Marcus Jansen was born 1968 in Manhattan, New York City. He’s been referred to as a cartographer of conflict and “One of the most Important American Painters of our time” by two time Documenta Kassel curator and renowned art critic Prof Dr Manfred Schneckenburger.

Jansen’s works have been exhibited at the La Triennale Di Milano Museum, Milan Italy, 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. Jansen joined the US Armed Forces in 1989 and was immediately sent to Desert Storm. After his military discharge, Jansen was diagnosed with PTSD and had difficulties holding a regular job. 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.
Jansen's first major International book titled, “Marcus Jansen - DECADE” was published by the leading art book publisher SKIRA Editore, Italy. The book features a foreword by notorious London Art Dealer, Steve Lazarides, as well as historic perspectives and critic texts.His first European solo museum exhibition held at the Triennale di Milano Museum was titled after his book “Marcus Jansen DECADE”. Critics hailed this show as among the top 10 shows to see in Italy. This exhibition was accompanied by the award winning documentary film titled, "Marcus Jansen - Examine & Report". The film by Emmy award winning Filmmaker John Scoular spotlights Marcus Jansen, recounting events that activated the start of his artistic career and dissecting his motivation for painting while examining the direction of his socio-politically influenced urban landscapes. The film is to be released to the public in 2017.

Following this, a string of exhibitions in Germany, including at Kallmann Museum, Ismaning by Munich, produced texts by leading newspapers and magazines. Dr. Dieter Ronte: "In my museum career, one should always remain objective. But for this exhibition, I can only say: it touches me unbelievably. I find it sensational. And it's terrific that Marcus Jansen is again present in Germany."

Jansen’s most recent International monograph, titled "Marcus Jansen AFTERMATH", was published by Hirmer Verlag Munich and holds text by renowned two time curator of the Documenta and art critic, Dr. Manfred Schneckenburger and Germany’s senior art critic at the Suddeutsche Zeitung, Dr. Gottfried Knapp. It also contains a foreword by Art Historian Dr. Dieter Ronte, the Former Museum Director of the Kunst Museum in Bonn and Dr. Elmar Zorn, curator of Jansen’s European tour. The first U.S. and German solo Museum exhibitions will be held in 2018 at the Baker Museum in Naples Florida and at the Zitadelle Museum in Berlin in 2018.
