Louis Marie DE SCHRYVER
Born in Paris in 1862, Louis-Marie De Schryver grew up in an intellectual environment. His father was a well-known journalist. Louis-Marie's artistic talent was precocious. As early as 1876, at only 13 years old and self-taught, he exhibited two floral still-lifes at the Salon: Daisies and Chrysanthemums and Violets and Spring Flowers.
The following year, he entered the studio of Philippe Rousseau (1816-1887), a painter of landscapes and genre scenes, and continued to exhibit at the Salon while completing his training with him. In 1879, he won a bronze medal at the Sydney World's Fair with his painting The Lilacs. In 1886, he took a studio in Paris and specialized in the representation of scenes of daily life, often including a flower seller and her customers.
This theme, which he used over and over again, enabled him to achieve international recognition and financial prosperity. In 1888, he became a member of the Society of French Artists. In 1891, he joined the studio of the orientalist painter and portraitist Gabriel Ferrier (1847-1914) who was then a renowned teacher. He thus completed his training, before asserting himself in the art of portraiture.
At the 1900 Universal Exhibition in Paris, he was awarded a gold medal.
That same year, he bought a house in Neuilly and settled there.
At the beginning of the 20th century, he turned to painting car races and developed his style towards impressionism. However, as this theme and style did not meet with the expected commercial success, De Schryver returned to his favorite themes: portraits, still-lifes and scenes of Parisian life.
After the First World War, from 1919 to 1925, he travelled to the occupied Rhineland to paint landscapes.
He continued to exhibit sporadically at the Salon during the interwar period. He died at Neuilly on December 6, 1942 at the age of 80.
