it's his birthday

it's the birthday of a very terrible person who had 42 assassination attempts. He was once the leader of Germany around the mid-early 20th century. He hated Jewish people, (which obviously as communists know, all shall be equal) and caused many refugees to have to flee all over the world. Friends with Benito Mussolini, they spread fascism all over the continent of Europe. Although the person was the leader of Germany, he was born in Austria, in the city of Braunau au Imm. Although his Japanese friend caused more deaths than him, he was still the most hated. People in Germany must avoid this name, and it's even more strict than in Israel. 

He is now 134 years old. From his birth on April 20, 1889, to his death, on April 30, 1945 (which he suicide because he did not want to get killed by communists), his life was a roller coaster. He was in jail, then wrote a book, then become chancellor, then dictator, then burned books... it was a mess. 

I gave more than enough clues. You should know who he is. Say happy Birthday to ______ _______!

(no seriously, don't)
