Marko Feingold was born in Besztercebánya (Neusohl in German), Austria-Hungary, today Banská Bystrica, Slovakia.

After he had trained in business, he found work in Vienna, became unemployed and travelled with his brother, Ernst, in Italy.

[2] At that time he was initially a member of the SPÖ, but later left the party due to its particularly anti-Semitic orientation influenced by Karl Renner.

[3] As one of the oldest contemporary witnesses, Feingold explicitly commented in 2013 and 2018 in the media on Karl Renner's support for the Anschluss and anti-Semitism.

Feingold also criticized the social democrats in this context and said that after 1945, after a complaint by the party secretary of the SPÖ, he was chased out with the words Saujud, verschwind!).
