Vladimir Ilyich Ulyanov (1870–1924), better known by the alias Lenin, was a Russian communist revolutionary, politician, and political theorist. He played a leading role in the Bolshevik revolution of October 1917.
His mind was a remarkable instrument. When its light shone it revealed the whole world, its history, its sorrows, its stupidities, its shams, and above all its wrongs. It revealed all facts in focus - the most unwelcome, the most inspiring - with an equal ray. The intellect was capacious and in some phases superb. It was capable of universal comprehension in a degree rarely reached among men -- Winston Churchill
