Fritz Samuel, a German Jesuit and missionary, was born in 1650, and died in 1730. He was sent as missionary to South America, and established mission settlements between the Nape and Rio Negro, into which nearly 40,000
natives were gathered. The Portuguese from Brazil attacked and broke up these settlements, carrying many of the Indians to Para. Fritz, after vainly striving to obtain redress, retired to the village of Xeberos in Peru, where he died. His map of the Amazon, though superseded by the fuller dnd exacter works of more recent explorers, procured for him for a long time a just renown as a geographer. — Hoefer, Nouv. Biog.
