Schreiner was a metalworker in his youth. In 1910 he joined the Social Democratic Party of Germany and became affiliated with its left wing; in 1919 he joined the Communist Party of Germany. He helped publish works on the history of the German working-class movement. Schreiner went abroad after the establishment of the fascist dictatorship in 1933 and did not return to Germany until 1946. From 1936 to 1938 he served in the international brigades in Spain; he was chief of staff of the 13th International Brigade.
In 1950, Schreiner became associated with the Museum of German History in Berlin, the Institute of History of the German Academy of Sciences, and the Institute of Social Sciences of the Central Committee of the Socialist Unity Party of Germany. His principal works deal with the history of German foreign policy and the influence of the October Revolution of 1917 on Germany. Schreiner received the National Prize of the German Democratic Republic in 1952.
