In 1907, Bombois fulfilled his dream of moving to Paris, where he married and worked as a railway laborer, eventually finding a night job at a newspaper printing plant handling heavy newsprint rolls.
1914 marked the beginning of four-and-a-half years of military service in World War I. Bombois spent much of it on the front line, earning three decorations for bravery.
The paintings of his maturity are bold in color, featuring strong contrasts of black, bright reds, blues and electric pinks.
His paintings of women are emphatic in their carnality,[1] and his landscapes are notable in their careful attention to space, and to the effects of reflected light on water.
In 2023, Bavarian town of Passau in Germany restituted a painting by Bombois that had been looted from Jewish collector Marcel Joseph Monteux, who was murdered in Auschwitz-Birkenau on August 15, 1944.
