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."
