Leon Czolgosz (1873-1901) and President William McKinley, 14 September 1901
The assassin of US President McKinley was inspired by the attack on Umberto I by Gaetano Bresci. Leon Czolgosz was born in the US of East European parents. He adored Emma Goldman, whom he had met once personally, but he failed to make an impression on her. At the Pan-American Exposition 1901 in Buffalo, people were queuing up to shake hands with the president, and Czolgosz was in the queue, his revolver hidden in a handkerchief. Two shots to the president's stomach were fatal. Czolgosz stated from the electric chair: 'I killed the president because he was the enemy of the good people – the good working people. I am not sorry for my crime.' 
Emma Goldman was arrested on suspicion of complicity but later released. In 1903 a bill was passed that prohibited anarchists from entering the US. In those days, about 50 Italian anarchist groups existed in the US, with poetical names such as 'I simpatizzanti di Bresci' (Fan club of Bresci, in Perth, Indiana), 'Gruppo I Morti di Fame' (Those Dead of Starvation, in Iron Mountain, Michigan).
