Editing Georg Elser (section)

===The Bürgerbräukeller===
Elser arrived in Munich on 5 August 1939. Using his real name, he rented a room in the apartments of two unsuspecting couples, at first staying with the Baumanns and from 1 September, Alfons and Rosa Lehmann. He soon became a regular at the Bürgerbräukeller restaurant for his evening meal. As before, he was able to enter the adjoining Bürgerbräukeller Hall before the doors were locked at about 10:30&nbsp;p.m.<ref name="Gestapo Interrogation Report 1939"/>

Over the next two months, Elser stayed all night inside the Bürgerbräukeller 30 to 35 times. Working on the gallery level and using a flashlight dimmed with a blue handkerchief, he started by installing a secret door in the timber panelling to a pillar behind the speaker's rostrum. After removing the plaster behind the door, he hollowed out a chamber in the brickwork for his bomb. Normally completing his work around 2:00–3:00&nbsp;a.m., he dozed in the storeroom off the gallery until the doors were unlocked at about 6:30&nbsp;a.m. He then left via a rear door, often carrying a small suitcase filled with debris.<ref name="Gestapo Interrogation Report 1939"/>

Security was relatively lax at the Bürgerbräukeller. [[Christian Weber (SS general)|Christian Weber]], a veteran from the Beer Hall Putsch and the Munich city councillor, was responsible.<ref name="Hellmut G 2013"/> However, from the beginning of September, after the outbreak of war with Poland, Elser was aware of the presence of air raid wardens and two "free-running dogs" in the building.<ref name="Gestapo Interrogation Report 1939"/>

While he worked at night in the Bürgerbräukeller, Elser built his device during the day. He purchased extra parts, including sound insulation, from local hardware stores and became friends with the local master woodworker, Brög, who allowed him use of his workshop.<ref name="Gestapo Interrogation Report 1939"/>

On the nights of 1–2 November, Elser installed the explosives in the pillar. On 4–5 November, which were Saturday and Sunday dance nights, he had to buy a ticket and wait in the gallery until after 1&nbsp;a.m. before he could install the twin-clock mechanism that would trigger the detonator. To celebrate the completion of his work, Elser recalled later, "I left by the back road and went to the Isartorplatz where at the kiosk I drank two cups of coffee."<ref name="Gestapo Interrogation Report 1939"/>

On 6 November, Elser left [[Munich]] for [[Stuttgart]] to stay overnight with his sister, Maria Hirth, and her husband. Leaving them his tool boxes and baggage, he returned to Munich the next day for a final check. Arriving at the Bürgerbräukeller at 10&nbsp;p.m., he waited for an opportunity to open the bomb chamber and satisfy himself the clock mechanism was correctly set. The next morning he departed Munich by train for Friedrichshafen via [[Ulm]]. After a shave at a hairdresser, he took the 6:30&nbsp;p.m. steamer to [[Konstanz]].<ref name="Gestapo Interrogation Report 1939"/>
