Bram Bogart ranks amongst the principal artists of the ‘Informel’, the large post-war movement which abandoned geometric abstraction in favour of a more intuitive form of expression, similar to action painting, but often a lot more textural. Bogart worked at the heart of the movement, which included artists such as Alberto Burri in Italy and Antonio Tàpies in Spain. During 1949, Bogart worked in Le Cannet where he rented the cellar of a guesthouse. Some African sculptures had been stored in the cellar and these inspired Bogart's Cubist works. At the end of 1950, Bogart explored native African signs and symbols which lead to his use of pure shapes: the circle, square and diamond.

From 1951-59, Bogart settled in Paris. painting delicate and subtle, yet strong gestural matter works. After his move to Belgium in 1959, Bogart’s work became widely recognised. His unmistakable original canvases were characterised by a new technique radiant with colour, light and optimism. Although Bogart has used the same technique since the early 1960s, he has always been able to renew his style and is considered a pioneer of post-war matter painting. Recently, Bogart's contribution to art history was further affirmed with an acquisition of a number of works by Tate Modern, London and a centenary retrospective at the Museum Prinsenhof in Delft.
