Miguel Juan Sebastián Piñera Echenique (Spanish pronunciation: [miˈɣel ˈxwan sevasˈtjan piˈɲeɾa etʃeˈnice]; born December 1, 1949) is a Chilean businessman and politician. He was elected President of Chile in January 2010, taking office in March 2010.

One year after his birth, Piñera's family moved abroad to Belgium and later to New York City where his father was the Chilean ambassador to the United Nations. Piñera returned to Chile in 1955 and was enrolled in the Colegio del Verbo Divino ("Divine Word College"), from which he graduated in 1967.

Piñera then matriculated at the Pontifical Catholic University of Chile to undertake his undergraduate degree in Business and Administration, from which he graduated in 1971. Upon graduation, he was awarded the Raúl Iver Oxley Prize which is given to the best overall student of each class.

Piñera continued on to study at Harvard University on a partial Fulbright Program for his postgraduate studies in economics. During his time at Harvard, Piñera and a classmate co-authored an article titled, "The Old South's Stake in the Inter-Regional Movement of Slaves" for the Journal of Economic History. After three years at Harvard, Piñera graduated with both a M.A. and Ph.D. in Economics.

Juan Evo Morales Ayma (born October 26, 1959), popularly known as Evo (Spanish pronunciation: [ˈeβo]), is a Bolivian politician and activist, serving as the 80th President of Bolivia, a position that he has held since 2006. He is also the leader of both the Movement for Socialism party (MAS) and the cocalero trade union. Politically a socialist, his presidency has seen a focus on implementing leftist policies in the country, introducing a new constitution, land reforms, nationalising various key industries, opposing United States and corporate involvement in the country's politics, and poverty reduction measures.

Born into a working class Aymara family in Isallawi, Orinoca Canton, Evo grew up aiding his parents as a subsistence farmer. After studying for a degree, Morales undertook national service until 1978, when he returned to the family profession of farming, moving with them to Chapare Province. He eventually settled into growing coca, the plant from which cocaine is made. His activism led him into the political arena, and he eventually became the leader of the MAS, through which he got involved in social protests like the gas conflict and the Cochabamba protests of 2000. The MAS claimed that its aims were giving more power to the country's indigenous and poor communities by means of land reforms and redistribution of gas wealth, and gradually increased its electoral support.

Evelyn Rose Matthei Fornet (born November 11, 1953) is a Chilean economist and politician.

Matthei entered Chilean politics in the late '80s and early '90s, as part of the National Renewal party's youth group called Patrulla Juvenil ("Youth Patrol"), along the future President of Chile, Sebastián Piñera, and future fellow senator and minister, Andrés Allamand.

From 1990 to 1994 Matthei was deputy for District 23, and from 1994 to 1998, a deputy for District 15. Later, leaving National Renewal and entering the Independent Democrat Union, Matthei was elected senator in 1997, representing the Coquimbo Region, being re-elected in 2005. Matthei left her seat at the Senate in January 2011, when she was designated Ministry of Labor and Social Providence by President Sebastián Piñera.

Matthei holds a bachelor's degree in business administration from the Pontificia Universidad Católica de Chile. She is the daughter of retired Air Force General and member of the military junta that ruled Chile from 1973 to 1990, Fernando Matthei and Elda Fornet. She is married to fellow economist and former Chilean Central Bank Deputy Governor Jorge Desormeaux.

Verónica Michelle Bachelet Jeria (Spanish pronunciation: [miˈtʃel vatʃeˈlet]; born September 29, 1951) is a Social Democrat politician who was President of Chile from 11 March 2006 to 11 March 2010. She was the first female president of her country. In September 2010 Bachelet was appointed as the head of UN Women by UN Secretary-General Ban Ki-moon.

Bachelet won the 2006 presidential election in a runoff, beating center-right businessman and former senator Sebastián Piñera (who eventually succeeded Bachelet as President) with 53.5% of the vote. She campaigned on a platform of continuing Chile's free-market policies, while increasing social benefits to help reduce the gap between rich and poor.

Bachelet, a pediatrician and epidemiologist with studies in military strategy, served as Health Minister and Defense Minister under her predecessor, President Ricardo Lagos. She is a separated mother of three and describes herself as an agnostic. As well as her native Spanish, she speaks English, German, Portuguese and French, with varying levels of fluency.

David Rockefeller, Sr. (born June 12, 1915) is the current patriarch of the Rockefeller family. He is the youngest and only surviving child of John D. Rockefeller, Jr. and Abby Aldrich Rockefeller, and the only surviving grandchild of oil tycoon John D. Rockefeller, founder of Standard Oil. His five siblings were Abby, John D. III, Nelson, Laurance and Winthrop.

Rockefeller was born in New York City and grew up in a nine-story mansion at 10 West 54th Street, the then-largest private residence in the city. The home contained rare, ancient, medieval and Renaissance treasures collected by his father — with some, such as the Unicorn Tapestries, held in an adjoining building at 12 West 54th Street. On the seventh floor was his mother Abby's private modern art gallery. The mansion was subsequently donated by David's father as a site for the sculpture garden in his wife's name and memory, now part of the complex that is the Museum of Modern Art.

He spent much time as a child at the vast family estate of Pocantico (see Kykuit), where, in his memoirs, he recalls visits by powerful associates of his father, including General George C. Marshall, the adventurer Admiral Richard Byrd (whose Antarctic expeditions had been funded by the family), and the famous aviator Charles Lindbergh. Summer vacations were spent at the Eyrie, a vast 100-room mansion in Seal Harbor on the southeast shore of Mount Desert Island, in Maine. The mansion was demolished by the family in the early 1960s.
