During his stay in Düsseldorf, the racialist, right-wing journalist Lothrop Stoddard described Florian thus: "He was a distinctly sinister-looking type. Hard-faced, with a cruel eye and a still crueler mouth.
A sadist, if I ever saw one.
I can imagine how unpopular he must be among the good-natured, kindly Duesseldorfers.""
Florian was sentenced to six years in prison after the war because of his rank in the Nazi Party and released in 1951. He remained a convinced Nazi after the war and maintained contact to former associates from the Nazi era. He was charged with ordering the execution of five Düsseldorf citizens who had attempted to surrender the city to the United States Army in April 1945 but was acquitted.
