Karl Hagedorn was always interested in one theme: Man and machine. "In the early USA paintings of Karl Hagedorn, there appear, at first sparingly and later on in increasing numbers technical components - fragmnets of machinery, graphic elements, traffic and sign symbols. The more the human figure becomes abstract and geometrical, almost robot-like, the more the abstract parts become humanized, softer and more supple, as if they wished increasingly to assume a human nature."
(Wolfgang Horn - Hagedorn,1998)
