Born 1909, Warneton, Belgium. Died 1984 in Paris.
Singier became a naturalised Frenchman in 1919 and studied at the Boulle School of Art and Design in Paris in 1926-27. He became an exhibitor at many of the Paris salons and at the Galerie de Paris throughout the 1950s and 1960s. In 1945 he was one of the founding members of the Salon de Mai and was partly credited with the discovery of Kandinsky and Mondrian and the promotion more widely of abstract art at that time.
As well as his non-figurative painting and lithography, his practice included mural painting, mosaic, theatre design and tapestry (for Aubusson, Beauvais and Gobelins). From 1951-1954 he taught at Ranson Academy and later at the Paris School of Art from 1967 -1978.
