Rav Yosef Chaim Sonnenfeld.
His biography impacted me more than almost anything else as far as hashkafah and also revealing the hidden & distorted truth of what was really going on in Eretz Yisrael prior to the founding of the Medinah.
He passed on in 1932, just a few months before the Nazis rose to power.
For me, Rav Sonnenfeld encapsulated the ideal of a warrior who battles out of pure love.
Here are past posts about one of the greatest Jews of the 20th century:
