Franziska "Fanny" Braun (Kronberger)

In the book "The lost life of Eva Braun" of Angela Lambert, Franzizka's maiden surname was Kronburger - this is probably misprint.

Born in Munich, Eva Braun was the second daughter of school teacher Friedrich "Fritz" Braun and Franziska "Fanny" Kronberger, who had worked as a seamstress before her marriage.Her elder sister, Ilse, was born in 1909 and her younger sister, Margarete (Gretl), was born in 1915. Braun's parents were divorced in April 1921, but remarried in November 1922, probably for financial reasons (hyperinflation was plaguing the German economy at the time). Braun was educated at a Catholic lyceum in Munich, and then for one year at a business school in the Convent of the English Sisters in Simbach am Inn, where she had average grades and a talent for athletics. At age 17 she took a job working for Heinrich Hoffmann, the official photographer for the Nazi Party (NSDAP). She met Hitler, 23 years her senior, at Hoffmann's studio in Munich in October 1929. He had been introduced to her as "Herr Wolff".Eva's sister, Gretl, also worked for Hoffman from 1932 onward, and the women rented an apartment together for a time. Gretl accompanied her sister on her later trips with Hitler to the Obersalzberg.
