Isaac Deutscher was born in 1907 near Krakow and joined the Polish Communist Party in 1926. After his expulsion in 1932, he maintained his opposition to the general drift of Comintern policy in the 1930s. He moved to London in 1939 and continued his journalistic activity until 1946, devoting the rest of his life to historical research and the writing of books and essays. His prolific output includes Stalin and The Unfinished Revolution. Isaac Deutscher died in 1967.
"In the 1930s, Trotsky, with a handful of followers, attempted to block the path of Stalin's relentless hurricane of betrayal and murder. His epic defence of the soul of the Revolution against its bureaucratic executioners was a torchlight in the storm. In one of the very greatest modern biographies, Isaac Deutscher redeems the legacy of this astonishing revolutionary and humanist thinker." -- Mike Davis "This is the critical voice the velvet revolution faded out. The republication of Deutscher's classic trilogy is good news for a new generation who want to know what went wrong with communist-style socialism." -- Sheila Rowbotham ""He has told the story more accurately and with fuller detail than ever before. His book is compulsory reading for anyone interested in the history of Soviet Russia and of international communism."" -- A.J.P. Taylor ""Mr. Deutscher is an exceedingly vivid writer with a sense of style, and a warm understanding sympathy for his hero; this makes him a first rate biographer."" -- Times Literary Supplement ""The three volumes of Deutscher's life of Trotsky ... were for me the most exciting reading of the year. Surely this must be counted among the greatest biographies in the English language."" -- Graham Greene
