There are various arguments as to why Freddie Prinze described his ethnic background the way he did. Prinze was born and raised in the Hispanic milieu of the Washington Heights section of New York City, a working poor, multi-ethnic neighborhood on the Upper West Side. His father, Karl, was a German immigrant from post-Nazi Germany, who worked as a tool and die maker and his mother, Maria, was a Puerto Rican factory worker. Some sources, including Freddie's own biography (as told by his mother), say his father was a Hungarian Jew. Freddie's death certificate does not support this allegation, listing his father as being born in Germany. Playing on the name "Nuyorican," as many New York Puerto Ricans identify themselves, Freddie described himself as "Hungarican," although he considered himself to be Puerto Rican.
