Marcus Jansen was born 1968 in Manhattan New York City, referred to as a cartographer of conflict and recently noted as “One of the most Important American Painters of his generation” by Documenta Kassel curator 1977 and 1987 Prof Dr Manfred Schneckenburger in Munich Germany.

His collections include the Moscow Museum of Modern Art (MMOMA), The New Britain Museum of American Art, The PERMM Museum of Contemporary Art, the Kallmann Museum, The National Taiwan Museum of Fine Art, and the Smithsonian Institution in Washington DC.  

Son of a west-indien mother and German father, Jansen was first influenced by a rebellious Graffiti art movement from New York in the 1980’s. A former soldier, Jansen was discovered and mentored by former Museum Director and Art Historian Jerome A. Donson, (Director of the American Vanguard Exhibitions Europe 1961 MOMA New York), who curated exhibitions with artists like Jackson Pollock, Robert Rauschenberg, Jasper Johns, Willem de Kooning and Franz Kline. Donson referred to Jansen's work as being "reminiscent of the Ash-Can School” and named him  the “innovator” of modern expressionism in Jansen’s French published catalog in 2005. 

Jansen was raised between New York City and Moenchengladbach Germany where he studied briefly at the Kunstgewerbe Schule the Berufsfachschule fuer Gestaltung and completed a three year apprenticeship as a commercial house painter (Maler), where he was first introduced to his current medium of choice, oil enamels. He joined the US Armed Forces in 1989 and was immediately sent to Desert Storm. After his military discharge, Jansen was diagnosed with Post Traumatic Stress, he started selling paintings on the streets of New York between Prince Street and Broadway as part of the group  “Prince Street Kings”, transforming to a professional painter.
