[1] Ittenbach began his art education as a student of Kaufmann, then left to study under Franz Katz [de] in Cologne.
In 1832, Ittenbach became a pupil, at the age of 19, of the Düsseldorf Academy, where he also received private lessons from its president, Schadow.
He would precede the execution of his greatest works with devout religious exercises, including confession and communion.
There is also a remarkable "Holy Family" dated 1861, painted for Prince Liechtenstein in his private chapel near Vienna.
Ittenbach was a popular painter in court circles, a member of most of the European academies, and the recipient of many medals and decorations.
