Realism and Romanticism ofearly 19th century gave way to Impressionism and PostImpressionism inlater half ofcentury, with Paris beingdominant art capital ofworld. InUnited StatesHudson River School was prominent. 19th century painters included: |
Onliterary frontnew century opens with romanticism, a movement that spread throughout Europe in reaction to 18thcentury rationalism, and it develops more or less alonglines ofIndustrial Revolution, with a design to react againstdramatic changes wrought on nature bysteam engine andrailway. William Wordsworth and Samuel Taylor Coleridge are consideredinitiators ofnew school in England, while incontinentGerman Sturm und Drang spreads its influence as far as Italy and Spain. |
French arts had been hampered byNapoleonic Wars but subsequently developed rapidly. Modernism began. |
Goncourts and Emile Zola in France and Giovanni Verga in Italy produce some offinest naturalist novels. Italian naturalist novels are especially important in that they give a social map ofnew unified Italy to a people that until then had been scarcely aware of its ethnic and cultural diversity. On February 21, 1848, Karl Marx and Friedrich Engels publishedCommunist Manifesto. |
There was a huge literary output during19th century. Some ofmost famous writers includedRussians Leo Tolstoy, Anton Chekhov and Fyodor Dostoevsky;English Charles Dickens, John Keats, Alfred, Lord Tennyson and Jane Austen;Scottish Sir Walter Scott;Irish Oscar Wilde;Americans Edgar Allan Poe, Ralph Waldo Emerson, and Mark Twain; andFrench Victor Hugo, Honoré de Balzac, Jules Verne and Charles Baudelaire. Some other important writers of note included: |
Sonata form matured duringClassical era to becomeprimary form of instrumental compositions throughout19th century. Much ofmusic from19th century was referred to as being inRomantic style. Many great composers lived through this era such as Ludwig van Beethoven, Franz Liszt, Frédéric Chopin, Piotr Ilyich Tchaikovsky and Richard Wagner.list includes: |
19th century sawbirth of science as a profession;term scientist was coined in 1833 by William Whewell.[9] Amongmost influential ideas of19th century were those of Charles Darwin, who in 1859 publishedbookOrigin of Species, which introducedidea of evolution by natural selection. Louis Pasteur madefirst vaccine against rabies, and also made many discoveries infield of chemistry, includingasymmetry of crystals. Thomas Alva Edison gaveworld a practical everyday lightbulb. Karl Weierstrass and other mathematicians also carried outarithmetization of analysis for functions of real and complex variables; they also beganuse of hypercomplex numbers. Butmost important step in science at this time wasideas formulated by Michael Faraday and James Clerk Maxwell. Their work changedface of physics and made possible for new World to come about.
