IN: William Randolph Hearst Sr. (; April 29, 1863 - August 14, 1951) was an American businessman, politician, and newspaper publisher who built the nation's largest newspaper chain and media company Hearst Communications and whose flamboyant methods of yellow journalism influenced the nation's popular media by emphasizing sensationalism and human interest stories. Hearst entered the publishing business in 1887 after being given control of The San Francisco Examiner by his wealthy father.

William R. Hearst was born in San Francisco, to millionaire mining engineer, goldmine owner and U.S. senator (1886-91) George Hearst and his wife Phoebe Apperson Hearst.  His paternal great-grandfather was John Hearst, of Ulster Protestant origin. John Hearst migrated to America from Ballybay, County Monaghan as part of the Cahans Exodus with his wife and six children in 1766 and settled in South Carolina. Their immigration to South Carolina was spurred in part by the colonial government's policy that encouraged the immigration of Irish Protestants. The names "John Hearse" and "John Hearse Jr." appear on the council records of October 26, 1766, being credited with meriting 400 and 100 acres (1.62 and 0.40 km2) of land on the Long Canes (in what became Abbeville District), based upon 100 acres (0.40 km2) to heads of household and 50 acres (20 ha) for each dependent of a Protestant immigrant. The "Hearse" spelling of the family name never was used afterward by the family members themselves, or any family of any size. A separate theory purports that one branch of a "Hurst" family of Virginia (originally from Plymouth Colony) moved to South Carolina at about the same time and changed the spelling of its surname of over a century to that of the immigrant Hearsts. Hearst's mother, nee Phoebe Elizabeth Apperson, was also of Irish ancestry; her family came from Galway. She was the first woman regent of University of California, Berkeley, funded many anthropological expeditions and founded the Phoebe A. Hearst Museum of Anthropology.  Following preparation at St. Paul's School in Concord, New Hampshire, Hearst enrolled in the Harvard College class of 1885. While there he was a member of Delta Kappa Epsilon, the A.D. Club (a Harvard Final club), the Hasty Pudding Theatricals, and of the Lampoon before being expelled for antics ranging from sponsoring massive beer parties in Harvard Square to sending pudding pots used as chamber pots to his professors (their images were depicted within the bowls).

input: 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."
