Francis Gruber was a painter connected with the movement known as Miserablilisme, current during the 1940s and 1950s. At the 'Salon de la Liberation', the first Salon d'Automne held in Paris in 1944 after the liberation of Paris, he exhibited the Job (London, tate) which symbolized in its colour and dejection the sufferings of Europe during the years 1939-44.
His interest in straightforward figurative art make this, and others such as the Artist's Studio, as well as works by fellow Miserabilistes such as Buffet, the antithesis of the hermetic imagery and distortions of Picasso at the same period, and an attempt to break away from the artistic language of what was then considered as the bygone age.
Gruber was a friend of Friesz and Giacometti.
His life was gravely affected and eventually shortened by asthma.
