1848: Karl Marx published the Communist Manifesto.
At one point, he could not bring himself to seek employment and in March 1850 he and his wife and four small children were evicted and their belongings seized. Several of his children died, including 2 daughters who committed suicide.
"Every day my wife says she wishes she and the children were safely in their graves, and I really cannot blame her" - Karl Marx in a letter to Freidrich Engels
