In 1948, French painter Michel Thompson (1921-2007) helped form the artistic group known as L'Homme-Témoin (Man as Witness). The group was comprised mostly of young French artists who chose to promote a style of expressive Social Realism in opposition to the prevailing taste for abstraction. They felt that abstractionists had lost touch with ordinary life and believed that beauty and sacredness existed in the simple things of everyday life. Thompson in turn, was able to capture the essence of those everyday scenes with remarkable "simplicity".
