Armand Rassenfosse was born in Liège on August 6th, 1862. He was an autodidact Belgian graphic artist, book illustrator and painter. His masterwork was a series of illustrations for Charles Baudelaire's 'Les Fleurs du mal'.

Together with Félicien Rops, the 'Ropsenfosse'-technique came into development. This different take on varnishing meant a real development of the art of engraving.

Rassenfosse was known to be working with the Bénard printing house, and he created a large number of posters. By the time his career ended, Rassenfosse turned to painting himself. Lone and vulnerable women could be counted among his subjects of preference, although he took great joy in depicting different aspects of his personal life as well.

Rassenfosse passed away on January 28th, 1934.
