However what really distinguishes him, is his constant discretion, the sensitivity of his inspiration, his liking of peaceful landscapes. There always was in his work a great humility in his attempt to retranscribe on the canvas the enchantment which he felt in front of real situations and landscapes.
He takes there an always intact pleasure to paint in the open air and in any season the landscapes of this area.
The following year Sisley applied for French citizenship, but was refused. A second application was made and supported by a police report, but illness intervened,  and Sisley remained a British national until his death.
He died on 29 January 1899 of throat cancer in Moret-sur-Loing at the age of 59, a few months after the death of his wife. His body was buried with that of his wife at Moret-sur-Loing Cemetery. 
Impressionist landscape painter, born in Paris of expatriate English parents (but had a French grandmother). Was sent to London for four years to prepare for a commercial career. Then turned to painting and in 1862 entered the studio of Gleyre, where he met Renoir, Monet and Bazille. He and his friends left about five months later and began to paint out of doors, directly from nature, in the region of Paris and in the Forest of Fontainebleau. Exhibited with the Impressionists in 1874, 1876, 1877 and 1882, and had his first one-man exhibition at La Vie Moderne, Paris, in 1883. After working at Louveciennes, Marly-le-Roi, Sèvres and elsewhere on the outskirts of Paris, he settled in 1880 near Moret-sur-Loing, and painted there most of his late works. Also worked in Britain in 1874 (especially around Hampton Court) and 1897 (the coast near Cardiff). He received little recognition in his lifetime and from 1871, when his father was no longer able to support him, spent much of his life in poverty. Died at Moret-sur-Loing.
Alfred Sisley ( ; French: [sislɛ] ; 30 October 1839 – 29 January 1899) was an Impressionist landscape painter who was born and spent most of his life in France, but retained British citizenship. He was the most consistent of the Impressionists in his dedication to painting landscape en plein air (i.e., outdoors). He deviated into figure painting only rarely and, unlike Renoir and Pissarro, found that Impressionism fulfilled his artistic needs.
Alfred Sisley, (born Oct. 30, 1839, Paris, France—died Jan. 29, 1899, Moret-sur-Loing), painter who was one of the creators of French Impressionism.
Although his wealthy English parents had originally intended him for commerce, Sisley began painting as an amateur, and in Charles Gleyre’s studio in 1862 he began his association with Claude Monet, Pierre-Auguste Renoir, and Jean-Frédéric Bazille. The Franco-German War of 1870–71 brought financial ruin to the Sisley family and caused Sisley to flee temporarily to London. At this period of crisis he decided to make painting his full-time career. The rest of his life was a constant struggle against poverty. Shortly after his death his talent began to be widely recognized, and the price of his work rose sharply.
In 1857, at the age of 18, Sisley was sent to London to study for a career in business, but he abandoned it after four years and returned to Paris in 1861. From 1862, he studied at the Paris École des Beaux-Arts within the atelier of Swiss artist Marc-Charles-Gabriel Gleyre, where he became acquainted with Frédéric Bazille, Claude Monet and Pierre-Auguste Renoir. Together they would paint landscapes en plein air rather than in the studio, in order to capture the transient effects of sunlight realistically. This approach, innovative at the time, resulted in paintings more colourful and more broadly painted than the public was accustomed to seeing. Consequently, Sisley and his friends initially had few opportunities to exhibit or sell their work. Their works were usually rejected by the jury of the most important art exhibition in France, the annual Salon. During the 1860s, though, Sisley was in a better financial position than some of his fellow artists, as he received an allowance from his father.
