"Otto Langmann (1898-1956) was a German pastor and diplomat.
In November 1923 he married Ilse Siefert, with whom he had four children. He was appointed parish priest in Mecklenburg. In 1928 he went to Colombia and Ecuador. In 1930, in Guatemala, he supported a local evangelical community; a year later he joined the NSDAP and founded the first Nazi group abroad.
He served as the representative of German government in Montevideo, Uruguay (1937-1942) during the Battle of the River Plate in 1939. He held that position until the Uruguayan government broke off relations with Germany." - (en.wikipedia.org 31.12.2019)
