"It was a great privilege to work so closely with these wonderful women of our movement...One of the greatest privileges of all was meeting Nadezhda Krupskaya, Lenin's wife, one of the most selflessly devoted human beings I have ever known. She always worked closely with Lenin, helping him in all his problems, and was technical secretary of the Party's Central Committee during their days of exile, a task which involved the handling of voluminous correspondence under conspiratorial conditions, and the most exacting labor with codes. Originally a teacher, her greatest interest was always in education, and her early work in the revolutionary movement had been organizing workers' study circles. As Vice Commissar of Education, she was in charge of adult education in the U.S.S.R. She told me of the immense problem of overcoming the illiteracy inherited from the tsarist regime. On my later visits she always sent for me to ask me for ideas from America which might be useful to the Soviet educational system."
