Frits Moritz mainly painted animals and hunting scenes, but he's also known for his genre scenes in impressionistic style.
He first trained as a graphic artist, after which he went to the art school in Düsseldorf.
Moritz worked from 1955 till 1960 in Brussels with his uncle who was a restorer for the Museum of Fine Arts in Brussels.
Fritz Moritz was inspired, in his own words, by the Düsseldorfer landscape painter Hugo Mühlig. This well known artist was famous for his impressionistic way of painting what also can be found in Moritz work.
