Life of Karl Marx
Two of his daughters and a son-in-law committed suicide. Three of his children died of malnutrition. Marx felt no obligation to earn a living, but instead lived by begging from Engels. He fathered an illegitimate child by his maidservant. He drank heavily. He was a paid informer of the Austrian police, spying on revolutionaries. Though Marx and his wife were poor, he kept investing in the stock market where he constantly lost. His wife left him twice, but returned. He didn't attend her funeral. His correspondence with Engels was full of obscenities. His favorite daughter, Eleanor, with her father's approval, married Edward Eveling, a man who advocated blasphemy and worshipped Satan. Daughter Eleanor committed suicide. Karl Marx died in despair.
