who was czolgosz?

i read about his execution but ...can someone tell me a little about ?

google czolgosz - you'll find plenty about him, depends what you want to know...

i need to know it generally
i googled it but my english is not great and so i have many difficults with all the historical words . i m just curious about czolgosz and sites always give loong long informations about and so my skimming gets hard

kitten.
I think czolgosz was a kind of terrorist. He tryed to shout president mckinley in USA
in the 1880es. The famous anarchist emma goldman had benn in touch with him. Unknowing that he was a form of agent, who wanted to blame the anarchist movement
in the states............

ah .... thank you a lot
