for a variety of state and federal health committees. Hamilton focused her explorations on occupational toxic disorders, examining the effects of substances such as aniline dyes, carbon monoxide, mercury, tetraethyl lead, radium, benzene, carbon disulfide and hydrogen sulfide gases. In 1925, at a Public Health Service conference on the use of lead in gasoline, she testified against the use of lead and warned of the danger it posed to people and the environment. Nevertheless, leaded gasoline was allowed. The EPA in 1988 estimated that over the previous 60 years that 68 million children suffered high toxic exposure to lead from leaded fuels. Her work on the manufacture of white lead and lead oxide, as a special investigator for the U.S. Bureau of Labor Statistics, is considered a "landmark study". Relying primarily on "shoe leather epidemiology" (her process of making personal visits to factories, conducting interviews with workers, and compiling details of diagnosed poisoning cases) and the emerging laboratory science of toxicology, Hamilton pioneered occupational epidemiology and industrial hygiene. She also created the specialized field of industrial medicine in the United States. Her findings were scientifically persuasive and influenced sweeping health reforms that changed laws and general practice to improve the health of workers. During World War I, the US Army tasked her with solving a mysterious ailment striking workers at a munitions plant in New Jersey. She led a team that included George Minot, a Professor at Harvard Medical School. She deduced that the workers were being sickened through contact with the explosive trinitrotoluene (TNT). Her recommendations that workers wear protective clothing that should be removed and washed at the end of each shift solved the problem. Hamilton's best-known research included her studies on carbon monoxide poisoning among American steelworkers, mercury poisoning of hatters, and "a debilitating hand condition developed by workers using jackhammers." At the request of the U.S. Department of Labor, she also investigated industries involved in developing high explosives, "spastic anemia known as 'dead fingers'" among Bedford, Indiana, limestone cutters, and the "unusually high incidence of pulmonary tuberculosis" among tombstone carvers working in the granite mills of Quincy, Massachusetts, and Barre, Vermont. Hamilton was also a member of the Committee for the Scientific Investigation of the Mortality from Tuberculosis in Dusty Trades, whose efforts "laid the groundwork for further studies and eventual widespread reform in the industry."

Some context: Sir Richard Starkey (born 7 July 1940), known professionally as Ringo Starr, is an English musician, songwriter, singer, and actor who gained worldwide fame as the drummer for the Beatles. He occasionally sang lead vocals, usually for one song on an album, including "With a Little Help from My Friends", "Yellow Submarine", "Good Night", and their cover of "Act Naturally". He also wrote the Beatles' songs "Don't Pass Me By" and "Octopus's Garden", and is credited as a co-writer of others, including "What Goes On" and "Flying". Starr was twice afflicted by life-threatening illnesses during childhood, and he fell behind in school as a result of prolonged hospitalisations.
Starr and the other members of the Beatles were appointed Members of the Order of the British Empire (MBE) in the 1965 Birthday Honours; they received their insignia from Queen Elizabeth II at an investiture at Buckingham Palace on 26 October. He and the other Beatles were cumulatively nominated for a BAFTA Award for Best Newcomer for their performances in the 1964 film A Hard Day's Night. In 1971, the Beatles received an Academy Award for Best Original Song Score for the film Let It Be. The minor planet 4150 Starr, discovered on 31 August 1984 by Brian A. Skiff at the Anderson Mesa Station of the Lowell Observatory, was named in Starr's honour. Starr was nominated for a 1989 Daytime Emmy Award for Outstanding Performer in a Children's Series for his role as Mr. Conductor in the television series Shining Time Station. In 2015, twenty-three years after he was inducted into the Rock and Roll Hall of Fame as one of the Beatles, Starr became the last Beatle to be inducted for a solo career. During the 50th Grammy Awards, Starr, George Martin and his son Giles accepted the Best Compilation Soundtrack award for Love. On 9 November 2008, Starr accepted a Diamond Award on behalf of the Beatles during the 2008 World Music Awards ceremony in Monaco. On 8 February 2010, he was honoured with the 2,401st star on the Hollywood Walk of Fame by the Hollywood Chamber of Commerce. It is located at 1750 North Vine Street, in front of the Capitol Records building, as are the stars for Lennon, McCartney and Harrison. Starr was appointed a Knight Bachelor in the 2018 New Year Honours for services to music. He was knighted in an investiture ceremony at Buckingham Palace by Prince William, Duke of Cambridge on 20 March 2018.
