Edvard Hagerup Grieg /ˈɛdʋɑɖ ˈhɑːgəɾʉːp gɾiːg/ (15 June 1843 – 4 September 1907) was a Norwegian composer and pianist. He is best known for his Piano Concerto in A minor, for his incidental music to Henrik Ibsen's play Peer Gynt (which includes Morning Mood and In the Hall of the Mountain King), and for his collection of piano miniatures Lyric Pieces.

Edvard Hagerup Grieg was born in Bergen, Norway on 15 June 1843. His parents were Alexander Grieg (1806–1875), a merchant and vice consul in Bergen, and Gesine Judithe Hagerup (1814–1875), a music teacher and daughter of Edvard Hagerup. The family name, originally spelled Greig, has Scottish origins. After the Battle of Culloden in 1746, Grieg's great-grandfather traveled widely, settling in Norway about 1770, and establishing business interests in Bergen.

Edvard Grieg was raised in a musical area. His mother was his first piano teacher and taught him to play at the age of 6. Grieg studied in several schools,^{[clarification needed]} including Tank's School. He often brought in samples of his music to class.^{[citation needed]}

Edgar Allan Poe (born Edgar Poe; January 19, 1809 – October 7, 1849) was an American author, poet, editor and literary critic, considered part of the American Romantic Movement. Best known for his tales of mystery and the macabre, Poe was one of the earliest American practitioners of the short story and is considered the inventor of the detective fiction genre. He is further credited with contributing to the emerging genre of science fiction. He was the first well-known American writer to try to earn a living through writing alone, resulting in a financially difficult life and career.

He was born as Edgar Poe in Boston, Massachusetts; he was orphaned young when his mother died shortly after his father abandoned the family. Poe was taken in by John and Frances Allan, of Richmond, Virginia, but they never formally adopted him. He attended the University of Virginia for one semester but left due to lack of money. After enlisting in the Army and later failing as an officer's cadet at West Point, Poe parted ways with the Allans. His publishing career began humbly, with an anonymous collection of poems, Tamerlane and Other Poems (1827), credited only to "a Bostonian".

Jean-Pierre Boyer (possibly 15 February 1776 – 9 July 1850), a native of Saint-Domingue, was a soldier, one of the leaders of the Haitian Revolution, and President of Haiti from 1818 to 1843. He reunited the north and south of Haiti in 1820 and also invaded and took control of Santo Domingo, which brought all of Hispaniola under one government by 1822. Boyer managed to rule for the longest period of time of any of the revolutionary leaders of his generation.

Born a free gens de couleur (or mulatto) in Saint-Domingue (modern-day Haiti) and educated in France, Boyer fought with Toussaint Louverture in the early years of the Haitian Revolution. He allied himself with André Rigaud, also a mulatto, in the latter's abortive insurrection against Toussaint to try to keep control in the south of Saint-Domingue.

After going into exile in France, Boyer and Alexandre Pétion, another mulatto, returned in 1802 with the French troops led by General Charles Leclerc. After it became clear the French were going to try to reimpose slavery and restrictions on free gens de couleur, Boyer joined the patriots under Pétion and Jean-Jacques Dessalines, who led the colony to independence. After Pétion rose to power in the State of Haiti in the South, he chose Boyer as his successor.
