Bernhard Bästlein (; 3 December 1894 in Hamburg – 18 September 1944 in Brandenburg an der Havel) was a German Communist and resistance fighter against the Nazi régime. He was imprisoned very shortly after the Nazis seized power in 1933 and was imprisoned almost without interruption until his execution in 1944, by the Nazis. Nonetheless, he was one of the most important leaders of German Resistance. Early years Bernhard Karl Bästlein was born the fourth of five children to Bernhard Bästlein Sr. of Thuringia and Cornelia Bästlein, née Kock, of East Friesland. His father came from a family of toymakers and gunsmiths and worked as a gunsmith and safe builder. He was a member of the Social Democratic Party of Germany (SPD) and an avid trade union member. After grammar school, Bästlein was trained as a precision mechanic. At the same time, he took evening classes at a worker's education school and the Volkshochschule. In 1911, Bästlein finished his training as a mechanic and joined the Socialist Workers Youth Party (Sozialistischen Arbeiterjugend), where he met his future wife, the seamstress Johanna Elisabeth Hermine Berta Zenk, daughter of Wilhelmine (née Schröder) and Albert Zenk, a working-class family and Social Democrats. The following year, Bästlein joined the metal workers' union and the SPD and from 1913 till 1915, he went to work at different armaments factories, at which point he became a soldier and went to fight in France on the western front in 1916. In 1917, he began to write articles about the revolutionary developments then taking place in Russia. Writing under the pen name, "Berne Bums", he took a position of peace through revolution. On returning to civilian life, he was elected to a council of workers and soldiers in November 1918 and he began writing as the "worker correspondent" for the Hamburg Peoples' Press, a volunteer position. He also switched his party affiliation to the Independent Social Democratic Party of Germany (USPD) because of the SPD's stance on war bonds to help pay for World War I. Switch to the Communist Party As the left wing of the USPD merged with the Communist Party of Germany (KPD), Bästlein and his wife joined the KPD. In March 1921, Bästlein was elected to the Hamburgische Bürgerschaft, the legislature of Hamburg. At that time, decisions urged by the Communist International, caused the KPD to incite unrest in Saxony and the Ruhr region.
