Thomas Chatterton (20 November 1752 - 24 August 1770) was an English poet whose precocious talents ended in suicide at age 17. He became a heroic tragic figure in Romantic art. Although fatherless and raised in poverty, he was an exceptionally studious child, publishing mature work by the age of 11. He was able to pass off his work as that of an imaginary 15th-century poet called Thomas Rowley, chiefly because few people at the time were familiar with medieval poetry, though he was denounced by Horace Walpole.
Chatterton was born in Bristol where the office of sexton of St Mary Redcliffe had long been held by the Chatterton family. The poet's father, also named Thomas Chatterton, was a musician, a poet, a numismatist, and a dabbler in the occult. He had been a sub-chanter at Bristol Cathedral and master of the Pyle Street free school, near Redcliffe church. After Chatterton's birth (15 weeks after his father's death on 7 August 1752), his mother established a girls' school and took in sewing and ornamental needlework. Chatterton was admitted to Edward Colston's Charity, a Bristol charity school, in which the curriculum was limited to reading, writing, arithmetic and the catechism. Chatterton, however, was always fascinated with his uncle the sexton and the church of St Mary Redcliffe. The knights, ecclesiastics and civic dignitaries on its altar tombs became familiar to him. Then he found a fresh interest in oaken chests in the muniment room over the porch on the north side of the nave, where parchment deeds, old as the Wars of the Roses, lay forgotten. Chatterton learned his first letters from the illuminated capitals of an old musical folio, and he learned to read out of a black-letter Bible. He did not like, his sister said, reading out of small books. Wayward from his earliest years, and uninterested in the games of other children, he was thought to be educationally backward. His sister related that on being asked what device he would like painted on a bowl that was to be his, he replied, "Paint me an angel, with wings, and a trumpet, to trumpet my name over the world." From his earliest years, he was liable to fits of abstraction, sitting for hours in what seemed like a trance, or crying for no reason. His lonely circumstances helped foster his natural reserve, and to create the love of mystery which exercised such an influence on the development of his poetry. When Chatterton was age 6, his mother began to recognise his capacity; at age 8, he was so eager for books that he would read and write all day long if undisturbed; by the age of 11, he had become a contributor to Felix Farley's Bristol Journal. His confirmation inspired him to write some religious poems published in that paper. In 1763, a cross which had adorned the churchyard of St Mary Redcliffe for upwards of three centuries was destroyed by a churchwarden. The spirit of veneration was strong in Chatterton, and he sent to the local journal on 7 January 1764 a satire on the parish vandal. He also liked to lock himself in a little attic which he had appropriated as his study; and there, with books, cherished parchments, loot purloined from the muniment room of St Mary Redcliffe, and drawing materials, the child lived in thought with his 15th-century heroes and heroines.

Was he a regular contributor?

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."
