Answer the question at the end by quoting:

Jean-Philippe Rameau (French: [Zafilip Ramo]; (1683-09-25)25 September 1683 - (1764-09-12)12 September 1764) was one of the most important French composers and music theorists of the 18th century. He replaced Jean-Baptiste Lully as the dominant composer of French opera and is also considered the leading French composer for the harpsichord of his time, alongside Francois Couperin. Little is known about Rameau's early years, and it was not until the 1720s that he won fame as a major theorist of music with his Treatise on Harmony (1722) and also in the following years as a composer of masterpieces for the harpsichord, which circulated throughout Europe.
Along with Francois Couperin, Rameau is one of the two masters of the French school of harpsichord music in the 18th century. Both composers made a decisive break with the style of the first generation of harpsichordists, who confined their compositions to the relatively fixed mould of the classical suite. This reached its apogee in the first decade of the 18th century with successive collections of pieces by Louis Marchand, Gaspard Le Roux, Louis-Nicolas Clerambault, Jean-Francois Dandrieu, Elisabeth Jacquet de la Guerre, Charles Dieupart, and Nicolas Siret.  Rameau and Couperin have different styles. They seem not to have known one another (Couperin was one of the official court musicians while Rameau was still an unknown; fame would only come to him after Couperin's death). Rameau published his first book of harpsichord pieces in 1706 while Couperin (who was fifteen years his senior) waited until 1713 before publishing his first "ordres." Rameau's music includes pieces in the pure tradition of the French suite: imitative ("Le rappel des oiseaux," "La poule") and character ("Les tendres plaintes", "L'entretien des Muses") pieces and works of pure virtuosity that resemble Scarlatti ("Les tourbillons," "Les trois mains") as well as pieces that reveal the experiments of a theorist and musical innovator ("L'Enharmonique", "Les Cyclopes"), which had a marked influence on Daquin, Royer, and Jacques Duphly. The suites are grouped in the traditional way, by key.  Rameau's three collections appeared in 1706, 1724 and 1726 or 1727, respectively. After this, he only composed a single piece for the harpsichord: "La Dauphine" (1747). Other works, such as "Les petits marteaux," have been doubtfully attributed to him.  During his semiretirement in the years 1740 to 1744, he wrote the Pieces de clavecin en concert (1741), which some musicologists consider the pinnacle of French Baroque chamber music. Adopting a formula successfully employed by Mondonville a few years earlier, these pieces differ from trio sonatas in that the harpsichord is not simply there as basso continuo to accompany other instruments (the violin, flute or viol) playing the melody but has an equal part in the "concert" with them. Rameau also claimed that the pieces would be equally satisfying as solo harpsichord works--although this statement is far from convincing, since the composer took the trouble to transcribe five of them himself--those where the lack of other instruments would show the least.

What were some of his pieces?

IN: Henry David Thoreau (see name pronunciation; July 12, 1817 - May 6, 1862) was an American essayist, poet, philosopher, abolitionist, naturalist, tax resister, development critic, surveyor, and historian. A leading transcendentalist, Thoreau is best known for his book Walden, a reflection upon simple living in natural surroundings, and his essay "Civil Disobedience" (originally published as "Resistance to Civil Government"), an argument for disobedience to an unjust state. Thoreau's books, articles, essays, journals, and poetry amount to more than 20 volumes. Among his lasting contributions are his writings on natural history and philosophy, in which he anticipated the methods and findings of ecology and environmental history, two sources of modern-day environmentalism.

Thoreau contracted tuberculosis in 1835 and suffered from it sporadically afterwards. In 1860, following a late-night excursion to count the rings of tree stumps during a rainstorm, he became ill with bronchitis. His health declined, with brief periods of remission, and he eventually became bedridden. Recognizing the terminal nature of his disease, Thoreau spent his last years revising and editing his unpublished works, particularly The Maine Woods and Excursions, and petitioning publishers to print revised editions of A Week and Walden. He wrote letters and journal entries until he became too weak to continue. His friends were alarmed at his diminished appearance and were fascinated by his tranquil acceptance of death. When his aunt Louisa asked him in his last weeks if he had made his peace with God, Thoreau responded, "I did not know we had ever quarreled."  Aware he was dying, Thoreau's last words were "Now comes good sailing", followed by two lone words, "moose" and "Indian". He died on May 6, 1862, at age 44. Amos Bronson Alcott planned the service and read selections from Thoreau's works, and Channing presented a hymn. Emerson wrote the eulogy spoken at the funeral. Thoreau was buried in the Dunbar family plot; his remains and those of members of his immediate family were eventually moved to Sleepy Hollow Cemetery (42deg27'53''N 71deg20'32''W) in Concord, Massachusetts.  Thoreau's friend William Ellery Channing published his first biography, Thoreau the Poet-Naturalist, in 1873. Channing and another friend, Harrison Blake, edited some poems, essays, and journal entries for posthumous publication in the 1890s. Thoreau's journals, which he often mined for his published works but which remained largely unpublished at his death, were first published in 1906 and helped to build his modern reputation. A new, expanded edition of the journals is under way, published by Princeton University Press. Today, Thoreau is regarded as one of the foremost American writers, both for the modern clarity of his prose style and the prescience of his views on nature and politics. His memory is honored by the international Thoreau Society and his legacy honored by the Thoreau Institute at Walden Woods, established in 1998 in Lincoln, Massachusetts.
