Inspired by
pioneers like John Constable (1776 - 1837) and Richard Parkes Bonington (1802 - 28) from the school
of English landscape
painting, as well as Theodore Rousseau (1812 - 67) and Jean - Francois Millet (1814 - 75), and initially linked with the Naturalist and Realist movements, which were themselves a reaction to the social changes caused by the Industrial Revolution, the principles
of plein -
air art later formed the core
of Impressionism - specifically Impressionist landscape
painting - as practised by Monet (1840 - 1926) during the last 30 years
of the century.
