August 5, 1895: Death of comrade Frederick Engels, communist revolutionary and co-founder of scientific socialism.

From “Frederick Engels” by V.I. Lenin

On August 5 (new style), 1895, Frederick Engels died in London. After his friend Karl Marx (who died in 1883), Engels was the finest scholar and teacher of the modern proletariat in the whole world. From the time that fate brought Karl Marx and Frederick Engels together, the two friends devoted their life’s work to a common cause.
