Sasha Siemel was a figure of monumental importance on the American hunting-world stage of the 1930s, '40s, '50s, and '60s. He was unique not only as a hunter but also as a man. He is the only known white man to have fought the fierce jungle jaguars of Brazil with a spear, and as a man, he made a stand for decency in everything he did. Siemel published his autobiography, , the basis for this reprint, in 1953, and so great was the demand, the book went through several printings.
