Josef Floch was born on November 5, 1894 in Vienna. He studied at the Vienna Academy and starting from 1919 he became a member of the Hagenbund, where he exhibited frequently. Floch moved to Paris in 1925, where he quickly established himself thanks to his friend Willy Eisenschitz. He exhibited in the prestigious gallery of Berthe Weill, which also oversaw Picasso and Modigliani. Numerous exhibitions and awards documented his success in New York.
Most of his pictures have no actions, but describe states and relations of human coexistence. In his landscapes mainly dominate blunt earthy tones, with around 1950 new color chords vigorously and largely saturated hues determine the painting. His travels took him from Palestine to Paris and finally to New York, where he died in 1977.
