Christian Kruck was born in Hamburg in 1925. After training as a lithographer, Kruck began his studies at the Academy of Visual Arts in Nuremberg in 1942 but later moved to Freibourg, where he completed his education in 1950. He then moved back to Hamburg.
After his first extensive trip to Italy, Christian Kruck was given a position at the Städel school in Frankfurt am Main in 1953. Kruck developed his own process for his color lithographs, which gave his prints a watercolor-like character. He portrayed mainly landscapes, in which he focused, not on the actual scenic details, but on the reflection and effect of that which is seen by and experienced in the landscape of the soul.
Christian Kruck spent more and more time on longer trips to Italy before he was appointed to a teaching position at the Pratt Graphic Arts Center in New York. In 1970, the artist returned to Frankfurt am Main to lecture on print graphics at the Städel school. Christian Kruck was awarded the Senefelder Foundation Prize in 1975 and the Daniel Henry Kahnweiler Prize in 1983.
Christian Kruck died in 1985 in Frankfurt.
