1895 he joined the team of the "Wiener Allgemeine Zeitung", where he initially worked as a reporter with the main focus of ‚court‘ and the ‚houses of Parliament‘.
With his feature articles and astute local and theater reviews, he developed into one of the most important representatives of the so-called Vienna coffeehouses literature.
Also 1908, Polgar's first book Der Quell des Übels und andere Geschichten (The Source of Evil and Other Stories) was published.
The place where Polgar frequented at this time was Café Central where he could be found in the company of Peter Altenberg, Anton Kuh, Adolf Loos and said Egon Friedell.
[6] After the Nazi regime came to power, there was no place for the “Austrian Jew and left-liberal anti-fascist Polgar in National Socialist Germany”, as Ulrich Weinzierl points.
After the Germans invaded France in June 1940, he fled to Marseille, from where in October 1940, with the help of the Emergency Rescue Committee, he managed to escape via the Pyrenees to Spain and via Lisbon to emigrate to the USA.
In 1951 Polgar received the Preis der Stadt Wien für Publizistik which has been awarded annually since 1951 and endowed with eight thousand Euros.
