Helen Keller the well known deaf-blind author, activist and lecturer was a committed socialist through her life.
Fighting for many causes such a labour rights, women's sufferage, socialism and against militarism she dedicated a tremendous amount of her time trying to make the world a better place.
She joined the Industrial Workers of the World, called for strikes against US involvement in World War 1, and demanded an end to the blockade of the newly formed Soviet Union.
The FBI monitored her activities and the 45 page long document on her has since been released publicly.
Her's an archive of some of her writings;
"Oh, where is the swift vengeance of Jehovah, that it does not fall upon the hosts of those who are marshalling machine guns against hunger-stricken people? It is the complacency of madness to call such acts "preserving law and order." Law and order! What oceans of blood and tears are shed in their name! I have come to loathe traditions and institutions that take away the rights of the poor and protect the wicked against judgment.
The wise fools who sit in the high places of justice fail to see that, in revolutionary times like the present, vital issues are settled, not by statutes, decrees and authorities, but in spite of them. Like the Girondins of France, they imagine that force can check the onrush of revolution. Thus they sow the wind, and unto them shall be the harvest of the whirlwind.
You dear comrade! I have long loved you because you are an apostle of brotherhood and freedom. For years I have thought of you as a dauntless explorer going towards the dawn and, like a humble adventurer, I have followed in the trail of your footsteps. From time to time the greetings that have come back to me from you have made me very happy, and now I reach out my hand and clasp yours through prison bars.
With heartfelt greetings, and with a firm faith that the cause for which you are now martyred shall be all the stronger because of your sacrifice and devotion, I am,
Yours for the revolution--may it come swiftly, like a shaft sundering the dark!" ~ Helen Keller, Letter to Eugene V. Debs.
