Jasper Francis Cropsey was an American landscape artist of the Hudson River School.
He was born in Rossville on Staten Island, New York.

When he was a child, Cropsey had recurring periods of poor health. While absent from school, he taught himself to draw. His early drawings included architectural sketches and landscapes. After studying architecture for five years, he turned his attention to landscape painting, under the instruction of Edward Maury. He visited England, France, Switzerland, and Italy in 1847, went abroad again in 1855, and resided seven years in London, sending his pictures to the Royal Academy and to the International exhibition of 1862.

Trained as an architect, he set up his own office in 1843. Cropsey studied watercolor and life drawing at the National Academy of Design and first exhibited there in 1844. A year later he was elected an associate member and turned exclusively to landscape painting in the 1840s, shortly after he was featured in an exhibition entitled "Italian Compositions."
Cropsey traveled in Europe from 1847-1849, was elected a full member of the Academy in 1851, and lived in England 1856-1863. During this time he specialized in autumnal landscape paintings of the northeastern United States, often idealized and with vivid colors.
He co-founded, with ten fellow artists, the American Society of Painters in Water Colors in 1866.

Cropsey's interest in architecture continued throughout his life and was a strong influence in his painting, most evident in his precise arrangement and outline of forms. But Cropsey was best known for his lavish use of color and, as a first-generation member from the Hudson River School, painted autumn landscapes that startled viewers with their boldness and brilliance. As an artist, he believed landscapes were the highest art form and that nature was a direct manifestation of God.

Jasper Cropsey died in anonymity but was rediscovered by galleries and collectors in the 1960s.
