Fritz Müller was born in Forst, on the western shore of the Neisse River and roughly 25 km to the east of Cottbus, in what was then central Germany. His father made cigarettes. He left school and started on a commercial training in 1937. Germany had become a one-party dictatorship during the months following January 1933, and in 1938 Fritz Müller became a member of the ruling Nazi Party. He fought as a soldier in the Second World War, ending up as a Non-commissioned officer. The war ended in May 1945. Between May 1945 and December 1947 Fritz Müller was detained by the Soviet army as a prisoner of war. During this time he joined an Anti-Fascist circle at the Nizhny Tagildetention camp, and was employed in mining. When he returned home at the end of 1947, the frontier on each side of Polandhad moved and Forst was now a frontier town, across the river from Poland. The entire eastern portion of what remained of Germany was now administered as the Soviet occupation zone, and following the contentious creation, in April 1946, of the Socialist Unity Party of Germany was well on its way to reverting to one-party dictatorship. From his subsequent career it is apparent that at some stage, probably before the entire region was re-founded as the German Democratic Republic in October 1949, Fritz Müller joined the young country's ruling SED, but available sources are silent as to when this happened. Back in Forst, in December 1947 he obtained a job in the council planning department, becoming head of department three months later. In 1950 he took on the same job, but now at a regional level, for the Frankfurt district. Shortly after this, in 1951, he became an instructor in the Economic Policy department of The Party's regional leadership for the whole of Brandenburg. However, the regional tier of government was abolished in 1952 as part of a strategy to centralise party/government control, and in August 1952 Müller was given the same job in the city of Cottbus. He left after a few months, to begin in March 1953 a period of study at the Regional Party Academy in Ballenstedt. On graduating he remained at the Party Academy, now as a Deputy Head and Economics teacher between 1954 and 1955. In June 1955 Fritz Müller relocated to Berlin. Here he succeeded as :de:Liste der ZK-Abteilungen und ihrer Abteilungsleiter Leader of the Planning and Finance Department of the Party Central Committee. The country's classic Leninist constitutional arrangements insisted on the "Leading role" of the ruling party, which made the central committee the dominant element in ruling East Germany. In May 1960 Fritz Müller was appointed head of the Central Committee's Cadre Department, a position he would hold for nearly three decades. The post gave him responsibility for the further training of party officers and of officers of the approved mass movements that were a feature of the political structure applied in the Soviet Union and its satellite states. He was also responsible for Personnel Strategy within the SED and thereby also of the entire nomenklatura structure, embracing the relevant organisations and institutions. His own name first appeared on the candidate list for central committee membership in 1963. In 1967 he became one of the 131 members of the Party Central Committee. Additionally, in April 1979 he succeeded as First Secretary in the Central Leadership of the Party Organisation in the Central Committee Apparatus. The changes of 1989/90 heralded the end of the German Democratic Republic as a standalone state, and they also signaled the end of Fritz Müller's political career. On 8 November 1989 the Central Committee Politburo resigned, Müller was relieved of his Central Committee duties on 28 November 1989. A few months later, on 10 February 1990, he was excluded from the Party of Democratic Socialism, the name by which East Germany's old SED was now in the process, slightly hesitantly, of trying to reinvent itself in anticipation of a more democratic future.
