Problem: Duke was born in New York City, the only child of tobacco and hydroelectric power tycoon James Buchanan Duke and his second wife, Nanaline Holt Inman, widow of Dr. William Patterson Inman. At his death in 1925, the elder Duke's will bequeathed the majority of his estate to his wife and daughter, along with $17 million in two separate clauses of the will, to The Duke Endowment he had created in 1924. The total value of the estate was not disclosed, but was estimated variously at $60 million to $100 million (equivalent to $837 million to $1.395 billion in 2018), the majority culled from J.B. Duke's holds in Lucky Strike cigarettes. Duke spent her early childhood at Duke Farms, her father's 2,700-acre (11 km2) estate in Hillsborough Township, New Jersey.

Duke's first major philanthropic act was to establish Independent Aid, Inc., in 1934, when she was 21 years old, in order to manage the many requests for financial assistance addressed to her. In 1958, she established the Duke Gardens Foundation to endow the public display gardens she started to create at Duke Farms. Her Foundation intended that Duke Gardens "reveal the interests and philanthropic aspirations of the Duke family, as well as an appreciation for other cultures and a yearning for global understanding.". Duke Gardens were the center of a controversy over the decision by the trustees of the Doris Duke Charitable Foundation to close them on May 25, 2008. In 1968, Duke created the Newport Restoration Foundation with the goal of preserving more than eighty colonial buildings in the town. Historic properties include Rough Point, Samuel Whitehorne House, Prescott Farm, the Buloid-Perry House, the King's Arms Tavern, the Baptist Meetinghouse, and the Cotton House. Seventy-one buildings are rented to tenants. Only five function as museums. She also funded the construction of Maharishi Mahesh Yogi's ashram in India, visited by the Beatles in 1968. Duke's extensive travels led to an interest in a variety of cultures, and during her lifetime she amassed a considerable collection of Islamic and Southeast Asian art. After her death, numerous pieces were donated to The Asian Art Museum of San Francisco and the Walters Art Museum of Baltimore. Duke did much additional philanthropic work and was a major benefactor of medical research and child welfare programs. In the late 1980s, Duke donated $2 million to Duke University to be used for AIDS research. Her foundation, Independent Aid, became the Doris Duke Foundation, which still exists as a private grant-making entity. After her death, the Doris Duke Charitable Foundation was established in 1996, supporting four national grant making programs and Doris Duke's three estates, Shangri La, Rough Point, and Duke Farms.

Is there anything else interesting about her successes in Philanthropy?

Problem: Marie Charlotte Carmichael Stopes (15 October 1880 - 2 October 1958) was a British author, palaeobotanist and campaigner for eugenics and women's rights. She made significant contributions to plant palaeontology and coal classification, and was the first female academic on the faculty of the University of Manchester. With her second husband, Humphrey Verdon Roe, Stopes founded the first birth control clinic in Britain. Stopes edited the newsletter Birth Control News, which gave explicit practical advice.

During Stopes's time at Manchester, she studied coal and coal balls and researched the collection of Glossopteris (Permian seed ferns). This was an attempt to prove the theory of Eduard Suess concerning the existence of Gondwana or Pangaea. A chance meeting with Antarctic explorer Robert Falcon Scott during one of his fund-raising lectures in 1904 brought a possibility of proving Suess's theory. Stopes's passion to prove Suess's theory led her to discuss the possibility of joining Scott's next expedition to Antarctica. She did not join the expedition, but Scott promised to bring back samples of fossils to provide evidence for the theory. Scott died during the 1912 Terra Nova Expedition, but fossils of plants from the Queen Maud Mountains found near Scott's and his companions' bodies provided this evidence. In 1907, Stopes went to Japan on a scientific mission. She spent eighteen months at the Imperial University, Tokyo and explored coal mines on Hokkaido for fossilised plants. She published her Japanese experiences as a diary, called "Journal from Japan: a daily record of life as seen by a scientist", in 1910. In 1910, the Geological Survey of Canada commissioned Stopes to determine the age of the Fern Ledges, a geological structure at Saint John, New Brunswick. It is part of the Early Pennsylvanian epoch Lancaster Formation. Canadian scholars were divided between dating it to the Devonian period or to the Pennsylvanian/Upper Carboniferous period. Stopes arrived in North America before Christmas to start her research. On 29 December, she met the Canadian researcher Reginald Ruggles Gates in St. Louis, Missouri; they became engaged two days later. Starting her work on the Fern Ledges in earnest in February 1911, she did geological field work and researched at geological collections in museums, and shipped specimens to England for further investigation. The couple married in March and returned to England on 1 April that year. Stopes continued her research. In mid-1912 she delivered her results, finding for the Pennsylvanian period of the Carboniferous. The Government of Canada published her results in 1914. Later the same year, her marriage to Gates was annulled.[1] During the First World War, Stopes was engaged in studies of coal for the British government, which culminated in the writing of "Monograph on the constitution of coal" with R.V. Wheeler in 1918. The success of Stopes' work on marriage issues and birth control led her to reduce her scholarly work; her last scientific publications were in 1935. According to W. G. Chaloner (2005), "between 1903 and 1935 she published a series of palaeobotanical papers that placed her among the leading half-dozen British palaeobotanists of her time". Stopes made major contributions to knowledge of the earliest angiosperms, the formation of coal balls and the nature of coal macerals. The classification scheme and terminology she devised for coal are still being used. Stopes also wrote a popular book on palaeobotany, "Ancient Plants" (1910; Blackie, London), in what was called a successful pioneering effort to introduce the subject to non-scientists.
