About the author

Born in Dendermonde, Belgium, in 1801, Pierre-Jean De Smet joined the Jesuits and sailed to the United States in 1821. He was ordained a priest in Missouri and became known for missionary work among Native peoples in the Rocky Mountains and the Pacific Northwest.

De Smet traveled widely across the West at a time when such journeys were slow and dangerous, building relationships with tribes including the Flathead and others. He also served at times as a mediator, carrying messages and taking part in negotiations between Native leaders and U.S. officials, which helped make him a well-known and sometimes controversial figure in frontier history.

He died in St. Louis in 1873. Remembered as the “Black Robe” by many who met him, De Smet left behind letters and travel writings that still shape how readers picture the 19th-century American West.
