Born in Wesel, in 1913 and 1914 Brautigam studied law in Grenoble, Oxford and Strasbourg. He fought in World War I and finished his studies in Münster in 1919. In 1920 he joined the Auswärtiges Amt. In 1922 he received his PhD and worked in various German embassies. In 1928 Bräutigam was sent to Moscow, where he met Alfred Rosenberg.
At the Nuremberg trials Bräutigam was not charged but acted as a witness against the prominent members of Nazi Germany. According to William L. Shirer. 13 pages Document from Berlin presented at the Nuremberg trails showed that Otto Bräutigam wrote several requests to integrate the local factions into the Wehrmacht. Starting by avoiding unnecessary cruelty against the local population. Brautigam said:” when we came to the east we found the people of east Europe, ready to be our partners in destroying Bolshevism we need to re-place our cards. Promise them something that guarantee their future…due to our cruel policies the Russian nationalist are uniting with the Bolsheviks against us”. “It did not take the population of the east long to recognize that, we are not there to destroy Bolshevism, but we are there to replace it”. Bräutigam's top secret report to his superiors in the fell on deaf ears. William L. Shirer described the report as Daring and Exceptional. "We now experience the grotesque spectacle that after the tremendous starvation of prisoners of war, millions of foreign laborers must be recruited to fill the gaps which have appeared in Germany. With the usual unlimited abuse of Slav people, "recruiting" methods were used which can only be compared with the blackest periods of the slave trade. We are interested in feeding them only insofar as they are still capable." Dr Otto Brautigam 25 October 1942 Goebbels and Himmler welcomed the idea by 1942. Pyotr Krasnov and Andrei Shkuro requested permission from Goebbels to fight along with Nazi Germany. They had mustered a Cossack force, largely from Soviet POWs in German captivity. These forces fell under the overall command of Helmuth von Pannwitz. In the following year, the 1st Cossack Division and Ukrainian Insurgent Army was supported or created. Although the Cossack units were formed to fight the Bolsheviks, by the time they were formed the Red Army had liberated most of the German-held territory.
