Background: Florence Nightingale was born on 12 May 1820 into a rich, upper-class, well-connected British family at the Villa Colombaia, in Florence, Tuscany, Italy, and was named after the city of her birth. Florence's older sister Frances Parthenope had similarly been named after her place of birth, Parthenope, a Greek settlement now part of the city of Naples. The family moved back to England in 1821, with Nightingale being brought up in the family's homes at Embley, Hampshire and Lea Hurst, Derbyshire. Florence inherited a liberal-humanitarian outlook from both sides of her family.
Context: Florence Nightingale exhibited a gift for mathematics from an early age and excelled in the subject under the tutelage of her father. Later, Nightingale became a pioneer in the visual presentation of information and statistical graphics. She used methods such as the pie chart, which had first been developed by William Playfair in 1801. While taken for granted now, it was at the time a relatively novel method of presenting data.  Indeed, Nightingale is described as "a true pioneer in the graphical representation of statistics", and is credited with developing a form of the pie chart now known as the polar area diagram, or occasionally the Nightingale rose diagram, equivalent to a modern circular histogram, to illustrate seasonal sources of patient mortality in the military field hospital she managed. Nightingale called a compilation of such diagrams a "coxcomb", but later that term would frequently be used for the individual diagrams. She made extensive use of coxcombs to present reports on the nature and magnitude of the conditions of medical care in the Crimean War to Members of Parliament and civil servants who would have been unlikely to read or understand traditional statistical reports. In 1859, Nightingale was elected the first female member of the Royal Statistical Society. In 1874 she became an honorary member of the American Statistical Association.  Her attention turned to the health of the British army in India and she demonstrated that bad drainage, contaminated water, overcrowding and poor ventilation were causing the high death rate. She concluded that the health of the army and the people of India had to go hand in hand and so campaigned to improve the sanitary conditions of the country as a whole.  Nightingale made a comprehensive statistical study of sanitation in Indian rural life and was the leading figure in the introduction of improved medical care and public health service in India. In 1858 and 1859, she successfully lobbied for the establishment of a Royal Commission into the Indian situation. Two years later, she provided a report to the commission, which completed its own study in 1863. "After 10 years of sanitary reform, in 1873, Nightingale reported that mortality among the soldiers in India had declined from 69 to 18 per 1,000".  The Royal Sanitary Commission of 1868-9 presented Nightingale with an opportunity to press for compulsory sanitation in private houses. She lobbied the minister responsible, James Stansfeld, to strengthen the proposed Public Health Bill to require owners of existing properties to pay for connection to mains drainage. The strengthened legislation was enacted in the Public Health Acts of 1874 and 1875. At the same time she combined with the retired sanitary reformer Edwin Chadwick to persuade Stansfeld to devolve powers to enforce the law to Local Authorities, eliminating central control by medical technocrats. Her Crimean War statistics had convinced her that non-medical approaches were more effective given the state of knowledge at the time. Historians now believe that both drainage and devolved enforcement played a crucial role in increasing average national life expectancy by 20 years between 1871 and the mid-1930s during which time medical science made no impact on the most fatal epidemic diseases.

Problem: Background: O'Neill was born in a hotel, the Barrett House, at Broadway and 43rd Street, on what was then Longacre Square (now Times Square). A commemorative plaque was first dedicated there in 1957. The site is now occupied by 1500 Broadway, which houses offices, retail, and ABC Studios. He was the son of Irish immigrant actor James O'Neill and Mary Ellen Quinlan, who was also of Irish descent.
Context: O'Neill was married to Kathleen Jenkins from October 2, 1909 to 1912, during which time they had one son, Eugene O'Neill, Jr. (1910-1950). In 1917, O'Neill met Agnes Boulton, a successful writer of commercial fiction, and they married on April 12, 1918. They lived in a home owned by her parents in Point Pleasant, New Jersey, after their marriage. The years of their marriage--during which the couple lived in Connecticut and Bermuda and had two children, Shane and Oona--are described vividly in her 1958 memoir Part of a Long Story. They divorced in 1929, after O'Neill abandoned Boulton and the children for the actress Carlotta Monterey (born San Francisco, California, December 28, 1888; died Westwood, New Jersey, November 18, 1970). O'Neill and Carlotta married less than a month after he officially divorced his previous wife.  In 1929, O'Neill and Monterey moved to the Loire Valley in central France, where they lived in the Chateau du Plessis in Saint-Antoine-du-Rocher, Indre-et-Loire. During the early 1930s they returned to the United States and lived in Sea Island, Georgia, at a house called Casa Genotta. He moved to Danville, California in 1937 and lived there until 1944. His house there, Tao House, is today the Eugene O'Neill National Historic Site.  In their first years together, Monterey organized O'Neill's life, enabling him to devote himself to writing. She later became addicted to potassium bromide, and the marriage deteriorated, resulting in a number of separations, although they never divorced.  In 1943, O'Neill disowned his daughter Oona for marrying the English actor, director, and producer Charlie Chaplin when she was 18 and Chaplin was 54. He never saw Oona again.  He also had distant relationships with his sons. Eugene O'Neill, Jr., a Yale classicist, suffered from alcoholism and committed suicide in 1950 at the age of 40. Shane O'Neill became a heroin addict and moved into the family home in Bermuda, Spithead, with his new wife, where he supported himself by selling off the furnishings. He was disowned by his father before also committing suicide (by jumping out of a window) a number of years later. Oona ultimately inherited Spithead and the connected estate (subsequently known as the Chaplin Estate). In 1950 O'Neill joined The Lambs, the famed theater club.
