Early years 
Born in Wiesbaden and educated in his hometown and Berlin, he volunteered for the German Imperial Army in 1915, serving on the Western Front and at Isonzo in Italy. Briefly involved with communism after his 1919 demobilization he soon took part in skirmishes against the Spartacist League before settling into various low-level white-collar jobs.
Nazi leader 
Habicht joined the Nazi Party in 1926 and established a number of local journals for the group, whilst also serving as a member of the Hesse-Nassau assembly and the leader of the Nazis on Wiesbaden council. By 1931 he had also been elected to the Reichstag for Nassau and theoretically retained this position until 1938.
Under orders from Adolf Hitler he was sent to Austria in 1931 as Landesinspekteur to oversee the reorganization of the Nazi Party in the country, and before long he was the effective leader of the group, despite official control resting with Alfred Proksch. Under Habicht the Nazis experienced growth, mostly at the expense of the Heimwehr, many of whose members switched over to Nazism.Initially Engelbert Dollfuß attempted a conciliation, notably offering Habicht two Nazi cabinet seats, before trying to get Italy to exert pressure on Hitler to restrain Habicht's anti-government activities. Habicht was deported in 1933 after the Austrian government finally decided to ban the Nazi Party outright. In response Habicht set up a leadership-in-exile in Munich which directed a campaign of terror against the Dollfuß regime which culminated in a failed coup attempt in the murder of Dollfuß in July 1934. An unpopular figure with many of the Austrians, he was excluded from the country after this failure as Hitler placed the blame on Habicht, who had been responsible for determining the details of the coup attempt.
Severely discredited by the failure, Habicht went into seclusion in the Harz mountains before being allowed to take up the post of mayor of Wittenberg in 1937. His reputation partially restored, Habicht returned to a more important role in the Nazi Party in 1939 when he was appointed Undersecretary in the Foreign Department of the Nazi Party. As part of his duties he was sent to Norway in 1940 to investigate the organization of government in the newly occupied territory and he called for the removal of the Vidkun Quisling government and its replacement with an administrative council. Initially he had hoped to give any regime more legitimacy by placing the popular Paal Berg at its head rather than the minor figure of Quisling, although Berg rejected any such settlement.However, when his plans were rejected by Johan Nygaardsvold and Haakon VII of Norway Hitler once again lost faith in Habicht and ordered him into the Wehrmacht. He spent the remainder of his life on the Eastern Front and died in action there at Nevel.
