Christian Hundertmark (C100, b. 1974) is an artist and creative director based in Munich, Germany.

His first sketches, Anarchy and Bat Man, created in 1989, sparked a career as an active graffiti writer that lasted more than a decade. After completing his graphic design studies in 1999, Christian turned his attention to street art, becoming one of the pioneers of the then-emerging movement in Germany.

During this period, he became part of the international urban art scene and realised projects in London, Barcelona, Madrid and Milan. Since then, he has continued to develop a wide range of art projects and exhibitions. His work has appeared in numerous publications and has been exhibited in galleries and museums around the world.

Christian’s works are best described as compositions of hard-edged, floating layers. Their elements explore movement, masking and the balance between calm and tension. They often reflect both his graffiti and graphic-design background, while the painted forms are influenced by the transitions and contours of skateparks—an enduring reference to his youth as an avid BMX rider and skateboarder in the 1980s.

Christian also runs the graphic-design bureau C100 Studio. He is the author of the bestselling The Art of Rebellion series—I, II, III and IV—published in 2003, 2005, 2010 and 2016. With more than 80,000 copies sold worldwide, the books are widely regarded as essential references on street art.

Since 2016, Christian has also formed the artist duo Layer Cake with fellow artist Patrick Hartl. Together, they published The Art of Writing Your Name: Urban Calligraphy and Beyond in 2017.
