Max Stirner, by Engels 
'Look at Stirner, look at him, the peaceful enemy of all constraint.
For the moment, he is still drinking beer,
Soon he will be drinking blood as though it were water.
When others cry savagely "down with the kings"
Stirner immediately supplements "down with the laws also."
Stirner full of dignity proclaims;
You bend your willpower and you dare to call yourselves free.
You become accustomed to slavery
Down with dogmatism, down with law.'
- Friedrich Engels 


Marx and Engels, less success than Gilbert and Sullivan.
