Book excerpt: Siegi Moos, an anti-Nazi and active member of the German Communist Party, escaped Germany in 1933 and, exiled in Britain, sought another route to the transformation of capitalism. This biography charts Siegi’s life, starting in Germany when he witnessed the Bavarian uprisings of 1918/19 and moving to the later rise of the extreme right. We follow his progress in Berlin as a committed Communist and an active anti-Nazi in the well-organised Red Front, before much of the German Communist party (KPD) took the Nazis seriously, and his deep involvement in the Free Thinkers and in agit-prop theatre. The book also describes Siegi’s life as an exile: the loss of family, comrades, his first language and ultimately his earlier political beliefs. Against a background of the loneliness of exile, the political and the personal became indissolubly intertwined when Siegi’s wife, Lotte, had a relationship with an Irish/Soviet spy. Lastly, we look into Siegi’s time as a research worker at the prestigious Oxford Institute of Statistics at Oxford University from 1938, becoming an economic advisor under the Labour Prime Minister, Wilson, 1966-1970, and how, finally, after retirement, he returned to writing.
