"Help Defeat Hitler By Calling Him By His Right Name . . . Schickelgruber!"
Ashamed of his father's family name of Schickelgruber, Adolf was relieved when his natural grandfather, Johann Hiedler (at age 84), legally acknowledged his illegitimate son, Alois Schickelgruber (Adolf's father).

Note that Schickelgruber was actually the maiden name of Adolf's paternal grandmother.
