Was Hitler a free mason

No Hitler was in fact not A Freemason, he even went so far as to say:

Freemasonry has "succumbed" to the Jews and has become an "Excellent instrument" to fight for their aims and to use their "strings" to pull the upper strata of society into their alleged designs. He continues, "The general pacifistic paralysis of the national instinct of self-preservation begun by Freemasonry" is then transmitted to the masses of society by the press.

Hitler believed that '"Freemason's" were in line/allied with the Jews and therefore ordered their destruction.
