Born in Montfort sur Riste, Eure on 1st February 1849.
Lebourg first trained as an architect studying under Drouin at the École Municipale de Dessin inRouen. Whilst studying architecture Lebourg became increasingly interested in art and it was through Drouin that he met the artist Victor Delamarre.
Lebourg soon gave up his studies in architecture and started to attend the École Municipale de Peinture and Dessin in Rouen studying under Gustave Morin.
In 1872 he was elected to the École des Beaux Arts of Rouen and then to that ofParis. He left for Algeria where he was appointed Professor of Drawing at the École des Beaux Arts (1872-1876). In Africa he devoted himself to landscapes – painted in the fresh air.
Back in Paris he worked with Jean Paul Laurens but quickly joined the impressionists. Taking part twice in their exhibitions in 1879 and 1880.
In 1883 and in 1886 he exhibited in the Salon de la Société des artists Français. After the foundation of the Société National des Beaux Arts in 1889 Lebourg became a regular exhibitor between 1891 and 1914.
He painted views of Paris and its many districts as well as Rouen. These scenes are characterized by their brightness and tranquility. Where forms are dissolved by the effects of sunlight and mist. There is a habitual presence of water in his work as is represented in such works as Snow in the Avergne (1886).
Lebourg during his life lived and worked in many different places, spending time in the Netherlands(1895-1897) and a spell in Britain where he developed a love of Turner, Constable and Gainsborough.
