"Simon Berger moved to Bratislava (Pressburg), Slovakia because he was unable to receive a marriage license in Austria. He was a 2nd son and only 1st-born sons were given marriage licenses. Simon & his son Heinrich Berger moved to Vienna (Austria) where Heinrich had to register as a servant in the household of a licensed banker because he could not get a permit to stay in Vienna unless he occupied a servant’s job. Heinrich and his parents had moved to Vienna in 1848 (the year of the revolution); in 1850, father and son opened a licensed wholesale firm under the name of "S. Berger & Son," becoming members of the Chamber of Commerce (Wholesale Division). They dealt with India, importing indigo (a plant yielding a violet-blue dyestuff). At first the firm was located at Vienna, Muenzerstrasse 686, but moved to Gonzagagasse 5 in 1860, where they lived and also had their place of business. Both had to pay Jew Tax up to 1864. Heinrich's eldest son Theodor Berger took over his father’s firm when Heinrich died early from TB, leaving his wife $7 million dollars. Son Ernst became a painter and switched later to the theory of painting. He wrote a two volume treatise, his name is still world-renowned in his field."
