Neumann was born in Berlin-Schöneberg and completed training as a joiner. In 1919, he joined the worker's sport club "Fichte", which in 1928 became a member of the "Fighting Community for Red Sport Unity". Neumann became a member of the Communist Party of Germany in 1929, and in 1930, a member of the KG state leadership.
After his return to Germany, he joined the Socialist Unity Party and was an administrative staffer and an SED functionary at the district level in Berlin. In 1949, he became Secretary for Propaganda for the SED Berlin state leadership, from 1951 to 1953, he was East Berlin's acting mayor, and from 1953 to 1957, succeeding Hans Jendretzky, he was First Secretary of the Berlin SED district leadership. From 1949, Neumann was a representative in the Volkskammer, from 1954 a member of the Central Committee and candidate, and from February 1958 a member of the SED Central Committee's Politburo. From 1957 to 1961, he was SED Central Committee Secretary, from 1961 to 1965 chairman of the People's Economic Council, and from 1965 to 1968 Minister of Materials Management. From 1962, he was a member of the Presidium of the Council of Ministers, and in 1968 he was one of the first two acting chairmen of the Council of Ministers. Neumann played an important role in the initiation and implementation of the New Economic System. In the wake of Erich Honecker's removal of Walter Ulbricht in 1971, Neumann, as the only important Politburo member from that time, refused to go along with underwriting a secret request to the Soviet leadership for Ulbricht's redemption, since he was on Ulbricht's side on content and conceptual issues. Erich Honecker would never forget this. Neumann was until the end an uncomfortable antagonist to Honecker, but this was never used in public against him.
Downfall
In 1989, in East Germany's dying days, Neumann went back to join the Council of Ministers and was excluded from the Politburo. He was also excluded from the SED/PDS in 1990. From 1992 he faced accusations of "manslaughter and bodily harm on the inter-German border" for his membership in the East German National Defence Council. The 23rd Penal Chamber of the Berlin State Court, however, stayed proceedings in 1999 without ever arranging a trial. Neumann received in 1956 and 1964 the Fatherland Order of Merit and in 1984 the Order of Karl Marx.
