Bertuleit was born in Rund-Görge,[1] now Bendikai [lt] village, just a bit north of Memel, now Klaipėda.
[3] These institutions were used to finance and support pro-Nazi party Socialist People's Union of the Klaipėda Region (Sozialistische Volksgemeinschaft des Memelgebiets or SOVOG), headed by Ernst Neumann.
He received a twelve-year prison sentence but due to the German pressure was released from the Lithuanian imprisonment on 14 February 1938.
Bertuleit participated at the signing of the transfer treaty in Berlin and coordinated the transition until 1 August.
[2] As the Directorate and the Parliament of the Klaipėda Region were liquidated, Bertuleit became a member of the Reichstag on 25 April.
