Grüneberg grew up in humble circumstances in Lehnin, Brandenburg. His parents were members of the Communist Party of Germany (KPD) since 1919 and 1928, respectively. From 1928 to 1933, Grüneberg was a member of the Jung-Spartacus League.[1][2]
After completing elementary school, Grüneberg learned the trade of a bricklayer (1936–1939) and worked in this field until his conscription into the Kriegsmarine in the spring of 1941. He served on various ships, reached the rank of a Maat, and was awarded the Iron Cross, 2nd class.[2]
In July 1943, Grüneberg married Elly Lehmann, with whom he had two children. After the war, he was captured by the British and released in August 1945, after which he worked as a bricklayer in Oldenburg, Lower Saxony.[1][2]
Initially, he continued working as a bricklayer and in 1947, spent around six months as a Neulehrer in Oranienburg. The SED then delegated him to the Niederbarnim district party school. Gerhard Grüneberg initially worked in the SED local leadership in Oranienburg and, starting from 1 September 1947, served as the department head for party education, recruitment, culture, and education in the SED district leadership in Guben.[1]
At the age of just 26, he became the First Secretary of the district in 1948, the highest official in the region. In 1948, he attended the state party school in Schmerwitz near Wiesenburg/Mark. After two years as the First Secretary, the SED brought Grüneberg to the Brandenburg State Leadership in 1949. In the state's inner circle of power, the secretariat, he was in charge of cadre work.[1]

In 1958, Grüneberg achieved his next career advancement. He became the secretary of the SED Central Committee for State and Legal Affairs[3] and concurrently became a member of the Volkskammer,[1] nominally representing a constituency in southwestern Bezirk Potsdam.[4]
On 13 December 1959, he became a candidate member and on 15 September 1966, a full member of the Politburo of the Central Committee of the SED.[1][5][6] The Politburo appointed him as the head of their agricultural commission.
SED Agriculture Secretary
In 1960, he became the Secretary for Agriculture of the SED Central Committee.[1][2][5] From 4 July 1962, Grüneberg also served as the 'Minister for Coordinating Tasks in Agriculture' and was a member of the Presidium of the Council of Ministers in 1962/63.[1] Additionally, in 1963, he took charge of the Bureau for Agriculture at the Politburo, became a member of the Council for Agriculture and Food Economy, and from 1966, a member of the Presidium of the GDR Research Council.[1][6]

In the 1960s and 1970s, Grüneberg was the key agricultural policymaker of the SED and thus the GDR.[5][7] As a consequence, he implemented many ideas aimed at industrializing the collectively managed agriculture since 1960. The most significant aspect became the gradual separation of animal and plant production,[2][8] starting in the mid-1960s. This was particularly evident under the leadership of Erich Honecker, under whom Grüneberg expanded his power after falling out of favor with Walter Ulbricht in 1969 due to 'exaggerations.'
By the late 1970s, it became evident that the systematic operational separation between arable farming and animal husbandry was a failure, and the sizes of the farms became almost unmanageable. This led to internal criticism of Grüneberg – notably by the Central Committee Secretary for Economics, Günter Mittag. Grüneberg, together with his ally Bruno Kiesler (Head of the Agriculture Department of the Central Committee), attempted to alleviate the consequences through increased cooperation, which yielded limited success.[2][7][9]
Even before his death, an agricultural policy shift began, intensifying under his successor as the Central Committee Secretary for Agriculture, Werner Felfe.[6]
