Braun was the youngest of Eva's two sisters. Gretl spent much time with Eva at Hitler's Berghof, where she enlivened the atmosphere by having fun, smoking, and flirting with the orderlies. According to Hitler's secretary, Traudl Junge, Hitler explained to her at length why he detested smoking, but she would not give up the habit. On 3 June 1944 she married SS-Gruppenführer Hermann Fegelein, who served as Reichsführer-SS Heinrich Himmler's liaison officer on Hitler's staff. Their wedding took place at the Mirabell Palace in Salzburg with Hitler, Himmler, and Martin Bormann as witnesses.
